I’ve used kms auto to activate multiple versions of Windows and Office on my older and newer PCs. What impressed me is its compatibility; I could activate everything from Windows 7 to 10, as well as Office 2013 to 2021. The tool is portable, and that’s a huge plus since I didn’t have to install anything additional. It’s an all-in-one solution that is incredibly helpful if you have different systems to maintain. This activator is a great resource for anyone with varied Microsoft software.
