Hi @Brink

I have installed multi "Chrome" themes and "Microsoft Edge" native themes on my latest stable version (Edge v88.0.705.56). How can I uninstall them?!

There is no theme section in "Settings". I have removed one theme that appeared in "Settings>Appearance". I know the others (themes) are hidden somewhere! As I realized they are hidden in "AppData\Local\Microsoft\Edge\User Data\Default" but I don't know where exactly they are and how to uninstall them!

You should be able to use option 2 below to remove a theme in Microsoft Edge.

Didn't work! BTW I ruined my "Preferences" file in Edge's default user profile folder!! … I reset my "Preferences".

Is "WindowsQ" a new "Windows" forum? I didn't meet it before you mention above! My apologies for irrelevant question.

Oops on the reset.

… There is a file next to the original one (Preferences) in "AppData\Local\Microsoft\Edge\User Data\Default" with "bad" extension (Preferences.bad). As I realized (by checking the file date and time modification) it's the old one that Edge has archived. Is that safe to remove it?

Did you have a Remove option available for the theme?

Yes and I have removed just one theme which was available there (but I had installed multi themes from Chrome and Microsoft Edge extension page)

Brink said:

Usually, when you change the theme in Microsoft Edge, it will replace and remove the previous one by default. I'm not sure yet if the theme is kept saved anywhere though.

I thought the Edge will remove the previous theme by installing new theme but when I go to a specific Chrome theme page (that I installed it), a yellow bar notification on top of the page says "Your theme is disabled! Enable it by click here" and when I click on, it enable again (previously installed Chrome theme)!

Correct. Windows Questions is a new site we're working on.

Another URL added to my "Favorites"

What happened to www.windowsq.com btw?
Just say this post, tried to go that site, it is not up

Thank you Brink!
Yes, I guess individual sites make sense.
Good on you guys for listening to the forum users!
