The most recent OS upgrades for Windows 11 have introduced two significant vulnerabilities that impede the shutdown process of your PC and hinder Remote Desktop sign-in.
The initial update for Windows 11 in 2026 has resulted in two significant problems, preventing users from completely shutting down their PCs or signing in to a device using Remote Desktop. Microsoft failed to identify two critical flaws during testing, which are so grave that the corporation has since released an emergency remedy to rectify them.
This is not the first instance in which Microsoft’s inadequate quality control has significantly affected Windows 11 PCs. The inability to shut down your PC following a recent OS upgrade represents a significant oversight by Microsoft, marking just another instance in a protracted series of updates over the past year that have resulted in substantial issues.
The out-of-band updates, KB5077744 and KB5077797, are currently accessible through Windows Update and are being deployed to all users. Upon installation, your PC should resume successful shutdowns, and Remote Desktop sign-in should function properly once more.

Devices equipped with Secure Launch may experience failures in shutting down or entering hibernation mode. This issue exclusively impacts Windows 11, version 23H2.
Additional issues that have emerged in Windows 11 over the past year include a bug that prevented Task Manager from closing upon user exit, resulting in system resources becoming locked after prolonged use, particularly if Task Manager was opened and closed multiple times within a session.
A recent update caused File Explorer to display a white screen for users in dark mode, an issue that arose from an upgrade intended to enhance dark mode on Windows 11.
An upgrade has rendered the Windows Recovery Environment inoperative, preventing users from utilizing the recovery options to restore their PCs. Such vulnerabilities seem to be emerging in the product through Windows Updates consistently, despite the business ostensibly evaluating each release with Insiders beforehand.
