Windows 11 update KB5074109 is proving to be an utter disaster for Microsoft, as the patch is leaving some users unable to boot into the operating system. The problem stems from new security updates, with seemingly no fix for the issue other than to enter recovery mode and revert the changes outright.
According to Ask Woody, Microsoft has received a “limited number of reports” of PCs unable to boot with stop code “UNMOUNTABLE_BOOT_VOLUME”, after installing KB5074109. This code describes problems with the Windows 11 file system, typically pointing to corruption or damage, but can also indicate a failing piece of storage.
In the case of KB5074109, the error is usually reversible via System Restore or other recovery methods. However, until users take such action, their systems will continuously fail startup, and will instead go through a bothersome boot loop.
This is the most serious issue that can come part and parcel with KB5074109, but it isn’t the only one. The Windows 11 update was also causing application failures, and made it impossible to shut down PCs in some cases. Thankfully, Microsoft has already deployed hotfixes for those problems.
One can’t help but feel like the path Windows 11 walks is forever bumpy, with prior patches reducing gaming performance, and entire cumulative updates such as 24H2 becoming a complete mess. It’s no wonder that many were so desperate to cling on to Windows 10 via prolonged support schemes, which Microsoft failed to deliver in a bug-free manner.
I’ve used Windows 11 since launch, and I’ve been lucky enough to escape any serious errors. However, I can’t help but feel that it’ll be a case of when, rather than if, a single or horde of bugs comes to ruin my day. If Microsoft is serious about providing better game optimisation and quality assurance to the OS, the brand would do well to get its act together sooner rather than later.
Like many, I’m patiently awaiting the arrival of Valve’s Steam Machine. While I know there are already plenty of Linux distros out there that would serve me, and many others, well in place of Windows, it should hopefully serve as a welcoming entry point for the operating system. Perhaps too welcoming, should Microsoft not greatly improve the current standing of Windows 11 in the eyes of gamers and plenty of consumers too.
