Windows 10: Still unable to delete old system files

A while ago I moved to using an SSD as my main boot drive but kept my HDD as storage. I didn't want to wipe it so all of the old windows files are still on the drive. I have tried taking ownership of the files and also running the takeown command in an admin command prompt. It worked, but now the files are unable to be deleted without administrator permission even though I am the only user and admin on this computer. Program files and Program Files x86 are taking up a lot of space and I want to free it up. How can I actually delete these files?

Unable to delete temporary files

Hi Sumit,

Looks like you are running out of storage space, let's walk you through the steps of running
Disc cleanup for your Windows 10 device.

To delete temporary files, kindly follow these steps:

• Press the Windows key to launch the Start menu.
• Type in Disc cleanup and press Enter.
• Under Files to delete, select the file types to get rid of. To get a description of the file type, select it.
• Select OK.

If you need to free up more space, you can also delete system files:

• Press the Windows key to launch the Start menu.
• Type in Disc cleanup and press Enter.
• In Disk cleanup, select Clean up system files.
• Select the file types to get rid of. To get a description of the file type, select it.
• Select OK.

If the suggestions above didn't work, feel free to post back so we can further troubleshoot.

 

How to delete inactive System Image Restore Points in System Restore

Windows 10 64-bit.
When I click "show more restore points" in System Restore I see a bunch of old "system image restore points" that were deleted in past and do not correspond to any currently active restore points. Clicking any of these old restore points, I simply get an error message saying they could not be found, and to select another restore point instead.I would like to delete these restore points listings but have been unable to do so.
So far, I have tried steps mentioned below without any luck :

Disk Cleanup through (C Properties
Disable System Protection (OFF and ON) in System Protection for OS (C
Disk Space Usage to minimum (slider button all the way to the left then 'Delete all restore points for this drive'),
Delete all shown Restore points in CCleaner (the problem ones do not show here),
Reset Windows Backup to Default in Windows 10 with 'Reset_Windows_Backup.bat' utility.

Any suggestions highly welcome.
