Recently, Windows Insiders in the Dev and Beta channels began reporting that Start and Taskbar were unresponsive and that Settings and other areas of the operating system were not loading. Don't panic, there is a solution to this issue. I will describe (step by step), the process of fixing this Windows issue.
If you were affected by this issue, you can follow the steps below to return to a working state on your computer.
Step 1: Use CTRL-ALT-DEL and choose to open the Task Manager.
Step 2: Choose "More Details" at the bottom of the Task Manager to expand the Task Manager.
Step 3: Go to "File" and choose "Run New Task".
Step 4: Type "Regedit" in the "Open" field. Note: From this step forward, you will be very careful. Any error, entry, or deletion of any of those registries or records can make your computer malfunction worse than it is.
Step 5: Using the registry editor browsing window, you will find the following address: HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\IrisService. HKCU stand for Hive Key (HK) Current User (CU)
Step 6: Once you find the IrisService folder, left-click on the IrisService folder and choose Delete.
Step 7: When you are asked if you want to delete this key and subkeys, you will choose yes. After deletion…
Step 8: Restart your computer. After restarting, everything should return to normal.
