Jailbreak ps3

A rollback only puts your computer back to a previously saved state. It doesn’t erase your files justs undoes updates which is only useful if new windows updates or drivers are crashing your computer. A reinstall puts your computer back to the factory fresh state and erases all you stuff. It can speed up your computer because it gets rid of anything slowing it down and goes back to the basics. Sorry if I’m getting too technical.

When defragmenting, your computer takes files and sorts them better. Like taking a bunch of papers that have been scattered across the room and putting them in order (where possible) in a neat stack making it easier to find what your looking for. Defragmenting after you install anything major, like a game, and doing it every month or so can help with the performance of your computer. You may not notice a difference unless your computer was in desperate need of a defragmentation.
