Why all the freezeing, programs, even just opening a folder

[ALS]

Dell XPS 9100 intel i7 3.47 x990 12 gig ram 2 Tb hard drive 1.4Tb free space Radeon R380 /4gb ram. RST not working, but it is running in services. The whole system has gotten very slow. I am talking about just Windows 10. My programs work fine, if I can get one to start before it freezes. Mouse sometime it will work, but not other times. I have to just pull the plug to get unfrozen.

Have you tried clean booting your system and running it that way for a day or two to see if it exhibits any improvement?

Use the steps for 8 / 8.1 same for 10
Easily done and just as easily undone. You're just disabling all startup items and all non-Microsoft services. Don't mess with the Microsoft services. Check the box to hide them before proceeding to disable all.
You may also want to take the time to Optimize / Defrag that hard drive a couple times manually, with a cold boot in between
