Even if you don't play the games,we all need to squeeze as much out of PC, and gamers always have to upgrade and follow patches. That is why gaming on PC can be a pain in the backside. It is much better than it used to be and more standardized. Getting games like Duke Nukem 3D to run you required to know IRQ, DMA number for your sound card what make it was. Absolutely crazy.
I did not use the PC 5 years for the primary gaming machine because of compatibility and irritation. Just want to plug in and play, so to speak. Much easier now.
For me it is a good learning tool.Those programs will just get you spotting any rogue services happening in background to, as you start to recognize what happens behind your back.
