Windows 2019 Active Directory

Hello, I am creating a GPO for users in the domain, I will activate system restore with the startup script and allocate 20% disk space, but the script does not work.

systemrestoreenable.ps1

Enable-ComputerRestore -Drive "C:"

vssadmin resize shadowstorage /on=C: /For=C: /Maxsize=20%

When I run the script with administrator privileges, it works, but when I apply it to GPO and computer accounts as startup, it does not work.

I also tried with -ExecutionPolicy Bypass commands, I tried adding task scheduler but it doesn't work
