There are lots of fake official KMSPico programs available over the internet on different platforms, and they all have different passwords. You must turn off all the anti-virus programs and Windows security protection before you try to extract the setup file.
That’s why its setup file is compressed and password protected as well. Windows OS is smart enough to detect it and delete it, even if it is compressed in a simple zip format.
When the real-time protection is turned ON, Windows deletes the downloaded file immediately. Windows 10 and Windows 11 firewall treats the KMSPico program as a virus. This tool is password protected to save it from deletion by Windows Firewall or any other antivirus program. Use as a zip password to extract the setup file.
