However, if you’re a technical savvy person, you can try these steps if you’re familiar with them:
1. As soon as you click Start, start typing “services.msc” onto your keyboard.
2. There should be a result for “services.msc” in your search results. You can open it by clicking on it.
3. It will open a new window containing a list of all Windows services that are currently running on your computer.
4. In the search box, type in “Windows Update”
5. Then, right-click the “Windows Update” and then click the “Stop” button on the menu that appears.
It is now time to clean the temporary cache folder for Windows Update:
1. Hold down the windows key while pressing the “R” key at the same time.
2. The new window will appear in a small size.
3. In the new window that appears, type %windir%/SoftwareDistribution/DataStore and click on the OK button.
4. As a result, Windows Explorer will open at the correct location on the computer.
5. It is recommended that you delete all the contents of this folder. It is a good idea to use Ctrl + A in order to select all of the files and folders in a folder.

If the problem still persists, you can run the System File Checker (SFC) utility. This handy in-built tool will check your filesystem. 
1. Start typing “cmd” on your keyboard after clicking Start.
2. A black icon should appear in your search results for cmd.

6. Enter sfc/scannow.
7. It will take a long time to complete this process. This black window can be minimized and you can work on it.
Check the black window after a while to see if the process has completed.
