Hi Peet,
Could you confirm how you tried to erase corrupted libraries?
If I intended on doing that myself this is the process I'd take:
- In search box type services | then press Enter
- Click "name" column to reverse its alphabetical order
- Locate Windows Media Player Network Sharing Service | if it was running then:
- right click this | select stop
- Next press Winkey + R to open the Run Dialog
- Type: %localappdata%\Microsoft | then click OK (or press the Enter key)
- Next scroll down and right click the Windows Media folder | select Delete
- Note: This will delete all media content and ratings too
- Next open Windows Media Player.
- This will automatically rebuild the Library and any media you have ought to be added to it.
So is this how you did it? If not that may be why your attempts so far have not worked.
Another option before going through the above steps is with Windows Media Player open:
- Either press Alt | select tools > Apply media information changes
- Or click Manage | then click on Apply media information changes
This may force an auto-refresh and in essence take what you have done up to now and actually apply the change; which thus may update your Library. Worth a shot before the more drastic method above.
Re the tag change you mentioned. Sorry but I've not run into this issue before so I cannot think of anything to remedy that off hand. Hopefully, someone else in the forum may have an idea on that issue.
Edit: Probably teaching a duck to paddle here but this Dummies site shows how to edit files in WMP 12 to simulate tagging:

Also this blogger created a plug-in for WMP 12 to allow advanced tagging on certain file formats. While it does not mention mp3's it might be worth you time contacting the blogger with that issue as he may know how to fix that. His site is here:

Note: I have no idea whether that plug-in is Windows 10 compatible so you might want to check with him first on that too, should you consider trying it out.
