  2. hello Sam bit,
    You helped a computer idiot to solve the problem that even the online expert could not solve. I’ve been suffered from reboot and reboot for a year and now the problem has been solved forever. Thank you.

  3. Thanks Sambit,
    You were spot on for the reset of windows update! KB5001330 was stuck in a file error when installing, followed your “Very Clear” instructions and was able to rerun the windows update, although I still get the error when installed at 100% “some update files are missing” I’m now able to work around the update that failed.

  4. Your tip on restarting the Windows Update Auto Update Client was GOLD! I’ve scoured tech support forums all over the web trying to fix an issue I was having with some Windows store apps. I even reset my whole PC to factory defaults in desperation when I couldn’t diagnose and resolve the issues using Procmon and Windows Event Viewer (it was due for a refresh anyway), and the problem returned almost immediately. All it took was a measly little one liner, who woulda thunk it?

  5. Hi Sambit, I haven’t done what you said here yet, but I want to tell you that these are the most clear instructions I have ever seen about doing something on computers, and I want to thank you very much for that. I’m going to come back to your website whenever I have questions.
