The description says the product comes with windows in "S" mode, however I don't care as I've got my own licensed Windows 10 license, media, and activation which I will use.  Or so I thought.I bought this piece of hardware because I expect it to work with the software I already own.I installed and activated Windows 10 Enterprise LTSC (not upgrade, but delete all partitions and install fresh)The OS comes up in "S" mode.  I didn't even know Enterprise LTSC *had* "S" mode, but a google search for this issue shows that lots of people have had the same problem with this model of Acer.Totally locked down and useless for my needs.To prove the install media was not the issue, I removed the M.2 SSD and put it in a Dell, booted linux, and nuked the drive dd if=/dev/zero of=/dev/nvme0n1 bs=4M and let it complete.  Then reinstalled Windows and activated it in the other laptop.  Everything is normal, the OS is not activated and not running in "S" mode.  Installed & ran chrome & VLC; successful.  Rebooted a couple of times, still no "S" mode.  Everything looks OK.Move the M.2 SSD from the Dell to Acer and booted.  It's in "S" mode.  According to MS this isn't even possible; once you're out of "S" mode you can't go back.  Activated Windows and rebooted; still "S" mode.Put the SSD back into the Dell--normal mode.  Put the SSD in the Acer again--"S" mode.  Repeat once more back and forth; if the SSD is in the Acer, it goes into "S" mode.Wow.  Packed it up and returned it.  Hopefully Amazon refunds; if not, I guess chargeback.
