I've worked with multiple IDEARACE Industrial PCs over the past two years.  I've been happy with how they perform for the tasks I'm using them for.  They've all been good at doing what I need them to do.  Unfortunately, they've transitioned from Windows 10 Professional to Windows 11 Professional.  With this change, I've experienced a few more challenges.  In this case, I've experienced an issue where Windows 11 Professional will not activate.Attempts to contact the seller or manufacturer through Amazon were beyond frustrating.  It took me talking to a third representative before I finally received a phone number I can call.  Amazon Customer Support let me down on the first two, disconnecting me before I could respond to their third repeat of "Contact the manufacturer" but giving me no way to.I've finally received a contact number for the Manufacturer and will be working with them on resolving the issue later today (once they've opened).  Overall, I'd be wary of ordering this model again.Updated 8/2 - The contact number did not work… go figure. However, I was able to send them a message through Amazon. I received a response from IdeaRace via Amazon Messages for my request for assistance within 24 hours. They provided an updated key that allowed the system to properly activate. The system is running and operating as expected now without any issue. I’ve adjusted from 1 star to 4 stars, but had to keep the fifth star off because of the original issue.Updated recommendation: This is a nice little industrial PC that I will continue to use moving forward.
