Windows 10: registry: can I delete it this file or folder and how do I do it

I had a nine year old gateway m-6750 lap top giving to me.It had vista on it I did a clean install of windows 7 premium Then did a clean install of windows 10. So far windows 10 is running perfect. I have been going thru ever file and folder one by one and deleting everthing I can find that had anything to do with windows 7 and so everything is going good The only thing left on this lap top is a folder called (NTUSER.DAT) I opened it and in the drop down box opened it says options I opened it and it says downloads Iclicked down loads and nothing downloaded so I went to (REGEDIT) and went to HKEY-CURRENT-USER>NTUSER.DAT. and could,nt find anything to do with ntuser, So my question is can I delete it this file or folder and how do I do it.By the way the file was created in 2009 and the new windows 10 was installed 10-27-2018.

How do I delete registry files?

I have some programs which I deleted from "Add/Remove Programs" and I want to make sure they are deleted... where do I go to delete these files in my registry?

Also, I know there is a website where you can type in the name of programs running in the registry files to check if they are legitimate... where can I check my programs?

Thanks for any help!

How do I delete registry files?

type in regedit in the search box and press enter. Then from here on, DO NOT TOUCH ANYTHING UNLESS U KNOW WHAT UR DOING!! Go to Hkey_Local_Machine > Software > Then a list of program registry keys will pop up, delete anything that is uninstalled. Make sure u backup the keys unless something goes wrong. To backup, you do: Select a group of keys on the left pane > Right click > Export > name it "whatever.reg" > save it. To import the backup, click the reg file and click "merge"
