I have Dell Precision M6400, with an 5400rpm hdd, and Core 2 Extreme QX9300 processor, due to some drivers support and issues i cannot move to linux, i was experiencing many issues so have to go back to Windows and windows 10. I use win 10 debloater from Christitustech from github, by which i used tweak settings, remove cortana, remove apps, and turned of search engine indexing for drives, i also defragmented and also made its effects to performance, but still i see no change in speed of startup and applications loading time i see experience freezes, slow time and unresponsive behavior but in linux it was quiet good. i also have enough ram for my normal works its 6gbs divided in 3 sticks. i only have browser work or watching videos. What else thing i can do to gain performance other then upgrading to ssd? or changing machine? if there is any possible way to trim windows more?
