Fix 2 – Rename the Software Distribution folder

Step 3 – Now, this is the most important step. Copy these lines from this page and paste them on your terminal. Then, push the Enter button once.

ren %systemroot%\softwaredistribution softwaredistribution.bak
ren %systemroot%\system32\catroot2 catroot2.bak

This way, you can rename the SoftwareDistribution and Catroot folders.
