    Show Known File Extensions Reverts to Default


    Hello all,

    I hope this isn't a repeat thread - I didn't find any others that were having this issue.

    On the first day I received my laptop, I went into folder options and selected to show hidden folders and show known file extensions just as I have in 7, and Vista before that.

    It seems like every few times I log back into my PC, this option has changed itself and decided to hide all file extensions. The showing hidden folders option has not changed back once.

    Very strange! I thought it was a registry scan that was reverting the option, but it doesn't seem to be causing the issue.

    Any ideas?

    Hello TheDailyToker,

    You may have unchecked the File name extensions option by mistake in the ribbon in File Explorer as below. It's a global setting, and not just for that folder.

    Hope this helps,

    Thanks for the reply, Brink!

    Unfortunately, I have not been able to check this out yet because my hard drive has since crashed. I just got my machine back up and running today, so we'll see if it goes off again and I'll double check myself

    Howdy!

    Well, it happened again. The only things I have done is create a system restore point, install Adobe Reader and also a UNIX to print program for work. Is it possible that Adobe altered these settings upon installation? I work with the folder ribbon up now, so it wouldn't be a slip of the cursor.. Very curious!

    I shouldn't be doing any more installations for some time, so if it reverts I'll take note of what I did, or dig through event viewer if it comes down to it...

    Today is the 2nd Tuesday Windows Update day, so it may be possible that one of the updates reset the settings. ??

    Ah! That makes more sense to me than Adobe going in there. I completely forgot about that.. the Windows update snuck in on me when I did a quick warm boot. This hasn't tweaked your settings, though?

    It didn't change mine.

    If you use Microsoft account and have another PC with extensions off, such behavior may be a result of File Explorer settings synchronization. See Win+W - sync
