@UngameableYT if you had to rename opera.exe, that means something was blocking Opera. It’s most likely a Microsoft Family issue where you have to allow opera.exe, but it could be your anti-virus blocking Opera.
The downside of renaming opera.exe is that you’ll break DRM-protected content. This means Netflix for example will break.
Another downside is that when Opera updates, you’ll have to delete your renamed opera.exe and rename the new version of opera.exe. Otherwise, Opera won’t start.
So, if possible, it’s best to sort out the root cause so you don’t have to rename opera.exe.
