Start menu tiles and Notification/Open Action Centre dissappeared!

Strange, my start menu left click that used to open the coloured start menu with 'tiles' has stopped working. I can only right click to access the 'grey' listing. If I do left click I see the blue spinning wheel for a couple of seconds but nothing appears.
Also the icon for 'New Notifications' has stopped as well, when clicked I used to see a slide out popup asking me if I would recommend W10 to a friend but not now. If I right click to 'Open Action Centre' nothing happens.

Any suggestions as to how to fix them?

Many thanks.

Well, looks like Search, Edge, Store and who knows what else has failed along with my start and notifications!!

Tried sfc /scannow but all seems fine. Think it's about time to go back to W7 and wait while MS gets its screwdriver and hammer out....

I also tried the methods to resolve this, powershell and others, none made any difference. As these apps are a fundamental requirement of user of W10 MS seems very quiet about these problems, they are widely reported on the MS forums!!

I thought of a new profile, but what happens when that one fails, generate another and then another? A good workaround but not an acceptable solution in my opinion.

I got so fed up I have reverted back to my stable and reliable W7, I will try W10 again in around 6 months and hope their screwdriver and hammer have sorted the problems.

I agree, Win10 seems to be really bitchy about user profiles. All the standard maintenance activities (registry cleaning, removing unused files, etc.) I did routinely in Win7 invariably seem to F'up Win10. For now, I've decided to do weekly (daily?) system images and just refrain from any system maintenance activities until things stabilize. Wish I could go exclusively Linux...

+1 - same here. Start menu worked for less than a day. I tried every solution but while one or another worked for some, nothing worked for me except adding a new user or a fresh windows install. Definitely not ready for prime time. Caveat Emptor. Went back to Windows 7.

There are two services that you can make sure are enabled here. 1) Tile Data model Server set to automatic 2) State Repository Service set to Manual.

Normally you can't change these but they are changeable in the registry. Value of 1 is automatic (Delayed), 2 is Automatic 3 is Manual 4 is Disabled.

Reg key is located here: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

Next, you'll want to reinstall all Apps through Windows Powershell as administrator:

paste this line in and see how it performs for you:

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