Usually when I click on a mp3 file it will show all the informations about that file in the bottom of the folder and I can edit them, like album, contributing artists, and track number. But recently when I clicked on them there are no tags for me to view. I have k-lite codec pack 10.4 installed.
Check if you have (accidently) written V2.4 tags - WE cannot deal with this version. Save them as V2.3 tags (See File>Options>Mpeg for that).
Copy and save the tags with the functions of the file list context menu in MP3tag.
I hope, you do realize that this looks a lot like a problem of your local settings and has nothing to dowith the mp3 tagging process. Windows Explorer is no tagging program, Mp3tag is - and as that works fine, why bother about WE?
Anyway: check if you are the owner of those files - "Administrators" does not look right to me.
Did you import that folder from an old XP installation? Then you should claim ownership again.
See this thread for a Microsoft support page on changing the owner. mp3tag on windows 7
Perhaps this one: you can set the "layout" for folders when you have a look at the properties (still, that does not explain why the properties dialogue of a file does not show the tag).
Or try the freeware "mp3val" and check the files ...
Or to put it yet another way: if your tags are allright, they have the right version and the filesystem is ok then everything should be fine. So be thorough about these checks.
