Why am I getting a Windows 0x800f0805 Update error?

Question

Answer 1

Hello,

Please run Windows Update troubleshooter from Settings app > Update & security > Troubleshoot > Additional troubleshooters. See if it works.

If that doesn't work, try this:

Open administrative Command Prompt and type following commands one-by-one followed by Enter key.

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

Ren C:\Windows\System32\catroot2 Catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

Close Command Prompt and see if Windows Updates works then.

Let us know if this helps!

Hi,

Error code 0x800f0805 usually means a Windows Update failure caused by corrupted system files, missing Component-Based Servicing registry entries, or a failed feature update like 21H2 or 22H2.

1. In the search bar, type Winver and hit Enter.

Please share a screenshot of that window.

2. Could you list the troubleshooting steps you've tried to avoid repeating them, if any?
