The wuauserv service, also known as the Windows Update service, is a critical component of the Windows operating system. It is responsible for detecting, downloading, and installing updates for Windows and other Microsoft software. Keeping your system up-to-date is crucial for security, performance, and stability. This article will guide you through managing and troubleshooting the wuauserv service using various methods, including the Command Prompt (CMD) and PowerShell.

   Look for the STATE line in the output. If it says RUNNING, the service is active.

3. Starting and Stopping wuauserv via PowerShell:

5. Troubleshooting Common Issues:

   • Issue: Windows Update service is not starting.

     Solution:

     sc config wuauserv start= auto
     net start wuauserv

     This command sets the service to start automatically and then attempts to start it.

   • Issue: Windows Update is stuck or failing.

     Solution:

     net stop wuauserv
     net stop bits
     ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
     net start bits
     net start wuauserv

     This sequence stops the Windows Update and Background Intelligent Transfer Service (BITS), renames the SoftwareDistribution folder (which stores update files), and then restarts the services. This can resolve issues related to corrupted update files.
