Hello, I upgraded a Windows 8.1 Pro Sony Vaio laptop to 10 Pro yesterday. The biggest issue I have is I would say 19 out of 20 boot ups (or wake from sleeps), instead of showing the lock screen with the user name to enter your password and sign in, I just get a solid blue screen with spinning circles.
When booting up it also says Please Wait... under the spinning circles. But after a little bit the term Please Wait disappears. At that point if I click CTRL+ALT+DEL I see our Companies Acceptable Use Statement (this is a domain joined machine so all machines get this pre-login message). I click OK on this message just like I would in Win 7 or 8 and then instead of seeing my lock screen background with the field for user name and password, I see the blue windows background which I guess I would call the default background if its not an upgrade. There are three icons in the lower right corner. One lets me adjust wifi connectivity / airplane mode, one is an access button for the narrator, and the last button is to power off or reboot.
Without any fields to type in my user name, I cannot proceed any further with the PC booting. I'm not entirely sure how I get booted on, I usually have to restart a whole bunch of times until it shows my mountain background with the time in the corner and I click a button, it slides up and reveals the username and password field.
Now I see it sat at that default windows background screen for a bit while I type this on a desktop PC and eventually I'll say the laptop "timed out" and went back to a blue screen with spinning dots. I hit CTRL+ALT+DEL and the domain's acceptable use policy came back up. Clicked OK and then it went right back to spinning dots. I can hit CTRL+ALT+DEL again and the acceptable use policy comes back up, but as soon as I hit OK, it just reverts to spinning circles. Now I have no choice but to hold the power button down for 10 seconds so it cold boots. I'll have to do this repeated times until I can finally get a lock screen that allows me to log into the computer.
For the record I have a desktop PC that I upgraded from Windows 8.1 and it was flawless. Everything works on it without an issue. This laptop appeared to mostly work, except for IE 11 not launching and this logon screen. I just wanted to remove IE 11, reboot and then re-add it as suggested in another post, and now it will be a few hours of reboot retries just to get back to the desktop, only to have to redo it all over again when I readd IE 11 (surely it will ask for a reboot).
