Windows update Error codes 800736B3 and 9C57
Hi
I have Windows 7, 64 bit Lenovo ideapad that is not allowing system updates. This has been going on for awhile. I do some research on the problem and attempt to fix it myself. When I am unsuccessful I become frustrated so then I don't try again for several months. Meanwhile, my computer performance is getting worse and worse.
What I've tried so far:
- Windows updater troubleshooter:
- Service registration missing or corrupt-FIXED
- Problems installing recent updates-FIXED
- Starting computer in clean boot to try to install updates.
- Temporarily disabling antivirus software (AVG Antivirus Free Edition) and trying to run the updates.
- I've downloaded and tried to run the SURT (not 100% sure if it actually DID run).
- SFC scan did not find any integrity violations.
I was unable to upload CBS zip file to this thread. I tried a few times. Connection was reset.
I have not yet tried to restore the registry because I'm not 100% confident on how to do it although I did backup my computer on an external hard drive.
Please let me know if you require any additional information.
Any insight, advice or help would be greatly appreciated! Thanks!
