It works with Windows Vista, Win 7 and Win 8, regardless of their service packs. The application doesn't need to be installed, so you only need to extract and run an executable. the best part is that it takes a single click to back up or restore the activation.
It can back up the operating system's activated state and restore it after you reinstall it. Advanced Tokens Manager can relieve you from this activation process, which is particularly useful if you can't activate a product with the same key more than once. Now you can install the operating system and activate it later. Losing the operating system's product key is not as serious as it was a few years ago.
