Resetting Windows 10 NTFS Disk Dirty Flag

This is basically taken from this, however, it seems like Windows 10 marks dirty disks differently (which is still unlisted there). After fiddling around with DMDE, I managed to find the dirty flag by myself.

Disclaimer: DON'T try to do this if you don't know what you're doing. I won't be responsible if your HDD becomes corrupted after doing this. Proceed at your own risk.

1. Get DMDE GUI.
2. Run it
3. Click on "Logical Disks", and select the drive that has the dirty flag, and click OK
4. Click the logical disk volume, then click "open volume"
5. Press Alt+C, when a dialog box pops up hit enter
6. Press Ctrl+S, then on the "Hex" text box, type "03 01 01 02 00 00 00 00 80 00 00 00 18" (without quotes), then click OK.
7. The search should be very quick, and you should see the hex string you searched instantaneously. However, if it takes too long, proceed to step 9. Otherwise skip to step 8.
8. Press Ctrl+E, then change the string "03 01 01 02" to "03 01 00 00", then click Ctrl+W, then click Yes, then close DMDE. fsutil dirty query check should now tell you that the disk isn't dirty.
9. If the search takes too long, cancel it. After canceling, press Ctrl+S, type "03 01 81 02 00 00 00 00 80 00 00 00 18" (without quotes) and then click OK. But if it takes too long again, proceed to step 11. Otherwise skip to step 10.
10. Press Ctrl+E, then change the string "03 01 81 02" to "03 01 00 00", then click Ctrl+W, then click Yes, then close DMDE. fsutil dirty query check should now tell you that the disk isn't dirty.
11. Again, if the search takes too long, cancel it. After canceling, press Ctrl+S, type "03 01 01 01 00 00 00 00 80 00 00 00 18" (without quotes) and then click OK. If it takes too long again then probably you have a different dirty flag that I haven't found yet, and you're probably out of luck for now.
12. Press Ctrl+E, then change the string "03 01 01 01" to "03 01 00 00", then click Ctrl+W, then click Yes, then close DMDE. fsutil dirty query check should now tell you that the disk isn't dirty.

If the drive is locked, then you're probably trying to modify a drive that's currently in use. If so, then use Hiren's Boot CD and reset the dirty flag using the steps mentioned here. I haven't tested it yet, so I'm not sure if it will work.
