Windows 11 version bêta

Microsoft quickly discovered an issue with a server-side deployment that went out to Insiders and canceled that deployment. If you were impacted by this issue, you can use the following steps to get back into a working state on your PC.

The issues affect Windows 11 Insider Preview Build 22000.176 for the Beta channel and Release Preview channel. They're all important visual elements of Windows that have been given a major revamp in Windows 11 amid Microsoft's decision to shelve Windows 10X – its would-be answer to Chrome OS.   

Microsoft has now provided a workaround albeit involving six steps that general Windows users might struggle with. However, most Windows users will wait for general availability in October. 

• 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.
