At times, users experience trouble using Windows Update. While there are several ways to troubleshoot various Windows Update issues, if this happens frequently, it would be a good idea to reset Windows Update settings to default. This can be useful if your Windows Updates fail to Install . We have already seen how to reset Windows Update to default using the Reset Windows Update Components Tool. Our Fix WU Utility re-registers all Windows Update related dll files and resets other settings to default. But if you want to know how to manually reset each Windows Update component individually to default in Windows 10/8/7, then this post is what you are looking for.
Reset Windows Update Components in Windows 10
1] First you will need to stop the Background Intelligent Transfer, Windows Update, Cryptographic Services. The services basically allow Windows to download all files and update that are used by Automatic Windows Update and other Windows components.

It is, therefore, the best practice to disable the BITS service before proceeding.
To do so, in an elevated command prompt window, type the following commands and press Enter after you type each command.
net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc
2] Next you need to delete the qmgr*.dat files. In order to reset Windows Update components, you will need to delete the files. To do this, at a command prompt, type the following command, and then press Enter:
Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat"
