Bad Microsoft update bricks computers
Software is a complex thing and sometimes when you fix a certain software bug, you create a new one. Even large software companies, such as Microsoft, are not immune against bugs in their products so no matter what they do, there are bugs coming our way. Just ask owners of PCs that run Windows 7 and use ASUS motherboards – these configurations have suffered major problems in the past few days due to a botched update that comes out of Microsoft.
The update is called KB3133977 and fixes a bug in the KB2990184 update but creates a situation, in which computers, based on Windows 7 and ASUS motherboards cannot boot Windows anymore. Users of such machines get a message that says that unauthorized changes on the firmware, OS or UEFI drivers have been detected. Fortunately there’s a way to go around the problem – just enter the UEFI BIOS menu and then go to Advanced Mode Menu –Boot – Secure Boot and in the OS Type window you must select Other OS, which deactivates the UEFI mode of loading Windows. Another way to deal with the issue is to simply remove the broken KB3133977 update but this means that you have to boot a different OS and then delete the patch from Windows 7.
Microsoft has not commented on the issue but a new patch that, hopefully, will solve this problem should be on the way.
