I ordered an Acer to be shipped overnight.  When I checked the tracking the next day, it said it wouldn't be there until the following week.  I then ordered another one.  The original order came the next day with the 2nd computer the following day.  I set up the originally ordered computer and it continually crashed.  I got the link from Acer for the Microsoft 1809 fix, but the directions were incorrect.  It kept repairing itself and restarting.  When I put my programs on, they were wiped off to original settings of the computer.  I worked on this computer for DAYS!  I finally gave up and decided to try the other Acer that had come in.  SAME thing.  After working on TRYING repeatedly to set this computer up for 5 days, I gave up and went to Best Buy.  The computer technicians I talked to thought it might be the hard drive component that Acer is using.  I will never buy another Acer.  What a headache!
