Microsoft has issued a warning about a new serious Windows 7 problem that is very real even though it makes no sense. Microsoft has made a seemingly small yet completely bizarre tweak to Windows Update on Windows 7 and confirmed it is crippling many users’ PCs.
It switched the status of Windows 7 update KB3133977 from ‘Optional’ to ‘Recommended’. The bizarre part? Despite acknowledging the problems, Microsoft knew they would occur in advance and it has no plans to do anything about it.
PCs That Suddenly Won’t Start
It all centres around Asus motherboards. Asus Recently enabled Secure Boot in UEFI on all its motherboards. This wasn’t a problem for older PCs because Windows 7 didn’t support Secure Boot, that is until KB3133977 came along in March and enabled it.
Initially the fallout was small. Asus confirmed the problem, Microsoft confirmed the problem. But the best news was KB3133977 was an optional Windows 7 update so it had to be manually installed to take effect. The solution was simple: just steer clear of KB3133977 (aka do nothing) and you’d be fine.
Then last month – for some bizarre reason – Microsoft made KB3133977 a ‘Recommended’ update. The result was every user running Windows 7 and default Windows Update settings (the vast majority) would find the update now installed automatically.
And then everyone with an Asus motherboard was hit.
A Global Problem
As InfoWorld’s Windows expert Woody Leonhard notes “I’m now seeing problems reported from all over the globe about Windows 7 machines that suddenly won’t boot”. Affected machines simply show a red box which says:
All of which does nothing to pinpoint the problem or solve it for those without a second secured boot device. In short: you’d be screwed.
The Good News And Staying Safe
The good news is Asus has now issued a workaround to get PCs booting up again. Furthermore Asus must take some of the blame for not reacting faster when KB3133977 presented a potential landmine and issuing new updates to its motherboards.
How do you know if you have an Asus motherboard in your Windows 7 PC? Go to: All Programs > Accessories > System Tools and select System Information. This will list your PC’s components, including the motherboard.
One downside: some major PC makers like Dell and HP rebrand the motherboard as the computer’s model number. In which case you should do a web search on your model or call the manufacturer directly.
The Bad News And What Comes Next
As for the bad news? It’s Microsoft’s reaction.
On the plus side, Microsoft did update the support document for KB3133977 with a warning which states: “After you install update 3133977 on a Windows 7 x64-based system that includes an Asus-based main board, the system does not start”.
But Microsoft also uses the document an opportunity to promote upgrades to Windows 10:
Microsoft has also done nothing to modify KB3133977 or release a new patch so users with Asus motherboards don’t run into this problem in the first place. Furthermore, at the time of publishing, KB3133977 remains a ‘Recommended’ in Windows Update for Windows 7.
Regardless, the message is clear: life is going to become increasingly uncomfortable for Windows 7 users from now on. Whether they like it or not.
