The KMS Pico Tool, a portable activator for Windows 10/11, is posted on GitHub Gist. Features: requires no installation, leaves no traces in the registry, activation takes 10-30 seconds, works offline. Supports Windows 7, 8, 8.1, 10, 11 ( all builds up to 24H2). The size is ~37.7 MB. The description honestly says that antiviruses can swear — these are false positives because the program modifies system files. The author also mentions that from a legal point of view, this is a gray area. For those who need to activate the system quickly, this is a working tool, but use it at their own risk.
