Meaningful maintenance program, speeds up the PC

Since my PC was very slow, but not old enough to replace him, I have been looking for a reliable maintenance program and have ended up with TuneUp Utilities. I had the choice between versions 2014 and 2015. In the version 2015 is clearly visible that there is a 1-year license, which must be renewed annually.
When version 2014 there is neither on the packaging, even when installing an indication of a limited valid license. Since I do not want to pay each year back, I have decided for the 2014 version. Who buys this version, is based on a perpetual license.
It would be a shame if it would involve a "false fact". The program is very helpful and has solved on my PC problems that have known "full protection" -Virenprogramme not found. My PC is running again much faster. However, the year has not yet been to. We will see ....
