Our Review Policy
All system utilities are reviewed and scored based on their effectiveness at speeding up overall computer performance and Internet access. It's very important to us (and all Windows users) that a stable Windows environment is maintained - because no one wants to tune-up their PC to higher speeds, only to have it crash.
We always have a growing list of PC optimization software to look at. Rest assured, we have evaluated most (if not all) of the popular choices. If they never made it to our list, that doesn't mean their a bad program, they just were not good enough in our opinion.
The system speedup solutions we have reviewed here, are the absolute best we have found. If anything groundbreaking makes its' way onto the scene and surpasses these programs, we'll be sure to post a review as quickly as possible. We'll even give you a head's up that something's in the works. Although it would be near impossible for any new developer to beat our top choices; and we don't see anything new on the horizon for the next while.
You have to be very careful and it's important to check if a PC optimizer is safe that are currently circulating concerning system utility software.
if you've been waiting for a while to get an optimizer, this years' leader, WiseCare 365 Pro, is the biggest leap forward in almost a decade. Highly recommended for those seeking the absolute most advanced optimization available.
