Still working on this. Hope to up my rating if we can get things working. First experience with the system was very positive. Issue is that on day two I saw a message in the lower right corner of the screen: "Go to settings to Activate Windows". Settings says "We can't activate Windows on this device because you don't have a valid digital license or product key. If you think you have a valid license or key, select Troubleshoot below. Troubleshooter says "Something interrupted our troubleshooting." Called Acer support and was told they would mail me Windows Installation USB memory stick. Waited a little over one week and asked for status update. Was told that USB install media was not available, and I should contact Microsoft for activation. Entered last four digits from activation error message and was told I would need a new product key. Contacted Acer support again, and was told we would need to return the computer to the factory for fix; which could take 15-20 business days, plus shipping time. Briefly considered returning to Amazon, be decided to try the Acer service option. Will be awhile before we get it back.
