    There is a typo
    Computer > HKEY_CLASSES_USER > Software > Microsoft > Windows > CurrentVersion > Explorer.
    should read
    Computer > HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Explorer.

      Hi, Peter! Thanks for your advice!
      I will ask my colleague to send you a Driver Easy license key.
      Have a nice day!

    There is no HKEY_CLASSES_USER in my regedit. There is HKEY_CURRENT_USER, HKEY_CLASSES_ROOT, HKEY_USERS. Tried current_user which seems to correspond to your suggestion, but no luck.

    OMG My Alt-Tab function was working but STICKING. I had to alt-tab,
    then release both and hit alt again to get it to switch (You have NO
    IDEA how irritating this was!) I went to the recommended registry
    section and the regkey did not exist. I created it as recommended and
    it seems to have totally fixed my issue!!! THANK you so much!
