There is currently an issue that has/is impacting many Windows based devices on-campus. This issue is currently being worked on and the issue has been fixed on some devices.
If you are getting a Blue Screen error on Windows, click the "Restart my PC" option and wait for it to restart. As long as the Windows device is not stuck on a blue error screen, a normal reboot of the operating system will sufficiently apply the software patch. If it comes up as it should after a restart, you needn’t do anything further.
If you receive the blue screen error again, the following steps can be used to workaround this issue.
There are 2 workaround options. If you feel comfortable using command propmt, please skip to the Command Prompt Fix section of this article for a faster fix to this issue. If you do not feel comfortable using command prompt on your computer, please follow the instructions in the Safe Mode Fix section below.
