This morning, 8 of our PCs booted into an error which read "Fatal Error C0000034 applying update operation ...". Cannot go into Safe Mode. These are all 64 bit Windows 7 machines. They are all the same model - Dell Optiplex 780.

I'd first recommend a system restore to an earlier date.

Or you could hit F8 while booting, then boot from the last known good state.

Once in, clean up the workstations as much as possible (I'd suggest a couple of passes with CCleaner, both its cleanup function and registry cleaner).  Then try the updates manually.

Sounds like you installed SP1?

Per http://answers.microsoft.com/en-us/windows/forum/windows_7-system/fatal-error-c0000034-on-boot-after-service-pack-1/5f7127e8-9887-4f01-aaa5-9729b69544b7

It essentially involves doing a manual system restore.

- Open the recovery console

- Change working directory to whatever the root folder of the Windows install is (might be D: or some other letter for some people):

cd /d C:\windows\system32\config

Rename the following files by typing the following:

ren default default.old
ren sam sam.old
ren security security.old
ren software software.old
ren system system.old

- Change the working directory:

cd regback

- Copy the files from this directory to the previous directory as follows:

copy default c:\windows\system32\config
copy sam c:\windows\system32\config
copy security c:\windows\system32\config
copy software c:\windows\system32\config
copy system c:\windows\system32\config

- Having done this, I restarted my computer, and it booted all the way with no errors. However, it seemed somewhat unstable, so I booted into Safe Mode and ran CHKDSK (chkdsk /B) and conducted a normal system restore to before the service pack install using the normal method. To fix remaining problems, I ran sfc /scannow. My computer now seems to be running as well as ever.

Try these

"Your computer may freeze or restart to a black screen that has a "0xc0000034" error message after you install Windows 7 Service Pack 1 or a Windows Vista service pack"

Split the points, as both experts had identical solutions. Problem resolved, and PCs running again. Thanks for the help.
