Now we will clear the Windows Update temporary cache folder:
Hold down the Windows key while pressing the “R” key.
A small new window will appear.
Enter %Windir% \ SoftwareDistribution \ DataStore in this new window and press OK. 4 This will open Windows Explorer in the right place.
5. Delete all the contents of this folder. (Note: use Ctrl + A to select all files and folders).
Run the DISM tool
The Deployment Image Management Tool is a built-in Windows command-line tool used to manage Windows system images. It often solves problems with Windows, from small ones like this, to more serious ones you may encounter. It is quite easy to do, but follow the instructions carefully, as failure can do more harm than good.
Simultaneously press the Windows key and the X key on your keyboard. From the menu select Command Line (Administrator).
Press the Windows key and type. Right-click the result and select “Run as administrator”.
Once you have opened the command line in one of the two ways described above, you need to enter the following commands. Be sure to press Enter on your keyboard after each keystroke to execute them and prevent any typing mistakes.
Type exit and press Enter or just close the command line window.
Try to start the Windows Update Center again. Updates should now work correctly.
The final solution
In this case you will have to work very hard to reinstall the Windows operating system.
Backing up your data is the most important thing so that you do not lose your personal files.
