A. It has microsoft edge which is an absolutely terrible operating system.B. It takes a full minute to minute and a half to open files if you have more than 1 page open, despite having 8 GB's of RAM.C. It doesn't have a wifi modem.D. Can't wake it up at times. It takes 10 minutes to reboot from sleep. Other times it says it can't find the hard drive.Update: Have had this sad excuse for a pc for less than 2 months and have gone back to the old pcI intended to replace when I made this terrible purchase. This thing is absolute j-u-n-k. I'm throwing it in the dumpster and will never purchase any computer related items from Amazon again.The reviews in here are a bit of a mystery. 4 stars for a product you returned for poor performance? That makes no sense???
