INFO: Troubleshooting failed installations of Windows Vista SP1

While researching some content, I found this article on Windows Vista Service Pack 1:

At the end of it is a fairly interesting section on "Troubleshooting" failed installations of Windows Vista Service Pack 1.

Troubleshooting

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 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 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
