Well I Updated my computer (Automatic Update) and right after it restarted the computer an error box popped open saying a file was missing and it could not run explorer.exe

I ran TASK manager and tried to run the system restore exe (rstrui.exe) but the window came up blank.

Is there anyway to fix this?

Thanks in Advance. Welcome to the CH forums.

Please read this...

Which file(s) is(are) missing?Well Possibly All *.dll Files are missing from the System32 Folder.If you can BOOT into SafeMode with no problems you could try to do a System Restore......but if all the.dll files are missing ( which is weird, well i guess not when a Windows Update is in the equation ) you should try running chkdsk /r from the Recovery Console to SEE if that recovers some of the FUNCTIONALITY to your system. But seriously, if all the dll files were missing from /system32, I wouldnt see how ud get as far as you're getting now. GO to Start/Run and type in sfc /scannow and hit Enter...have your XP CD handy as it will ask for it...Try to download and install Library Files from here:

This helped me once.
