Hi everyone. I recently built the computer that I am on and installed Windows 7 Ultimate 64-bit in December.
Everything's been working great and no updates have had issues installing until SP1 came out today. It fails every time with error code 80004005, unknown error. I am fairly certain that it is due to the Windows Mail hack, but any attempt to restore the files back to the original versions (I've tried copying them from another machine and sfc /scannow) have not resolved the issue.
On another note, I've read that the same error came up when people did service pack installs for Vista. I have attempted many of the "best practice" fixes for these cases - disabling services, antivirus, startup entries, etc., but this has not resolved the issue, either.
Any advice/suggestions would be great. Thank you in advance!
