> Windows 11 update KB5074109 is breaking systems — Microsoft says uninstall it ASAP. Here's how.
I had it paused, chatgpt.com to avoid installing it:
✅ The fix: remove the cached update, then hide it properly
Step 1: Delete the downloaded update files
This forces Windows to “forget” KB5074109 so it becomes hide-able again.
Pause updates (keep them paused for now)
Open Command Prompt (Admin)
Run these commands one by one:
net stop wuauserv
net stop bits
Open File Explorer and go to:
C:\Windows\SoftwareDistribution
Delete everything inside that folder
(not the folder itself — just the contents)
Go back to Command Prompt and run:
net start wuauserv
net start bits
Reboot
Step 2: Hide the correct KB
Now run wushowhide.diagcab again:
Click Hide updates
You should now see KB5074109 listed
Check it → Finish
✔️ This time, it’s actually blocked.
✅ Step 3: Prevent re-download shenanigans (Pro-only)
You already have Pro, so lock it down a bit:
Group Policy hardening
Win + R → gpedit.msc
Go to:
Computer Configuration → Administrative Templates →
Windows Components → Windows Update
Set these:
Configure Automatic Updates
Enabled
Option 2 – Notify for download and auto install
Get updates for other Microsoft products
Disabled (optional, but reduces noise)
Then:
gpupdate /force
Reboot once.
