After upgrading to W10, why is my PC so slow?

[Windows Central Question]

after upgrading to W10 slow PC

everything runs fast only my screen freezes sometimes and same with typing i noticed that i only 10% of my CPU after disabeling Speed stepping ( for intel) i got more CPU and it fixes the issues. so my question is is there an issue with intel drivers and W10 ? i have the latest drivrs installed. its kind of important because we are planning to uprgade more of the same PC's to W10

Re: after upgrading to W10 slow PC

First, I wouldn't assume the problems on one will be visited on the others just because you're having trouble on one computer.
Second, it would be hard for anyone to diagnose your computer problems not knowing its chipset, age of the hard drive, video ram or whatever software configuration you had prior to your upgrade. A lot of variables to contend with. What I do know is Windows is very memory intensive and if there is any issues with memory anywhere, Windows will find them for you.
Try doing a restore to previous OS, make sure there is drive space and try upgrade again.
