Windows 8 Activation Error

I use Windows 8 Pro 32 bit. An error happened last night which I don't fully understand which caused some error messages from my installed programs to pop up when I restarted. I used system restore to fix it and the errors were gone and the system seems to work fine except that I am now asked to activate my OS but whenever I'll click the activate button in the control panel an error message will appear:

Error: 0x8007007b The filename, directory name or volume label is incorrect.

I also tried to activate it using the command prompt but I still received the same error message. Please help.

You explained your same issue in greater detail in your last post so why start a new thread on the same issue?
