Useful Windows XP DOS Commands & Tricks

Typing DOS commands on the Windows Command Line prompt is a most efficient and faster way of doing things in Windows XP. Here's a run-down of the most useful DOS commands available in Windows XP. Some of these DOS commands even do not have an visual alternative.

DOS Command-line tools must be run at the prompt of the Cmd.exe command interpreter. To open Command Prompt, click Start, click Run, type cmd, and then click OK.

ipconfig - Windows IP configuration
Useful for troubleshooting your internet connection. Displays the current IP address of your computer and the DNS server address. If you call your ISP for reporting a bad internet connection, he will probably ask you to run ipconfig.

fc - Free BeyondCompare in XP
FC is an advanced DOS Command that compares two files and displays the differences between them. Though the file comparison results are not as interactive as BeyondCompare or Altova DiffDog, fc is still very useful. You can even set fc to resynchronize the files after finding a mismatch.

type - open text files sans Notepad
Similar to Unix cat command, Type is my favorite DOS command for displaying the contents of a text files without modifying them. When used in combination with more switch, type splits the contents of lengthy text files into multiple pages. Avoid using the type command with binary files or you'll hear alien PC beeps and see some greek characters on your PC.

ping - Say hello to another computer
Ping network command followed by the web-address or IP address tells you about the health of the connection and whether the other party is responding to your handshake request. Ping tool can also be used to convert the web address to a physical IP address.

tree - visual directory structure
You often need to take prints of your physical directory structure but XP has no simple "visual" commands for printing directory contents. Here, try the Tree DOS command and redirect the output to a text file.

tree > mydirectory.txt
print mydirectory.txt

attrib - make hidden files visible
Attrib lets you change attributes of System files and even hidden files. This is great for troubleshooting Windows XP. Say your XP doesn't boot ever since you edited that startup boot.ini file (Hidden), use attrib to remove the Hidden attibute and edit the file using EDIT dos command.

assoc - which program will open that .xyz file
The assoc DOS command can be used to either isplay or even modify the file name extension associations. The command assoc .htm will quickly tell you the name of your default web browser (see picture)

move - more flexible than copy-paste
Say you got a lot of XLS and DOC files in you MyDocuments folder and want to move only those XLS files that have their name ending with 2006. In XP Explorer, you have to manually select each file and then cut-paste to another folder. However, the DOS move command make things much simpler. Just type the following at the command prompt:
move *2006.xls c:\2006Reports\

find - advanced file search with filter
Find is the most powerful DOS command and even more useful than the Windows Desktop Search tool or the Windows Find Wizard. The find command searches for a specific string of text in a file or files. After searching the specified file or files, find displays any lines of text that contain the specified string.

To search your hard disk to find and display the file names on drive C: that contain the string "Google" use the pipe (|) to direct the results of a dir command to find as follows:
dir c:\ /s /b | find "Google"

Quick tip - Drag to avoid typing: When your command acts on a file or folder, you must type the path to that folder after the command. You can save typing time by dragging the file or folder from Windows Explorer into the command window.

8 hacks to make Firefox ridiculously fast

Firefox has been outperforming IE in every department for years, and version 3 is speedier than ever.

But tweak the right settings and you could make it faster still, more than doubling your speed in some situations, all for about five minutes work and for the cost of precisely nothing at all. Here's what you need to do.

1. Enable pipelining

Browsers are normally very polite, sending a request to a server then waiting for a response before continuing. Pipelining is a more aggressive technique that lets them send multiple requests before any responses are received, often reducing page download times. To enable it, type about:config in the address bar, double-click network.http.pipelining and network.http.proxy.pipelining so their values are set to true, then double-click network.http.pipelining.maxrequests and set this to 8.

Keep in mind that some servers don't support pipelining, though, and if you regularly visit a lot of these then the tweak can actually reduce performance. Set network.http.pipelining and network.http.proxy.pipelining to false again if you have any problems.

2. Render quickly

Large, complex web pages can take a while to download. Firefox doesn't want to keep you waiting, so by default will display what it's received so far every 0.12 seconds (the "content notify interval"). While this helps the browser feel snappy, frequent redraws increase the total page load time, so a longer content notify interval will improve performance.

