Well crap….
According to Microsoft’s support website, the security update released earlier this week (MS-045) had various issues and it could cause Windows not to boot or even blue screen in some cases.
Here’s a rundown of the issues Microsoft identified with the update:
- Known Issue 1: After you install this security update, fonts that are installed in a location other than the default fonts directory (%windir%\fonts\) cannot be changed when they are loaded into any active session. Attempts to change, replace, or delete these fonts will be blocked, and a “File in use” message will be presented.
- Known Issue 2: Microsoft is investigating behavior in which fonts do not render correctly after the updates are installed.
- Known Issue 3: Microsoft is investigating behavior in which systems may crash with a 0x50 Stop error message (bugcheck) after the updates are installed
As a result, Microsoft has stopped distributing the update through Windows Update and pulled the manual installer for their website.
On the plus side, Microsoft has provided instructions to fix the fonts issue and remove the update from your computer on the support website. You can use them to get your Surface working again if you had problems after installing the updates earlier this week.
If your Surface is running fine, I wouldn’t worry about uninstalling the update (unless it starts acting up). Our Surface Pro 3 took the updates with no problems and we’ve not seen a single problem – so take that for what it’s worth. We are not planning on uninstalling anything.
