Windows 10: Windows 10 Start Menu and Apps Stopped Working, Can't System Restore

Hi, my Windows 10 menu was working previously, but then certain apps started not opening and they had an exclamation mark next to them, so I looked that up on Google and came to a page that suggested entering this into Powershell:
Code: Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}[/quote] So I did that, and now Windows Start menu won't open at all.

I tried system restoring back to a known good installation which would have fixed both issues, but it doesn't work. After a reboot it informs me:
Code: System Restore failed while restoring the directory from the restore point. Source: AppxStaging Destination: %ProgramFiles%\WindowsApps An unspecified error occurred during System Restore. (0x80070091)[/quote] So then I read something about renaming the WindowsApps folder in Program Files after taking ownership and granting permissions. I attempt that, renaming WindowsApps to WindowsApps.old, but I get a black screen on Windows Startup, so I can only access System Restore from Recovery. It still doesn't work due to an unspecified error, so I have to rename WindowsApps back to its original name so I can get back into Windows and... the start menu still won't work and I have numerous Event Log errors such as:

Code: Unable to start a DCOM Server: Microsoft.Windows.Cortana_1.10.7.17134_neutral_neutral_cw5n1h2txyewy!CortanaUI as Unavailable/Unavailable. The error: "5" Happened while starting this command: "C:\Windows\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy\SearchUI.exe" -ServerName:CortanaUI.AppXa50dqqa5gqv4a428c9y1jjw7m3btvepj.mca[/quote] I have a drive clone, but it only goes back to pre-Spring Update so I don't want to use it if I don't have to.

WINDOWS 10 START MENU and SEARCH STOPPED WORKING - FIXED all -- BUT APPS DISAPPEARED...

• AUG 24, 2015:
• START MENU and SEARCH stopped working --(AND many items on the task bar disappeared or stopped working). Also the apps were no longer accessible.
• To fix, I tried all the fixes suggested by MS support that I found in the answers to others with the same problem--but none of it worked.
• I FIXED THE PROBLEM by using RESTORE ...(YAY!!!)... and restored my system to the state it was in before the last update I had received.
• It took forever.. (I went to bed and let it run overnight) BUT IT WORKED! EVERYTHING IS WORKING: start menu, search, etc. etc. Everything was back and working except for the APPS... no apps appeared in the start menu and the 'app store' icon was still
  missing from the task bar.
• After all was restored, I did a Windows 10 UPDATE, to get back the updates that were removed when i did a system restore--everything worked out fine!
• HOWEVER, all the APPS were still missing
  from the start menu and the MS APP STORE icon is still missing from the task bar.
• BUT I am able to add apps back to the computer (and to the start menu) one by one.
• ...... Anyone know of a way to restore all the apps to my computer and restore the "Store" icon back to my task bar?

 

Windows 10 Start Menu and Some Apps Stopped Working - Can't System Restore

Hi, my Windows 10 menu was working previously, but then certain apps started not opening and they had an exclamation mark next to them, so I looked that up on Google and came to a page that suggested entering this into Powershell:

Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

So I did that, and now Windows Start menu won't open at all.

I tried system restoring back to a known good installation which would have fixed both issues, but it doesn't work. After a reboot it informs me:

System Restore failed while restoring the directory from the restore point.

Source: AppxStaging

Destination: %ProgramFiles%\WindowsApps

An unspecified error occurred during System Restore. (0x80070091)

So then I read something about renaming the WindowsApps folder in Program Files after taking ownership and granting permissions. I attempt that, renaming WindowsApps to WindowsApps.old, but I get a black screen on Windows Startup, so I can only access System
Restore from Recovery. It still doesn't work due to an unspecified error, so I have to rename WindowsApps back to its original name so I can get back into Windows and... the start menu still won't work and I have numerous Event Log errors such as:

Unable to start a DCOM Server: Microsoft.Windows.Cortana_1.10.7.17134_neutral_neutral_cw5n1h2txyewy!CortanaUI as Unavailable/Unavailable. The error:

"5"

Happened while starting this command:

"C:\Windows\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy\SearchUI.exe" -ServerName:CortanaUI.AppXa50dqqa5gqv4a428c9y1jjw7m3btvepj.mca

Another symptom is that the task bar is on top of every application, even borderless fullscreen games.

I have a drive clone, but it only goes back to pre-Spring Update so I don't want to use it if I don't have to.