Type about:config and press [Enter], then right-click (Apple users ctrl-click) somewhere in the window and select New > Integer. Type content.notify.interval as your preference name, click OK, enter 500000 (that's five hundred thousand, not fifty thousand) and click OK again.

Right-click again in the window and select New > Boolean. This time create a value called content.notify.ontimer and set it to True to finish the job.

3. Faster loading

If you haven't moved your mouse or touched the keyboard for 0.75 seconds (the content switch threshold) then Firefox enters a low frequency interrupt mode, which means its interface becomes less responsive but your page loads more quickly. Reducing the content switch threshold can improve performance, then, and it only takes a moment.

Type about:config and press [Enter], right-click in the window and select New > Integer. Type content.switch.threshold, click OK, enter 250000 (a quarter of a second) and click OK to finish.

4. No interruptions

You can take the last step even further by telling Firefox to ignore user interface events altogether until the current page has been downloaded. This is a little drastic as Firefox could remain unresponsive for quite some time, but try this and see how it works for you.

Type about:config, press [Enter], right-click in the window and select New > Boolean. Type content.interrupt.parsing, click OK, set the value to False and click OK.

5. Block Flash

Intrusive Flash animations are everywhere, popping up over the content you actually want to read and slowing down your browsing. Fortunately there's a very easy solution. Install the Flashblock extension (flashblock.mozdev.org) and it'll block all Flash applets from loading, so web pages will display much more quickly. And if you discover some Flash content that isn't entirely useless, just click its placeholder to download and view the applet as normal.

6. Increase the cache size

As you browse the web so Firefox stores site images and scripts in a local memory cache, where they can be speedily retrieved if you revisit the same page. If you have plenty of RAM (2 GB of more), leave Firefox running all the time and regularly return to pages then you can improve performance by increasing this cache size. Type about:config and press [Enter], then right-click anywhere in the window and select New > Integer. Type browser.cache.memory.capacity, click OK, enter 65536 and click OK, then restart your browser to get the new, larger cache.

7. Enable TraceMonkey

TraceMonkey is a new Firefox feature that converts slow Javascript into super-speedy x86 code, and so lets it run some functions anything up to 20 times faster than the current version. It's still buggy so isn't available in the regular Firefox download yet, but if you're willing to risk the odd crash or two then there's an easy way to try it out.

Install the latest nightly build (ftp://ftp.mozilla.org/pub/firefox/nightly/latest-trunk/), launch it, type about:config in the address bar and press Enter. Type JIT in the filter box, then double-click javascript.options.jit.chrome and javascript.options.jit.content to change their values to true, and that's it - you're running the fastest Firefox Javascript engine ever.

8. Compress data

If you've a slow internet connection then it may feel like you'll never get Firefox to perform properly, but that's not necessarily true. Install toonel.net (toonel.net) and this clever Java applet will re-route your web traffic through its own server, compressing it at the same time, so there's much less to download. And it can even compress JPEGs by allowing you to reduce their quality. This all helps to cut your data transfer, useful if you're on a limited 1 GB-per-month account, and can at best double your browsing performance.

Convert Windows XP Guest Account to Admin

Using simple command line tools on a machine running Windows XP we will obtain system level privileges, and run the entire explorer process (Desktop), and all processes that run from it have system privileges. The system run level is higher than administrator, and has full control of the operating system and it’s kernel. On many machines this can be exploited even with the guest account.

Follow these steps:
1. open command prompt (Start->Run->cmd),
2. enter the following command, then press ENTER]:
at 15:25 /interactive “cmd.exe”
Lets break down the preceding code. The “at” told the machine to run the at command, everything after that are the operators for the command, the important thing here, is to change the time (24 hour format) to one minute after the time currently set on your computers clock, for example: If your computer’s clock says it’s 4:30pm, convert this to 24 hour format (16:30) then use 16:31 as the time in the command.
When the system clock reaches the time you set, then a new command prompt will magically run. You’ll notice that the title bar has changed from cmd.exe to svchost.exe (which is short for Service Host). Now that we have our system command prompt, you may close the old one. The difference is that this one is running with system privileges (because it was started by the task scheduler service, which runs under the Local System account).
3. enter the following command, then press ENTER]:
compmgmt.msc
this will open the computer management console
4. Go to local users and groups->users.
Right click on any user and select "set password".
its done now...

