For some time now I have been unable to update Windows Vista 64 Home Premium (PC shows the message: "Windows can't update important files and services while the system is using them...restart the computer"). I am also finding that the system files checker
(scannow) does not work (the window shows an error message reading: "There is a system repair pending which requires a reboot to complete."). No matter how many times I restart the PC, the results and messages for both issues remain unchanged. When I am
successful downloading an update, I often find it will not install and receive error code 80070BC9. My HP IQ506 is set to download updates automatically, but never does.
I have used McAfee Security Suite Elite (AT&T U-verse provision) on this PC for over 2 years. McAfee online technical support removed their product (including all registry entries) from my PC to determine if they were causing a 3rd party conflict. They also did an in-depth review of my PC for infections using tools available to their Tech Support personnel. No problems were found. Based on Community recommendations, I have scanned for malware (Malwarebytes, Super Antispyware,etc) with no success. I have used numerous MSFT tools and manually downloaded hotpatches (MSFT Fix It Center, Defender, Systems Update Readiness Tool - KB947821, etc.). Only AFTER these system problems started, I downloaded and used certain 3rd party utilities such as Tweaking.com, C Cleaner, Wise Reg Cleaner, etc.
I have confirmed Windows and related "services" are running (also restarted these services) and were set to "automatic" on the MSFT Console. I am reasonably confident that there are no malicious "bugs" in the system. I don't know if it is a coincidence, but these problems started right after MSFT did a number of "automatic" downloads a while ago.
I have noted that some of the registry repair utilities, including Tweaking.com, all get "hung up" (loop?) at the same spot in the registry. This registry location is shown in the Title above. Since I am not registry proficient, I do not know if the repetition of WOW 6432 over 10 times at one location in the registry is an issue or not. Nor am I sufficiently confident in my technical skills to attempt a registry repair without guidance.
Any assistance would be greatly appreciated. Dottie
