Action center not working.

Following on from the recent success with the windows search indexing options not working Windows search indexing options is missing. I thought I'd also tackle another fault with the action center which I've just noticed is also not working.

On my recently updated Win 11 Pro build 26100 and fully up to date machine if I click the clock it whirls but then doesn't launch the Action Center.

I can right click on the clock to adjust the time or go to notifications settings and that works.


I've run the usual sfc and dism checkhealth and no problems have been found.

In regedit

HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Explorer the key DisableNotificationCenter=0

and the following doesn't exist

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Explorer

Can anyone suggest where to look next?

Hello again Ollie, :alien:

You can see if running the command below in an elevated PowerShell to re-register all apps (including the Notification Center), and restart the computer when the command finishes may fix it.

Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

I've just tried that and it runs through but there are a lot of errors due to some files not being modifiable as they are in use and others where the installed version is later than the one it's trying to install. Apologies for the poor formatting.

That's ok. It's normal for those unable to re-register.

Was it able to help fix the Notification Center (Win+N)?

Sorry I forgot to say that, sadly no it hasn't.

Win + N or clicking the clock you can see it trying to start something and then it just fails.

In the event viewer it shows an application error

Let's try running the command below in an elevated PowerShell. It does the same as the command above, but is applied to all users instead of just current user. Restart the computer when the command finishes. It'll be normal to get a few error messages for apps it can't re-register.

Code:
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Sadly that has not fixed it either.

One change I have noticed is that if I hover the mouse over the clock then a small popup with the time and date appears which I don't think it did previously.

OK, the action center appears to have burst into life which wasn't working previously.

Clicking the wifi or battery icon now makes it burst into life as it should so again we look to have success with this part.

What still does not appear to work is the notifications and calendar that used to appear when I click on the clock or press Win + N, any other thoughts on that?

Good news so far.

Clicking the wifi or battery icon would normally open Quick Settings (Win+A) instead.

Just to confirm, does it look like the Calendar is just collapsed in the Notification Center like below, or not there at all?

If I click on the clock I get nothing other than the the cursor spinning very briefly and the error in the event viewer.

If I hover I get the small popup.

Ok. Quick Settings will now open, but Notification Center still not opening.

I know you don't have the "DisableNotificationCenter" DWORD, but just as a test to see if this may toggle (refresh) the Notification Center, use option 1 with the all users policy location below to fully disable the Notification Center, then enable it again afterwards.

So when I enable that setting clicking on the clock does nothing and there are also no errors in the event viewer.

Disabling it or setting it to not configured again goes back to the previous action of not working but causing an error in the event viewer.

Ok. One more thing to try.

Boot into Safe Mode, and sign in to an admin account other than your account with the Notification Center not working in.


Delete everything inside the folder below, and boot back into your account. This is to clear the database files in case of corruption.

C:\Users\<your account profile folder name>\AppData\Local\Microsoft\Windows\Notifications

I can't easily get it into safe mode without the bitlocker rescue key which I don't have hand and would ideally prefer not to mess with.

However signed in as another admin user account I can delete the files you mentioned. I also note that the notification window works perfectly as doe the windows spotlight image on the other admin users lock screen but not my usual account.

Then when I sign in with my usual account if I click on the clock as soon as the desktop appears then the notification window appear however after about another 15 seconds it no longer works and won't do so until those files are deleted again.

I do have a few start up programs so I suppose the first thing to do is to disable those, delete the notification database files again and then see if it works.

Well, it seems like it's trying to work for a bit.

Hopefully, it'll work after disabling the startup apps and trying again. I don't think it'll make any difference though.

Since it does work in the other account, you could create a new account to use instead of your current one if it came down to it.

With all start up apps disabled the machine starts faster and as such there is now no period where it works, presumably it's getting to whatever is stopping it working faster than before.

Clearly it looks like the problem is related to the user account and you're right that a new account would probably fix things however this is quite heavily used as a software dev machine and I've got all sorts of things setup that will need transferring to make it work so I'd rather avoid that if possible.

I'll have a look through the services to see what can be disabled and again see if that makes any difference.

Ollie, it looks like you have a corrupted user profile.
Sooner or later, the corruption will get worse (it never gets better) and then where will you be?
Please consider doing a backup and then begin setting up a new user profile.

Since it's trying to work now, you could try running the commands again to re-register it to see if it may work afterwards.

As OAT posted, it may be time to prepare for a new account.

I fear you and OAT are going to be correct, with a few oddities going on it does make sense to switch.
