Regarding this Dell XPS-8930:
I recently replaced a 500gb SSD drive that was several years old & had started having Windows 10 issues.
I installed the new drive (500gb SSD) & installed a fresh copy of Windows 10. After the installation was complete
and in booting up, there is 3 options for booting: Windows 1, windows 2, windows 3. number one being the default.

After searching the internet, I found a safe way to remove windows 2 & 3 . However, I wound up having a Windows.old
file that has 23gb. of data that I cannot delete. When trying to delete, it will first say that I need administrative permission
one time and then some other permission listed under C: Users. I have tried changing the permissions & now its so screwed up
I'm not sure what the correct move would be in order to take full control of this PC. Seems Dell could be the culprit in all the problems?

Any suggestions would be appreciated............
