Hi Rocky,
Does your Desktop have any USB devices currently plugged in? WiFi device? External Storage device etcetera?
If it does, some users found disconnecting these devices then rebooting computer resolved the frozen login page issue. Once it has booted fully to Desktop allow time for a few more background processes to complete.
For me those background processes took around 10 minutes and at that stage the System icons I expected to see on bottom right corner of taskbar appeared and were active.
At that time you ought to be able to connect your devices and allow Windows to detect them and from then on they ought not give any further trouble.
