4. Back to Normal

Another question.

Although it is only for the Internal, it would be better to clean any data after the presentation done.

So have deployed a scheduled task.

The "Program/script", because of Task Scheduler: 0x41301, requires not to run arguments directly.

It requires:

a. Program/script: C:\Windows\System32\WindowsPowerSehll\v1.0\powershell.exe

b. Add arguments (optional): -NoProfile -NoLogo -NonInteractive -ExecutionPolicy Bypass -file "C:\_bin\Cleaner.ps1"

Cleaner.ps1

Get-ChildItem C:\Users\user\Desktop -Recurse | Remove-Item -Recurse -Force

Get-ChildItem C:\Users\user\Documents -Recurse | Remove-Item -Recurse -Force

[...]

To set the task for user logoff:

a. Tab: Triggers

b. New / Edit

Last, run "bginfo" to set a Notification on the Wallpaper.

Windows 10 Pro

Replaced it by one Windows 10 Pro laptop.

Set it via Local Group Policy for Cleaner.ps1.

User Configuration —> Windows Settings —> Scripts (Logon/Logoff).
