I believe that Weatherlink 6.0.3 and the very latest Win 10 update (last Tuesday Dec 12, 2017), have a conflict. After the update installed on my Surface Pro 2017, the computer entered an endless blue screen loop displaying:
Getting Windows ready
Don't turn off your computer
After about a half hour, I shut it down and did a total reset wiping it to factory settings. I added back my various programs and data including WL 6.0.3 and all seemed well until I guess I must have ran WL and later rebooted the computer. I was back to the endless loop.
So I did a program reset, but retained my data. I then did a step by step program re-install. Firefox 57, run it, and reboot, all ok. Norton Security, run it, and reboot, all ok. WL 6.0.3 and reboot, all ok. Run it and reboot, back to the blue screen endless loop.
Note the Tues update on my Surface Pro 3 with Win 8.1 and WL 6.0.3 runs ok. Right now I'm at a loss as what to do next. I did set a restore point before loading WL 6.0.3, but I'm not sure I can get to it without Windows launching. Unfortunately I'm getting to be well versed in the various blue screen computer repair options which haveen't worked.
