C: Drive and D: Drive files switched after upgrade

Sorry, didn't exactly know where to post this.

So recently I had my Windows Vista upgraded to Windows 10 (also upgraded various hardware).
Today I was fiddling around and customizing it, when I noticed that all of my files that were previously saved on my C: Drive were now on my D: drive, like my Program Files and, well, basically everything I ever downloaded.
Should I be worried? I've heard that things like Program files are MEANT to be on the C: Drive, whereas the D: drive is meant for windows files...

Please post a couple of screenshots of file explorer open at your c and d drives.

Something like this

All of my downloaded programs are located in the D: Drive

The default is to have the OS on C:, and program files there as well. 64 bit programs go in Program Files, and 32 bit ones in Program Files (X86).

The mess that you have now may be partly related to it not being allowed to upgrade Vista to Windows 10. Your new 10 installation is in the default location. Whoever installed 10 should have tidied things up for you.

Looks like you have Windows 10 on C: and Vista on D: (going by the dates of the folders shown).

Make sure you check that Windows 10 is Activated as not doing an upgrade means it will not activate is it's the free version from Microsoft.

Right clik on This PC and go to the bottom of the window.

Thank you to both of you for replying.

Ztruker, I did as you said, and went to the Properties of This PC and it said that Windows is activated, though I'm still not clear on what that means.

Now that I understand the situation better, can someone tell me the necessary steps to fix it? Should I transfer all of my program files/files that are on D: to C: ?

You want Windows to be activated. Win 10 will run for a time without activation, but I don't know for how long.

It's not easy to move program files if they were installed. (Installed programs make entries in the Windows Registry. Experts can move them; I can't.) Do the programs still run at all?

When I say, "move," I mean copy program files from D: to C:, then possibly delete the D: drive original copy.

No, when I try to access programs located in D: from the file explorer, they simply fail to open. No process appears in the task manager, nothing. However, programs I re-downloaded on Windows 10 are able to use program files from the D:/Vista drive just fine.

Should I just reinstall all programs I want/need on Windows 10? Should I leave the Vista side alone... or should I clean it all up?
