Hi,
Please try the following steps.
Check for malware:
Download, install, run, update and perform full system scans with the following two applications:
Removing everything they find. Rebooting when needed. (You can uninstall one or both when done.)
Then perform an online scan with the
eSet Online Scanner.
Reboot.
Now reset your Windows Update Components with this FixIt:
How do I reset Windows Update components?
Reboot.
Try getting updates.
If it still fails, try this...
- Start an elevated command prompt.
- Run the following commands hitting enter after each line:
net stop wuauserv
cd %systemroot%
ren SoftwareDistribution SoftwareDistribution.old
net start wuauserv
- Reboot
- Try to install updates again
**Important** The following issues occur when you do this:
- Updates that are currently downloaded but that have not yet been installed have to be downloaded again by using Windows Update or Microsoft Update.
- When you delete the Software Distribution folder, your download history is removed.
- If you currently receive updates from Microsoft Update and from Windows Update, you will have to re-select this option from the Windows Update Web site.
