Please clarify the following:

Are you getting an error code? If yes, which one?

If you don't get an error code, see the update history.

• Press "Windows + I" and select "Windows Update > Update history".

If you prefer, share a screenshot. Use the shortcut "Windows + Shift + S" to use the screenshot tool.

Also. What is the current "OS Build" of your Windows 11?

• Press "Windows + R", type winver, and click OK.

If you prefer, share a screenshot.

Be sure to censor your email address if it appears. The Microsoft Q&A is public.

Many factors can cause this error. To avoid a long answer, I will suggest a few procedures. If these do not work, there are other methods.

I suggest doing the following:

---

Run the Windows Update troubleshooter and try to install the update.

If it persists, rename the software distribution folders as instructed below:

1. Open Start and type cmd, right-click on "Command Prompt", and select "Run as administrator".
2. Run the following commands at the Command Prompt one at a time:

net stop bits
net stop wuauserv
net stop cryptsvc
ren %systemroot%\softwaredistribution softwaredistribution.bak
ren %systemroot%\system32\catroot2 catroot2.bak
net start bits
net start wuauserv
net start cryptsvc

3. After all these commands are completed, close the Command Prompt window, restart your computer, and then try to update Windows.

If it persists, use the system file checker to repair possible corrupted or missing system files.

1. Open Start and type cmd, right-click on "Command Prompt", and select "Run as administrator".
2. Run the following commands at the Command Prompt one at a time:

dism.exe /online /cleanup-image /scanhealth
dism.exe /online /cleanup-image /restorehealth
dism.exe /online /cleanup-image /startcomponentcleanup
sfc /scannow

Note: Pay close attention to the results of the commands. This will help you determine whether the procedure was completed successfully or if there was a problem. If you get any errors, let me know the error message that was displayed.

3. Then restart your PC and see if you can update.

If it persists, download and install the update that is having problems manually.
