Hi PowerPnt-Like-3984,

This is a Windows Update error. Please do the following in order to resolve:

1. Click Start and start typing on your keyboard for "services.msc"
2. In your search results "services.msc" should show up. Open it with a click.
3. A new windows will open containing all Windows services on your system.
4. Search for "Windows Update"
5. Right-click the "Windows Update" and then click Stop.

Now let's clean the Windows Update temporary cache folder:

1. Hold windows-key and hit "R" key together.
2. A small new windows will appear.
3. Type %windir%\SoftwareDistribution\DataStore in this new window and click OK.
4. This will open Windows Explorer on the correct location.
5. Delete all contents of this folder. (Hint: Use Ctrl + A to select all files and folders)

Now we will start the Windows Update Service again:

1. Switch back to the windows Services.
2. Locate Windows Update.
3. Right-click on it and choose Start.

If the problem still persists, you can run the System File Checker (SFC) utility. This handy in-built tool will check your filesystem.

1. Click Start and start typing on your keyboard for "cmd".
2. In your search results cmd should show up with an black icon.
3. Right-click it and select Run as administrator.
4. If you are prompted for the admin password, enter the password and click OK.
5. A new completely black windwos will open. You can type commands directly into this window.
6. Type sfc/scannow and press Enter.
7. This process will take a long time. You can minimize this black windows and work on.

I hope this answers your question.
