How to exactly “protect” a folder from Windows Media Player (preventing it from messing up album covers)

I struggle with the following two instructions mentioned on on this blog post for Windows Media Player 12 shows wrong cover art when playing

Then (separately, else you won't get the Security tab) bring up each one's properties in Explorer, and drill down to the access control list for Everybody (you might need to add one).

Well, I don't see "Everybody", how can I add this "Everybody" option?

Now in the ACL windows, tick to Deny Write for these files

Which options do I have to tick exactly? There are quite many options available (Full access, Change, Read, Run, ...)

Solution 1:

If you don't see the Everybody user, you will need to add it yourself: click Add and then type Everybody in the text field. Note that if you're running a non-English version of Windows, you will need to actually enter the translation of Everybody to the language of your system. Next, click Check Names. If the text that you entered becomes underlined then that means that it was recognized and you can click OK.

As for which options to tick, simply ticking the Write option under the Deny heading should do the trick. You can verify your changes by opening the file in WordPad (not Notepad), entering some text and trying to save. Saving should fail with an access denied error.
