I have a XPS 8500 with Windows7 Pro. I wanted to upgrade to Windows 10, but it seems that Dell will no longer support me and the computer any longer. Dell will not support Windows 10. Well, this is not what you have promised in the past. For the past few years my wife and I have bought Dell computers. What has happened to the partnership between what Microsoft does and Dell supports. Shame on you for this. Now, I know why you are having problems in sales ... beginning to have the same face as HP. If you do NOT place Dell on the support list for Windows10, then I will NO linger support Dell in the very near future.
You can take that to the bank.
