Reinstalling windows wuthout losing anything!!!

You can use this method as often as you like when you need to repair something that had gotten corrupted and you don't want to do a clean install.

This is better than doing a windows repair install from the cd because doing that can cause changes to settings and even make it so you can't get updates anymore from microsoft update site because of the 'silent install' they did a year or so ago (unless you rereg some dll files).

1- Start WindowsXP
2- Go to the location of your source files
3- Run WINNT32 /unattend
For example, D:\I386\winnt32 /unattend ( copy & paste this command into the RUN box, then press ENTER ) Your computer will do the rest.

Windows 7 vs. Vista vs. XP performance shootout - which is best?

Rather than publish a series of synthetic benchmark results for the three operating systems (something which Microsoft frowns upon for beta builds, not to mention the fact that the final numbers only really matter for the release candidate and RTM builds), ZDnet’ve decided to put Windows 7, Vista and XP head-to-head in a series of real-world tests to find out which OS comes out top.

Let’s look at the test systems and the tests …

The test systems

I’ve used two desktop systems as the test machines:

    * An AMD Phenom 9700 2.4GHz system fitted with an ATI Radeon 3850 and 4GB of RAM
    * An Intel Pentium Dual Core E2200 2.2GHz fitted with an NVIDIA GeForce 8400 GS and 1GB of RAM

The tests

There are 31 tests in all, most of which are self explanatory:

   1. Install OS - Time it takes to install the OS
   2. Boot up - Average boot time to usable desktop
   3. Shut down - Average shut down time
   4. Move 100MB files - Move 100MB of JPEG files from one hard drive to another
   5. Move 2.5GB files - Move 2.5GB of mixed size files (ranging from 1MB to 100MB) from one hard drive to another
   6. Network transfer 100MB files - Move 100MB of JPEG files from test machine to NAS device
   7. Network transfer 2.5GB files - Move 2.5GB of mixed size files (ranging from 1MB to 100MB) from test machine to NAS device
   8. Move 100MB files under load - Move 100MB of JPEG files from one hard drive to another while ripping DVD to .ISO file
   9. Move 2.5GB files under load - Move 2.5GB of mixed size files (ranging from 1MB to 100MB) from one hard drive to another while ripping DVD to .ISO file
  10. Network transfer 100MB files under load - Move 100MB of JPEG files from test machine to NAS device while ripping DVD to .ISO file
  11. Network transfer 2.5GB files under load - Move 2.5GB of mixed size files (ranging from 1MB to 100MB) from test machine to NAS device while ripping DVD to .ISO file
  12. Compress 100MB files - Using built-in ZIP compression
  13. Compress 1GB files - Using built-in ZIP compression
  14. Extract 100MB files - Using built-in ZIP compression
  15. Extract 1GB files - Using built-in ZIP compression
  16. Compress 100MB files under load - Using built-in ZIP compression while ripping DVD to .ISO file
  17. Compress 1GB files under load - Using built-in ZIP compression while ripping DVD to .ISO file
  18. Extract 100MB files under load - Using built-in ZIP compression while ripping DVD to .ISO file
  19. Extract 1GB files under load - Using built-in ZIP compression while ripping DVD to .ISO file
  20. Install Office 2007 - Ultimate version, from DVD
  21. Open 10 page Word doc - Text only

Keyboard vs. Mouse

Keyboard vs. Mouse - Today's Winner: The Keyboard (poor little mouse!)[/SIZE]

Windows XP Home and Professional (Some work on other versions of Windows too!)

The Windows key brings up the Start menu,  but it also does quite a lot more too!:

Winkey-D press it to view your desktop, press it again to go back to where you were :-)

Winkey-M minimizes all windows.

Winkey-E opens the Windows Explorer.

Winkey-L locks your system until you enter your password—or lets you switch active users (if you have Fast User Switching enabled).

Winkey-R brings up the Run dialog.
Winkey Pause/Break key- brings up the System Properties dialog.
Winkey-U opens the Windows Utility Manager, (accessibility program options).

Winkey-S, in Microsoft Word 2002 or later, invokes Windows' text-to-speech engine, which will read either highlighted text or everything from the cursor on. (It's very annoying too.)

Access Stored User Names and Passwords with rundll32.exe

The Stored User Names and Passwords applet lets you assign user names and passwords to use when needing to authenticate yourself to services in domains other than the one you are currently logged into. The normal way of running this applet can be difficult to find quickly, so here is a way to launch it using a desktop shortcut using the rundll32.exe program:

Click on START - RUN and type the following (follwed by ENTER):



rundll32.exe keymgr.dll,KRShowKeyMgr
