A friend of mine bought a new laptop with an ssd and called me over since it behaved weirdly. All the icons on the desktop would turn to white squares and slowly reload their images. Also the laptop was pretty slow.
She said she had brought it to the store to show that behaviour and the only advice they would give was to reinstall windows...
So I started checking on what processes are running...
The thing was constantly running an "optimization" tool... which, you guessed it, was constantly defragmentating... the ssd... are you fkn serious who set up that shit this way...
