|OK, it's there and in the right place (C:\Windows\Servicing). Did you get an error message that said it was missing? If so then it seems most likely there has been a registry corruption so that Windows cannot find it. You might be set to hide system files which is why you didn't find it in that location.|
Did you check that the service was setup correctly - see my #9?
We might need to embark on Windows repair but before we go much further do a quick check for malware by running these three freebies in the order given:
(blue "Download Now" button on right).
Download and "Save" the file somewhere. Go to the saved file then double click it to run the program. Use the "Scan" button, followed by the "Clean" button.
Junkware Removal Tool (JRT)
(blue Download button).
Download and "Save" the file somewhere. Go to the saved file then double click it to run JRT. It might appear to have stopped at times or flash the screen but sit tight until it has finished.
(use the "download" button rather than the "buy" button).
Install and Run the program but before running the Scan go to "Settings > Detection and Protection" and put a checkmark in "Scan for rootkits". Quarantine anything it finds.
Please copy/paste the logs on here.
Always pop back and let us know the outcome - thanks
