Windows 10: How do I set my C:/ drive exclusively as the OS drive, with other file/programs on D:/ ..?

I have a desktop PC running Windows 10 for work. Mostly used from graphics and design work, occasionally web browsing.

It has two HDD, Windows C drive at 118GB and the Local D drive at 931GB

I only have 3.8GB spare on the C:/ but there is 899GB spare on the D:/

I want to use C:/ as the OS drive only and have all of the programs stored/installed on D:/

I'd also like to store things like Documents, Downloads, etc. as well as the local copy of our Google Drive on D

Is there way of doing this that is relatively easy? I have a good degree of knowledge in using the PC but would rather utilise a piece of software to do the legwork for me.

Spec of PC is:

AMD Ryzen 5 1600 Six Core Processor 3.2GHx 16 GB RAM 64 bit OS X64 based processor Windows Home 10 Version 1809 OS build 17763.914

C:/ 118GB (3.8GB free) D:/ 931GB (899GB free)

Thanks in advance for any help anyone can offer.

edit: Just to point out, C and D are separate physical disks, not virtual drives on the same disk.

sfc copied C:\Program Files to D: drive

Okay, so here's a little background information:

I have Windows 10 installed on an SSD that is not large enough to hold all of my installed software. So, I have another D: drive where I install all 3rd party programs. I went into regedit > HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion and
changed ProgramFilesDir & ProgramFilesDir (x86) to point to D:\Program Files & D:\Program Files (x86), respectively.

Now, I have been having problems over the last few days with Windows Update installing (KB3081444). After exhausting several options, I decided to run
sfc /scannow, in an attempt to solve whatever problem Windows Update is having. Well, this led to sfc basically duplicating all of the Windows C:\Program Files & C:\Program Files (x86) to my D: drive.

I neither want nor need these files on my D: drive, but I cannot delete them because it tells me I need permission from TrustedInstaller.

I'm not really sure what to do here (most of my experience has been in Linux), but I would like to remove these files from my D: drive and somehow point sfc to run this operation on C: rather than D:.

Any help would be appreciated, and let me know if you need more info from me.

Thanks.

Hi,

Based on the details you have provided us, it appears that there might be some corrupted contents on the said partition. We can also consider that this is caused by a virus.

• Type-in the following command:
  
  attrib -h -r -s /s /d D:\*.*

If you think that there is nothing important stored in it, then we suggest that you reformat your D drive so that you can use the free space for important files.

You can follow the steps below to start with the process:
