Profile Trasher is a Powershell script that deletes cached Windows 2016 Local User Profiles at logoff, ensuring that users get a brand new User Profile at every logon. Profile Trasher is intended for environments where a roaming User Profile Management solution is not required or when using Pseudo / Hybrid Mandatory Profiles.
Profile Trasher is intended for use on Citrix XenApp Servers running Windows 2016 Server. It could also be used on Windows 10 'Kiosk' PCs.
Problem:
- Start Menu stops working.

- Start Menu right click context menu stops working.

Cause:
When a user logs on with a Local Profile or a Template Profile, the following registry keys are created using the user SID .
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppReadiness\<SID>
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\<SID>
If you are using 'Profile Spoofing' to flag the User Profile as a 'Guest' account using a logon / logoff script, then these registry keys are not deleted along with the user profile. When the user logs onto the same Citrix XenApp server, the Windows Start Menu and other Modern apps will likely become unstable and eventually stop working.
Profile Spoofing is common when using hybrid profiles that do not require the entire user profile to roam, and a new user profile is created at each logon.
This is unlikely to be an issue when using Citrix XenDesktop because by default a desktop O/S virtual machine will reboot at logoff so the HKLM registry keys get cleaned up following the reboot. However when using Citrix XenApp each XenApp server may not reboot for a number of days therefore if a user establishes a second logon on a server where the user has previously logged on, then Start Menu issues may arise.
Solution:
Copy the TrasherV1.ps1 script to a local folder (C:\Windows) on you Master XenApp virtual machine.
Create a Scheduled Task with the following properties:
Trigger:
Action: Start a Program
Program: Powershell.exe
Argument: -ExecutionPolicy ByPass -NoProfile -File C:\Windows\TrasherV1.ps1
