Sometimes, some Windows Update fail to install, and just refuse to get installed on your computer even when you try a couple of times. If you face this problem where Windows Updates will not install, this tutorial will help you identify and troubleshoot the problem. Do create a system restore point first. You may then try any of these, in no particular order.
Windows Update Fail To Install
If Windows Update fail to install, is not working, updates will not download or keep failing, then these suggestions will help you troubleshoot & fix Windows Updates. Go through the entire post and then see which of these may apply to your system.
1. If you are unable to install Windows Updates, first clear up your Temporary Files and Internet Cache, reboot and try again. See if this helps resolve the issue. Best and easy to use the built-in Disk Cleanup utility or CCleaner.
2. Disable your Firewall and Anti-virus software and try again. Here is a list of Windows files and folders you may exclude from Antivirus scans.
3. As mentioned earlier, many times, an update may fail to install in the first instance, but for some inexplicable reason, succeeds in the 2nd or 3rd try. So try a couple of times.
4. Search on Microsoft, for the patch using the Update KB number, and download its stand-alone installer. Now apply the patch manually. Search for just the number; don’t include KB! Also, go here to see the Complete Master List of Windows Update Error Codes.
5. Use the Windows Update Troubleshooter from Microsoft. It resets Windows Updates settings to defaults.
6. Use our Fix WU tool and see if it helps. It re-registers all the dll, ocx and ax files required for the proper functioning of Windows Updates.
7. Fix corrupted Windows Update system files using DISM Tool or CheckSUR. Run System Update Readiness Tool. It can help fix problems that might prevent Windows Updates and Service Packs from installing.
8. Right-click Computer > Manage > Services > Stop the “Cryptographic Service” and rename the Catroot2 folder situated in C:\Windows\System32\Catroot to something else like say Catroot2X.
Now run the update or the installers again. This action will re-generate a new Catroot2 folder and the updates or hotfixes, should hopefully install.
9. If still, you have a problem then, go to C:\Windows\WindowsUpdate.log and look for the most recent entry. This will be present towards the end of the log. Any failed updates will have error code/s written next to them. Note them down. If you find just too many entries too confusing delete this WindowsUpdate.log and try installing the problematic updates again.
Now open the newly re-created WindowsUpdate log file and have a look at its contents.
The warnings will probably appear as -: WARNING: Failed to find updates with error code XXXXXXXX.
Now Right-click Computer > Manage > Event Viewer > Applications and Service Logs > Microsoft > Windows > WindowsUpdateClient > Operational . Check out for any Critical Message or Warning.
Next, refer the Windows Update Error Codes. This will give you the direction in which you may have to look for the solution.
