Instead of displaying Computer or This PC it opens a web browser and heads to computer.com WTF is that all about?
what versions are you all on. Win10 PRO opens "This PC" and Win10 LTSB opens "This PC" here. maybe there is a common denominator to determine why it isn't working for you few. Maybe you all used the same tweak, setting, or something?
You have all installed and set as default your browser Fires**t Firefox. This sometimes happens in pervious versions of Windows as well.
Very weird, maybe it's something in the applications tab of FF own settings, where it decides what to do with certain requests / file types Then again, Windows would have to send that request to FF in the first place..
