Microsoft has confirmed that some users might find their PC unable to boot after installing the January 2026 security update released on January 13. This is on top of the plethora of other issues that have been reported since Microsoft's disastrous Patch Tuesday updates arrived.
So far, the company has released two emergency out-of-band updates for Windows 11 to address major bugs that were introduced with this month's security updates, but this latest issue that is causing PCs to fail to boot has not yet been addressed.
