Uninstalling SP1You can remove SP1 by using either Programs and Features (in Control Panel) or the command line. Note, however, that you cannot uninstall SP1 offline by using any method. In addition, it is not possible to uninstall the permanent prerequisite updates (KB949939, KB937287, KB935509, and KB938371), although you can uninstall KB936330 and KB937954. You also cannot uninstall the service pack and other updates that were installed by using an integrated installation. For more information about uninstalling using the command line, see KB article 940410 at
http://go.microsoft.com/fwlink/?LinkId=115520.
To uninstall SP1 by using Programs and Features
1. Open

To uninstall SP1 by using the command line 1. Open an elevated Command Prompt window (click
Start, type
command in the
Start Search box, right-click
Command Prompt, and then click
Run as administrator).
2. Run the following command (assuming that Windows6.0-KB936330.exe is in the C:\temp folder):
C:\temp\Windows6.0-KB936330-X86.exe /x:C:\temp 3. To create a sandbox (a virtual environment), type
md <sandbox>.
4. To remove SP1, type

TroubleshootingTo confirm that SP1 is installed, right-click
Computer and then click

If a hardware device does not function correctly after you install SP1, it may be because of a problematic driver. For a list of problematic drivers, see the “Method for Cause 5” section of KB article 948343 (
http://go.microsoft.com/fwlink/?LinkId=115521). For information about how to fix driver issues, see
http://go.microsoft.com/fwlink/?LinkId=113062.
When installing SP1, some computers may run into issues that block the installation or otherwise cause it to fail. These issues may include the following:
* A problematic driver
* A hard disk that is corrupted
* Memory failures
* Software and file system synchronization issues. For performance reasons, the file system keeps a copy of the contents of some files in the memory, and it can take a while for these contents to be written back to the hard disk. Therefore, sometimes the contents of the files on the hard disk may be slightly out of synchronization with the memory.
To work around installation problems, perform the following steps in the specified order:
1. Ensure that you do not have a problematic driver, see the “Method for Cause 5” section of KB article 948343 (
http://go.microsoft.com/fwlink/?LinkId=115521)
2. Ensure that you have enough disk space, as specified in the "Check disk space requirements" table under
Perform predeployment tasks earlier in this guide. Then restart the computer and try again to install SP1. This will ensure that all files are synchronized properly.
3. If the installation still fails, open an elevated Command Prompt window, and then run the
chkdsk /f command. The Chkdsk tool checks the file system and metadata for errors, and then it fixes the errors, if possible. Then try again to install SP1.
4. If the installation still fails, open an elevated Command Prompt window, and then run the
SFC /scannow command. The System File Checker tool scans all protected files to verify their versions, and then it updates these files, if possible. Then try again to install SP1.
5. If the installation still fails, open an elevated Command Prompt window, and then run the
MdSched.exe command. The Windows Memory Diagnostic tool tests the random access memory (RAM) on your computer for errors. Then try again to install SP1.
6. If the installation still fails, download and extract the KB947821 update from the Microsoft Download Center. The Windows6.0-KB947821-XXX.msu file will ensure that the computer is ready to be updated. Then try again to install SP1.
