how to delete  

Thank you very much for your reply.

. I don't know what you mean by "Do you have admin permission." I have no idea.

Google is very helpful to explain things. Try asking it the right question.

E.g.
https://support.microsoft.com/en-gb/...-administrator

Look here in Settings, Accounts: you can see my account is an administrator account.


Still unsure? You can consult the tutorial section here. See this to find out:
Determine Account Type in Windows 10

Sorry to be awkward but what do you mean by "does it not let me uninstal"?

1 Do you mean that they are not listed as installed and therefore cannot be selected in the list?

2 Do you mean that you can select them in the list but you get an admin challenge for you to confirm the action before it lets you proceed? That is normal -
- Even an Admin user account is initially logged in with Standard user account authority.
- The admin prompt ["ConsentUI"] that you see is used to invoke your admin authority for that job only.
- When you need to do your next job that requires admin authority, you will get prompted to confirm that before it goes ahead because the confirmation only lasts for the one job each time.
- That's how Windows is designed.
- The idea if that admin authority must be invoked before any action is carried out that could affect other user accounts on the computer. A standard user account can only make changes that affect that standard user account.

3 If you can select them in the list but the problem is not that you get an admin challenge for you to confirm the action before it lets you proceed, please post a screenshot / photo of the dialog that is stopping you.

This is a normal admin prompt [ConsentUI] as seen by an admin user account


This is a normal admin prompt as seen by a standard user account [in which case it is an "ElevationUI"]


There is one type of fault condition in which the admin prompt appears with a broken Yes button [it is either greyed out or missing]

And if you ever see this you can use the solution in Fix UAC prompt has greyed out or missing Yes button - TenForumsTutorials

These are old versions of WMP, mail etc left over from Windows 7 and before, and are not in C but in another drive. I don't know what you mean by "Do you have admin permission." I have no idea.

Do you mean, these files are not part of your current system, but just leftowers? You'll have to take ownership of that folder and files (they are part of other system)

Tutorial | Change Owner of File, Folder, Drive, or Registry Key in Windows 10

If you are unfamiliar with command prompt etc, I would recommend using application (like dachina sugested above), or adding "take ownership" to your context menu - so you can right click on folder in explorer..

Add Take Ownership to Context Menu in Windows 10

Be careful not to do it on your system folder (C:) - like it is pointed out in tutorials.

Just download .reg file from that tutorial and run it. (Follow instructions in that Tutorial.
