I am having problems just registering for Windows 10 on my desktop. When I click on the W10 icon in the tray a window comes on saying please wait. It has not changed from that for quite awhile. It probably stay on for hours. This is a fairly old computer. I purchased it whn W7 came out. Bought W7 upgrade at the time. It had Vista. On my laptop, the information window came on within 30 seconds. The computer is a Falcon NW I7 core. 12 gb ram. Any suggestions? Thanks in advance.
