[The Nasdaq tanked 2.21% today, led by an 11% crash in Microsoft over high AI spending. Did it tank over high AI spending or is it because of the "update"?]
‘Crashing' Microsoft Issues Critical Warning For Windows Users
Jan 29 2026
Microsoft has now confirmed that PCs are crashing into the new, darker black screen of death following January’s mandatory security update. The good news is that the crashes are preventable. The bad news is that the underlying issue is not.
Microsoft now says, “this issue can occur on devices that failed to install the December 2025 security update and were left in an improper state after rolling back the update.” That means, “attempting to install Windows updates while in this improper state could result in the device being unable to boot.” Thus this latest January jinx.
“We are working on a partial resolution that will prevent additional devices from resulting in a no-boot scenario if they try to install an update while in this improper state,” Microsoft says. “However, this partial resolution will not prevent devices from getting into the improper state in the first place.”
