Windows 11 Wallpaper

We all make mistakes. But when you’re Microsoft, and you make a mistake that breaks Windows 11, it tends to get a little more attention. That’s precisely what happened when Microsoft pushed an ad to Windows 11 that broke the Start Menu and Taskbar.

What Happened To Windows 11?

Microsoft pushed a promotional notification to Windows 11 users, and one particular one that was touting Windows 11’s integration with Teams seems to have broken the Start Menu and Taskbar of the OS.

Basically, the ad would cause the Windows desktop shell to crash, which rendered two of the core functionalities of the OS unusable. In fact, it made it almost impossible to do anything with a Windows 11 PC.

Thankfully, Microsoft posted a fix for the problem, and it’s easy enough to deal with. It applies to both builds 22000.176 and 22449. Here are the steps posted by the company:

Step 1: Use CTRL-ALT-DEL and choose to open Task Manager.
Step 2: Choose “More details” at the bottom of Task Manager to expand Task Manager.
Step 3: Go to “File” and choose “Run new task”.
Step 4: Type “cmd” in the “Open” field.
Step 5: Paste the following (everything in bold):
reg delete HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\IrisService /f && shutdown -r -t 0
Step 6: Hit enter, and then your PC should reboot. After rebooting, everything should be back to normal.

While it’s a bit of pain, at least Microsoft was quick to get a fix out. Hopefully, these promoted notifications don’t cause future issues for Windows 11, especially after it launches on October 5.
