Windows 10 Start Menu and / or default apps broken

Sometimes, for whatever reason, the new Windows 10 Start Menu breaks, and stops responding. There are a number of articles on the web of what to do, and most are geared for standalone systems.  For Active Directory, the fix is pretty straight forward.  Log in as the domain admin, go to C:\Users and delete the account folder. Then go to regedit.msc and delete the corresponding registry key for the profile. Go Here: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList Look on the right side window pane of regedit, and find the profile name by clicking through the list, most likely the bottom one. Right click, delete. If you have folder redirection to a file server (roaming profiles), you will have to take this a step further, and delete the entry on your file server where you store your profile folders. (Make sure you have a backup of all your files before you do this.) Once the key has been removed, and corresponding profile folders on the file server are deleted, restart the desktop computer and have the user log back on. AD will push over the profile and a new registry key will be made, a new file server profile folder set will also be created. The Start Button will work again. --- - --- Now, there are other issues that can happen to Windows 10, like the default built in Apps can cease to function, or disappear completely.  There are tools now that you can use to fix these issues.  Copy Below and Paste into PowerShell ISE, name it "reinstall-preinstalledApps.ps1 # Get all the provisioned packages $Packages = (get-item 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\Applications') | Get-ChildItem # Filter the list if provided a filter $PackageFilter = $args[0] if ([string]::IsNullOrEmpty($PackageFilter)) { echo "No filter specified, attempting to re-register all provisioned apps." } else { $Packages = $Packages | where {$_.Name -like $PackageFilter}  if ($Packages -eq $null) { echo "No provisioned apps match the specified filter." exit } else { echo "Registering the provisioned apps that match $PackageFilter" } } ForEach($Package in $Packages) { # get package name & path $PackageName = $Package | Get-ItemProperty | Select-Object -ExpandProperty PSChildName $PackagePath = [System.Environment]::ExpandEnvironmentVariables(($Package | Get-ItemProperty | Select-Object -ExpandProperty Path)) # register the package  echo "Attempting to register package: $PackageName" Add-AppxPackage -register $PackagePath -DisableDevelopmentMode } ---- -
