When applying SP1 for windows 7 there is a specific error that can happen during reboot. If you get this error “Fatal Error C0000034 Applying Update Operation 282 of…”, follow the steps below to fix the SP1 installation

1. Reboot your computer while it’s starting up.

2. When your computer starts up again, choose the option “Launch Startup Repair”

If you do not have this module installed in the OS, you’ll need a Win7 install disc that is the same architecture (i.e. 32 or 64-bit) as the OS installed. Just boot to the CD and go from there.

3. When the Startup repair starts, click cancel.

4. After you click cancel it will show a box. Click “Don’t Send”, then click the link “View advanced options for recovery and support”

5. In the new window click Command Prompt at the bottom.

6. In Command Prompt type this and press enter: %windir%\system32\notepad.exe

7. Notepad will open. In notepad go to File–>Open.

8. Change the type of files notepad views from .txt to All Files

9. Now in Notepad, go to C:\Windows\winsxs\ (or whichever drive Windows is installed on)

10. In that folder, find pending.xml and make a copy of it

Just copy and paste it in the same folder, this is just in case something happens to the original so you don’t lose it.

11. Now open the original pending.xml

It will usually take a while to load because it’s a huge file.

12. Press CNTRL+F and search for the following exactly: 0000000000000000.cdf-ms

That’s sixteen (16) zeroes 😉

13. Delete the following text (yours may be a little different):

<Checkpoint/> <DeleteFile path=”\SystemRoot\WinSxS\FileMaps\_0000000000000000.cdf-ms”/> <MoveFile source=”\SystemRoot\WinSxS\Temp\PendingRenames\e56db1db48d4cb0199440000b01de419._0000000000000000.cdf-ms” destination=”\SystemRoot\WinSxS\FileMa\_0000000000000000.cdf-ms”/>

NOTE: Your PC might not have all 3 sections of code (<Checkpoint>, <DeleteFile>, <MoveFile>). Just make sure you delete section “Checkpoint” and whatever other sections have “000000000000000.cdf-ms”. They will be right next to eachother.

14. Save the file, close notepad, close command prompt, restart your computer.

Conclusion

Once your computer starts up, do a normal startup (it may stall for 5-10 minutes at the “starting windows” screen, but leave it going) and the Service Pack will install some more stuff and restart a few times and then everything should be working! For some people, it reverts everything and cancels the service pack installation. For other people, the service pack installation completes. Either result is fine, the computer should be func tioning normally now without any data loss.
