Windows XP SP2 - Manual Uninstall

Use Recovery Console to remove Windows XP Service Pack 2:

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

1. Boot from the Windows XP CD.

2. When you receive the Welcome to Setup message, press R to start the Recovery Console.

3. Select the Windows XP installation in question.

Note You must select a number before you press ENTER, or the computer will restart. Typically, only the 1: C:\Windows selection is available.

4. If you are prompted to type an administrator password, do so. If you do not know the administrator password, press ENTER. (Typically, the password is blank.)

Note You will not be able to continue if you do not have the administrator password.

5. At the command prompt, type cd $ntservicepackuninstall$\spuninst, and then press ENTER.

Note After you complete this step, you cannot stop the removal process.

6. At the command prompt, type batch spuninst.txt, and then press ENTER.

Note The Spuninstal.txt file appears. As the file scrolls down, you will see errors and files being copied. This is normal behavior.

7. After Windows XP SP2 is removed, type exit, and then press ENTER.

8. Restart your computer in Safe Mode. To do this, press F8 as the computer restarts.

Note After you restart, the system may lock up with a black screen. (Your mouse will work.) In this case, restart again by turning the computer off and then back on. The second restart will let you to log on.

9. When your computer restarts, Windows Explorer (Explorer.exe) does not run, and the Windows icons and the Start button are unavailable. To resolve this problem, follow these steps:
a. Press CTRL+ALT+DEL to start Task Manager.
b. Click File, and then click New Task (Run...).

Domain Password Reset

1. Use the Astrami CD to reset the MACHINE Administrator password to "no password".

2. Reboot, hit F8, and enter "Directory Service Recovery Mode". The machine will boot up as a standalone server
without any Active Directory support.

3. When the login screen appears, hit CTRL-ALT-DEL and log in as "Administrator" with no password. This is the
MACHINE Administrator account, and does not have the ability to modify anything specific involving the
Active Directory information, although it can backup and restore the physical files which contain the AD databases.

4. Run "REGEDIT.EXE" (without the quotes). Navigate to HKEY_USERS\.Default\Control Panel\Desktop

*** Lamer note: Make sure you write down the default values BEFORE changing them.
You could also just PRINT SCREEN your registry editor display.
The best option is to just backup the values to a .REG file by selecting the
DESKTOP key and then selecting EXPORT from the FILE menu.

After you made sure you know what the default values are, change the following values:

SCRNSAVE.EXE - change from logon.scr to cmd.exe

ScreenSaveTimeout - change from 900 to 15

ScreenSaveActive - change to 1 (if it wasn't 1 already)

5. Reboot normally. When the box appears asking you to hit CTRL-ALT-DEL to log in, just wait.

After 15-30 seconds you will see a command prompt appear (since that is the screensaver).

6. In the command prompt, type the following command: MMC DSA.MSC

*** Lamer note: There is a space character between the "mmc" and the "dsa.msc".
Also, note that the DSA.MSC file is usually located in the SYSTEM32 subfolder
of your WINDOWS or WINNT folder.

**** More lamer notes: DSA.MSC is actually the executable name for Active Directory Users and Computers,
which in turn is the main tool for managing users, groups and computers in Windows 2000 Active Directory.

This should bring up the management console where you can edit users' passwords,
including the password for the Administrator account.

7. After resetting the Administrator password, exit the management console and type the command EXIT in the command prompt window.

8. Hit CTRL-ALT-DEL and log into the DOMAIN Administrator account using the new password!

9. Don't forget to restore the changes you made to the registry in step 4.
