The first Windows 11 update released by Microsoft in 2026 caused two major problems: PCs could not be completely shut down, and remote desktop logins failed.
This is not the first time that Microsoft's poor quality control has caused significant inconvenience to Windows 11 users. The fact that the update made it impossible to even turn off the PC is a major mistake by Microsoft, but it is just one more addition to the long list of update errors that have occurred over the past year.
Emergency updates KB5077744 and KB5077797 are currently being rolled out to all users through Windows Update. Installing this will restore PC shutdown and remote desktop login functionality to normal.
