[@Andreas] A 391 day license is a problem? There are a lot of optimization programs that offer a one-year license like IObit’s Advanced SystemCare Pro, Iolo’s System Mechanic, and Auslogic’s Boostspeed. If you want more than a one-year program, you can try Ashampoo’s WinOptimizer 2019 or WinOptimizer 15 which have unlimited licenses. You upgrade those by getting a successor version of the program, not by renewing a license yearly.
