Hydration errors, such as 0x800f0993, are slightly difficult to fix.

Launch Settings > System > Recovery. Under "Fix problems using Windows Update", select Reinstall now.

This performs a repair installation while keeping your files, apps, and settings.

Hello,

Please run Windows Update troubleshooter from Settings app > System > 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!

There was no additional troubleshooters option.

Repair the Windows component store with DISM and SFC, restart, and then retry KB5132061; Microsoft has not documented error 0x800f0993 as a known issue with this update.^1^

Repair Windows and retry

Open Start, type Command Prompt, right-click it, and select Run as administrator.
Run these commands separately, waiting for each to finish:

DISM.exe /Online /Cleanup-Image /RestoreHealth
sfc /scannow

Restart the computer.
Open Settings → Windows Update → Check for updates, then retry KB5132061.

DISM repairs the Windows image and SFC checks protected system files. Microsoft specifically documents this sequence for Windows Update corruption and installation failures.^2^

If it still fails

Use Windows 11’s built-in repair reinstall. This reinstalls the same Windows version while preserving installed applications, personal files, and settings:

Back up important personal files as a precaution.
Keep the PC connected to power and the internet.
Open Settings → System → Recovery.
Under Fix problems using Windows Update, select Reinstall now.
Select OK, allow the repair installation to complete, and restart.

This is the safest non-destructive fallback for update failures involving Windows system files or components.^3^

Check the KB5132061 prerequisites if repair fails

The screenshot’s build 26300 identifies Windows 11 version 26H2. KB5132061 requires:

A Windows update released on or after September 22, 2026, such as KB5124010.
Servicing Stack Update version 26100.9539 or later.^1^

To display the installed servicing-stack version, run this in an administrator Command Prompt:

DISM /Online /Get-Packages | findstr /i "ServicingStack"

The returned Package Identity should show version 26100.9539 or later. If it is older, install all earlier updates offered under Settings → Windows Update, restart, and check again before retrying KB5132061.
