Option 4 – Flush the contents of the SoftwareDistribution folder
You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush the contents in the SoftwareDistribution folder.

As a result, the next time you run the Windows Update, it may result in a longer detection time.
- Open the WinX Menu.

- Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauserv
net start cryptSvc

- Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
- Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.
net start wuauserv
net start bits
