Windows Security won't open on Windows 11
TayDean It's early 2024 and I am in the same boat since the most recent update. In all their wisdom, Microsoft has removed Troubleshooter with this update and wants me to contact tech support. The last time I did that, I was 77 people away from help. I do not have that kind of time.
I've tried all the suggestions here except reinstalling Windows, which is a major hassle and would require hunting down the software I use for work and reinstalling it too. I had to do this once last week because a previous update crashed my computer. It created all manner of work-related issues.
This is really dumb and Microsoft should have fixed this already. But I'm open to more suggestions.
MaryPaddock i did a fresh installation and it was working all right but right after i updating the problem was back
so i am sure they have a bug
Microsoft should do something about it.
i need to disable it to be able to run a software but now i cant because, though i don't see the windows defender it still working in the background
- I currently am updated to the latest 2024-01 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5034123). And the thing is, other apps that are system installed already are not opening just like the windows security. calculator, calendar, clock, etc. They wont open.
- Hold on. You need to dowload a specific file due to the recent update messing it up. Let me get the link.
I've found a workaround for this.
Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
Type the above command into Windows Powershell (as admin) and once it shows that the command os executed (should be instant), restart your device and your Windows Security should work now.
The only issue is that you'll have to redo this once you shutdown your device (at least in my case) MaryPaddock
- It works but after some days issue again comes.. what to do
salmamlik0 I had same issue with following symptoms:
1. Restart always work for a while.
2. After shutdown a few cycles(quick start is enabled, therefore it is Kernel hibernate cycle), the issue will come back.
I have followed all kind suggestions like, reinstall security health, sfc, APP reset etc to no avail.
What fixed my issue: The other day I saw my network profile was set to public for home WiFi, after I changed it from public to private, the issue has not come back yet, finger crossed that it won't come back in a few days.
this did the trick. thank you.
EDIT: i didn't even need to restart
ShahbazUbaid I appreciate the suggestion, but it didn't work. I'd actually tried it already along with a host of other suggestions found in other places, but thought I'd missed something. I did not.
I'm fairly sure I'm going to have to reinstall Windows again to fix this. It will have to wait until the weekend as I work full-time from home and this has eaten up far too much of my time as it is.
Exceedingly frustrating.I am in the same boat after the lastest update. I've tried everything, including factory reset (twice). Still locked out.MaryPaddock
