Windows 7 Service Pack 1 – Installation Failure ERROR_ACCESS_DENIED (0x80070005)
When Windows 7 Service Pack 1 was made available last week, I eagerly downloaded it and then attempted to install it on my laptop, at which it failed. The error message was not particularly helpful either.
So following the instructions, I disabled my anti-virus and repeated the process, but once again I received ERROR_ACCESS_DENIED(0x80070005).
Having worked with Windows for many years, I knew to go on the hunt for the installation logs.
Navigating to C:\Windows\Logs\CBS, I located the log called CBS.log
Opening the log file I searched for the usual negative terms such as failure, denied and error, with Error giving me the most results.
I found multiple references in the CBS.log such as these.

I am not sure as to why these updates were reporting an ERROR_NOT_FOUND message, but after fully examining the CBS.log file I was left with a list of these updates (Note: this is my list of updates to remove, yours could be different).
Opening from the Control Panel, Programs and Features and then by selecting “view installed updates”, I removed all the listed updates that reported ERROR_NOT_FOUND in the CBS.log.
I then rebooted and attempted to reinstall Windows 7 Service Pack 1 again and hey presto, after about an hour, my laptop was up and running with Windows 7 Service Pack 1.
When I get time, I will investigate why I got these errors in the first place, but for me the important thing was getting Service Pack 1 on the laptop. I am coming to the conclusion this issue was caused by having a pre-release of the service pack on my laptop as my other machines, which did not have a pre-release version of Service Pack 1 installed have been error free.
I HOPE THIS HELPS, THIS SOLUTION WORKED FOR ME, BUT DOES NOT MEAN IT WILL WORK FOR YOU.
