If i press the up arrow in powershell the last command shows up. Other programs delete this "history" but it seems like powershell doesn't. I would like to know how to remove this data ( a restart doesn't work ).

Using the command Clear-History "deletes the command history from a PowerShell session."

PowerShell's Clear-History doesn't clear history

"[Microsoft.PowerShell.PSConsoleReadLine]::ClearHistory() can be used to clear the current session's history"

  • I tested this, it won't work. Clear-History PowerShell's own history mechanism (Get-History, Clear-History) is host-independent, which is why - somewhat unexpectedly - you also need to clear the hosts's command history separately. --> https://stackoverflow.com/questions/13257775/powershells-clear-history-doesnt-clear-history – Nicicalu Mar 12 '20 at 11:57

You can clear this history by pressing Alt + F7. This is the most simple way, without a command.

Edit: Thanks to Midacts for pointing out the command for this purpose:

[Microsoft.PowerShell.PSConsoleReadLine]::ClearHistory()
