You can either download the executable and run it as root, or make a virtual python environment with script.py, zstandard and requests installed then run the python script as root. Unfortunately, there's one Windows NVRAM variable that is not removable via software, called "CurrentPolicy". I don't know what the hell it is for - to me it's just Microsoft spray painting that it was here on your firmware. You will need to change a few bytes on your firmware's NVRAM (via hardware programmer like CH341A) to delete it. It's created even if you just boot the Windows boot manager (bootmgfw.efi), without a kernel and without accepting the EULA. It errors with "Security Violation" if you attempt to delete it, as it requires cryptographic authentication that I don't know where you could get (probably only Microsoft has the keys). I heard it's for security but I think that is a lie. However it shouldn't be that bad as its content is only a few bytes and won't affect your Linux system. For executable: chmod +x executable sudo ./executable For virtual environment python: (make sure python3.12-venv is installed, install with sudo apt install python3.12-venv) python3 -m venv windows_nvramvars_cleaner cd windows_nvramvars_cleaner bin/pip install zstandard requests (paste the script.py in the new folder and you can rename it to main.py) sudo bin/python3 main.py