if it says access denied do this


start>run>cmd

net use \\(your ip add)\IPS$ /u:Administrator

or

start>run>cmd
then use following commands
1) net user test /add (this command will make test named user)
2) net localgroup administrators test /add (this command will make test user as administrators rights)

and use net user command to reset your admin. password

Top Ten New Features in Windows Vista

Windows Vista, scheduled for release on January 30th, 2007 has something for everyone, from tight security and stunning new graphics to some new bundled applications. In fact, there is much that this new operating system has to offer, that it will be a real test for the hardware configuration of your PC. With its sleek new look and eye-catching interface, actually it's what's under the hood that impresses the most. Microsoft's done a great job of improving security across the board as this was their priority when they were developing Vista in the first place. Features like Windows and spyware library updates are streamlined, and I definitely appreciate the more robust Backup software.

Internet Explorer is the new web browser that comes with Windows Vista, but as we all know you can download it for XP as well, so this article won't focus on it. Windows Media Player 11 can also be installed to the XP system. A really intriguing stuff is the Windows Sidebar, which puts real-time weather info, stock quotes, system status, RSS feeds, and other information on the display.

This article puts the focus on the top new features in Window Vista, things that can’t find in the XP. Apart from this article, another really great site about Windows Vista full of information about the new features is vista-hq.com.

1. New User Experience, including Windows Aero

Windows Vista features four different levels of user experience—Basic, Windows Classic, Standard, and Windows Aero™. All controls are totally redesigned in Windows Vista and look even better now. The Aero user interface is the top of the line and takes advantage of the latest advances in computer hardware. On computers equipped with graphics hardware that supports the new Windows Driver Display Model (WDDM), the Aero provides more stability and smoother window handling. The main element of this interface is the transparent glass design, with subtle effects such as dynamic reflections and smooth animations. To checkout some screenshots, go to vista-hq.com/interface.html.

2. Windows Sidebar

The Windows Sidebar can be positioned on the right or on the left side of your screen and its associated with mini-applications called gadgets, that provide specific information. Like for example, the gadgets can give you info on the weather, show you the calendar, games, a calculator or all types of other tools. The Sidebar fits perfectly especially on widescreen monitors. It can be easily customized and you can add different types of gadgets. Gadgets are a new concept introduced in Windows Vista. They can connect to web services to deliver business data, weather information, news updates, traffic maps, Internet radio streams, and even slide shows of online photo albums. By default, the OS comes with a set number of gadgets to get you started, but you can always download more from an online gadget gallery.

3. The Instant Desktop Search

The Instant Search is a new feature that will help you find whatever you're looking for. It is available almost everywhere in Windows Vista, in the Explorer Dialogs, in the Start Menu, pretty much in every system window. Using it, you can type a filename, a property, or even text contained within a file, and it returns pinpointed results. Besides that, the Instant Search also arranges the results depending on your current activity, whether it’s searching for music files in Media Player, or looking over all your files and applications on the Start Menu. You can check out some screenshots of that at vista-hq.com/interface.html.

On the Start Menu, the Instant Search box is located at the lower left corner, and instead of going through all the programs installed in order to find the one you are looking for, you can just type its name in the box and as you type, Windows Vista instantly searches file and application names, metadata, and the full text of all files, and it displays the search results. It searches through everything - Applications; Favorites/Internet History; Files, including documents and media; and Communications, including email, events, tasks, and contacts.

4. Windows Defender

Windows Defender is a features that protects your computer from pop-ups, slow performance, and security threats caused by spyware. It works by monitoring key system locations for changes that signal the presence of spyware. The autoupdate option will make sure that the Defender has all the latest spyware definitions from Microsoft. The interface is simple and easy to use, making daily tasks like as scanning, blocking, and removing unwanted software easier than ever. It has a built in Software Explorer that determines which software and services are running on your computer and stops or disables “rogue” software.

