Not sure about Mac, never used it, I assume it doesn't... Linux, nope, but Widows gets slower the longer it is on your system... Is it because the file system doesn't self defrag (Seriously MS it is almost 2017 make NTFS self defrag)... Plus, make Windows install like MacOS, just wipe & reinstall the OS files leaving the programs alone... I would love to reinstall windows & still have my programs... Or just make the registry less complicated, OMG!!! All we need is a SYSTEM tree & Data so we could atleast backup data & if our Programs were on another partition/drive, putting the backup back would be enough to have everything back...
