Reset Windows Update using Command Prompt

Use these steps to manually reset Windows Update components using Command Prompt on Windows 10:

1.Open Command Prompt with admin rights.

2.Type the following commands to stop Background Intelligent Transfer Service (BITS), Windows Update, and Cryptographic (press Enter on each line):

The article uses the rmdir command to remove directories with the /S switch to delete the specified directory and all subdirectories in the main directory, the /Q switch is used to delete the directories without confirmation. If you get the message “The process cannot access the file because it is being used by another process.” (The process cannot access the file because it is being used by another process), repeat step 1 and try again, as one of the services may have suddenly restarted.
