Open a elevated command prompt and type in the following two lines, and press Enter after each:

net stop wuauserv
net stop bits

Each command should take a few seconds, so wait until you see the messages that the services were stopped successfully. Leave the command prompt open for now.



Navigate to C:WindowsSoftwareDistribution and open the folder. Press CTRL + A to select all files and folder, then press the Delete key. All the files in the SoftwareDistribution should be deleted. We don't want to delete the folder itself.

Rebooting will start the two services we stopped, but if you don't want to reboot, open up the command prompt again and type in the following two lines, and press Enter after each:

net start wuauserv
net start bits
