2-3 weeks ago my Windows 10 did an update that caused 100 % CPU (Quad Core 3.8ghz). Probably not the best today but 5 years ago it was decent lol. It was using 100 % CPU and 11GB or 12GB of RAM. I noticed that despite my saving files to external Hard drives I had 450GB of 1.3TiB of HDD space. I formatted and decided to go back to Windows 8 (8.1 after all the updates). So much better than Windows 10.

Anyone else have issues with Windows 10?

My Windows 10 was behaving like Windows Millennium Edition and would not release system resources. Use to use 20-40 % when running games. Now it just pointless to use Windows 10. At least now I can have 100 windows of IE open and only use 800MB of memory instead of 9GB. I am always using 15-20 % CPU now and 3500GB of RAM max in Task Manager.

Windows 10 is the biggest mistake ever. I am surprised I survived 3 years with it. Back on 8/8.1 and it just feels so much better. 8/8.1 is far superior than 10. Why would Microsoft update it with such bad resource management? Hopefully 8 and 8.1 won't let me down.