It works in co-operation with Internet Explorer with the "Scan on execute" feature. This feature provides an added layer of protection, by scanning all downloaded files before they are saved and executed, thus reducing the chance that spyware might be installed by accident. If you want to learn something more about the Windows Defender visit vista-hq.com/security.html.

5. Performance Center

The Performance Center is a brand new tool that gives information on the PC’s performance characteristics and can manage and troubleshoot performance issues. The very interesting thing here is the WinSPR, or Windows System Performance Rating. This rating is from 1 to 5, and depending on your rating, you can determine if a given application can run on your machine. For example, if you have some of the latest hardware, your rating can reach 4.2 and it that case, any software with 4.2 or lower WinSPR will run smoothly on your computer. To find out more about it, go to vista-hq.com/performance.html.

6. Backup and Restore

This new functionality makes it possible for you to keep your information safe from user error, hardware failure, and other issues that can result in data loss. There are several layers of protection to ensure maximum effectiveness. From the Backup and Restore control panel, you can enable the auto feature which automatically caches previous versions of your files to an image-based backup of your entire computer. Later, you can browse and search for files to restore from a backup.

Another great new feature allows you to access previous versions of files without even having a backup. This is possible through the Volume Shadow Copy technology. If you want to do that manually, then you will have to use the File Back Wizard in which you select the types of files you want to backup, specify a storage folder and start the process at any point you want. There is also an automatic scheduling function.

The system restore feature can reverse system changes, but still preserving your data in its current state.

7. Network Map

The Network Map is a new feature inside the Network Center that displays graphically your connectivity to the network and to the Internet. If a computer on the network loses Internet connectivity, you can graphically see which connection is down and then use Network Diagnostics to help determine the cause of the problem and find possible solutions.

This is especially useful if you have a network of wired and wireless PCs and devices. With the Network Map you can increase the performance of the network and easily spot problems.

8. Windows ReadyBoost

ReadyBoost is a brand new technology that comes with Windows Vista. It's a whole new concept that will change they way people add memory to a system. With ReadyBoost, you can use USD flash as RAM to extend system memory and improve performance. So instead of buying RAM and opening your computer, you can just plug the Flash. Plus, most motherboards have just two RAM slots, which will be taken anyway.

Utilizing this technology is simple. Just plug the Flash in the USB slot and Windows Vista will check to determine if its performance is fast enough to work with Windows ReadyBoost. If that's the case, then you’ll be asked if you want to use this device to speed up system performance. ReadyBoost is reliable as well as secure. You won't loose any data, and the system will restore to its original level of performance when the Flash is removed. There is no wearing on the USB drive, because of the specifically optimized algorithms used.

9. Windows Ready Drive

Windows ReadyDrive takes advantage of the latest hybrid hard drives to provide faster boot-up, hibernate, and resume. It works by writing data to the flash memory on the hybrid hard disk, which lessens the amount of spinning for the mechanical hard drive, thus saving battery power. And also increases the life of your hard drive. With a hybrid drive, Windows Vista can resume more quickly from Sleep because data can be restored from flash memory faster than from the spinning mechanical hard drive.

10. Windows Media Center

For a large number of users, the PC has become mostly a source of entertainment, that you can enjoy by sitting back with a remote control in hand. That's not something strange considering the enormous amount of media files that you can download online. The Windows Media Center enables you to enjoy live and recorded TV, music, photos, videos, and online entertainment on a single device. It can also be connected to Xbox 360 allowing you to transfer this experience in other rooms of your home.

It's integrated in the Home Premium and Ultimate editions of Windows Vista and also offers built-in support for archiving TV shows to DVD. It takes advantage of the very latest technologies including a support for widescreen and high-definition (HD) displays. There are three separate sections - music, digital photos, TV and movies. In the Music section, you can quickly browse your music by artist, song, or album title, as well as by genre, composer, or year. Regarding the photos, Windows Media Center can turn your simple photo collection into a cinematic slide show that can be shared on the television in the living room. On top of that, WMC provides seamless experience when watching your favorite television shows and movies.
