Thanks Jared.
I just ran the SFCFix program and it repaired two files. A subsequent SFC /Scannow returned no integrity violations. However, there are still issues with the PC. I assume I should post a thread in the Windows Update section or perhaps the browser section... the issue is that Internet Explorer will not update and the various error codes are 8007002 and 3715, along with a "Service Registration is missing or corrupt". If you could point me to the proper area to begin a thread that would be most helpful.
