Windows 10: Switch C: drive with D: drive and move Program Files

I have a desktop HP computer tha has a C: drive SSD of 237 GB . Windows 10 is loaded there and by default all Program File and Program Data. The other drive D: is a Hard drive with 931 GB. C: is almost full. How do I move all the Program Files etc to D: and only leave C: only for Windows and then set up the system so that all future Programs load in the D: drive.

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

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

Something like this

 

Boot error INACCESSIBLE_BOOT_DEVICE, drive letters C: and D: switched

Hi,

Thanks for the reply. I did as suggested, but it did not solve the problem.

Not sure from which drive I'm supposed to execute the commands and if this matters at all. When entering command prompt mode, I was on drive X: and can change to C: and D:, I executed first on C:, then on D:, with same result:

BOOTREC /FIXMBR -> process completed

BOOTREC /FIXBOOT -> access denied

BOOTREC /scanos -> 0 Windows installations found

BOOTREC /rebuildbcd -> 0 Windows installations found

As indicated in my original post, drive letters C: (was originally the SSD with Windows and program installations) and D: (was originally the HDD holding data) have somehow switched. When I go to C: in command prompt and execute DIR, it shows me all the
content that was supposed to be on D: and vice versa.

That means, I can find the Windows directory that was supposed on C: under drive letter D: now, which might be a symptom of the issue, or the root cause.

So might it help to switch back drive letters C: and D:, and how can this be done?

Thanks and regards.
