[SOLVED] Windows 10 Pro - Stuck on installing KB5051974 (error 0x800f0831)

[buttercookie42]

After starting up again a Windows 10 Pro laptop I hadn't used in a while, it installed the January updates fine, but then got stuck on installing the February 2025 update (KB5051974) with error 0x800f0831.

Hi and welcome to Sysnative,

Step 1. Download

SFCFix and save it to your desktop.

Warning: This fix was written specifically for this system. Do not run this fix on another system.

• Save any work you have open, and close all programs.
• Download the attachment SFCFix.zip and save it to your desktop.
• Drag the SFCFix.zip file over the SFCFix.exe executable and release it.

• SFCFix will launch, let it complete.
• Once done, a file will appear on your desktop, called SFCFix.txt.
• Post the logfile (SFCFix.txt) as attachment in your next reply.

Step 2. Run the following DISM command and post the result. If it fails attach a new copy of the CBS log.

DISM /online /cleanup-image /RestoreHealth

Cheers, SFCFix and DISM have complete successfully, but Windows Update still gets stuck, albeit with a different error now (0x80073701).

Download the
