Update for Windows Security platform - KB5007651 (Version 1.0.2109.27002)

I had Norton 360 running, and based on prior responses I disabled Auto-protect, and then the update successfully installed.

Similar experience here. Having fixed a missing Windows Security problem (another ridiculous bug), and the update has disappeared, and isn't in the installed update lists. Much against my better judgement, I've run WU several times more, to see if it reappears, but no sign of it; a bit like a response or answer from Microsoft.

Hi all, just to let you know I got this to work.

• I do not have windows defender, so couldn't do the reset
• I installed the update helper suggested in the first page but it did nothing as far as I can tell
• I switched off my kaspersky but it still kept saying failing
• I changed the settings in the Windows Update Advanced to also pull Microsoft Office Updates and it pulled about 15 updates.
• It still said fail on KB5007651.
• I restarted, to load in all my new office updates. I'm up to date and it says I have installed KB5007651 

Thanks all

I ran the commands you mentioned each in turn on a Windows 11 laptop, the only hit being sfc /scannow said it found errors and fixed them. After restarting the pc and running Updates again, it no longer finds Update for Windows Security platform - KB5007651 (Version 1.0.2109.27002).

What's going on? Some of my systems install this update without a hitch, some fail, and some never list it in installed updates search results.

I also hided this update.
