- You press the Start key (or open the Start menu) and you type something expecting to filter items
- Instead nothing happens
- You click on the Windows 11 search textbox in the Start menu, but it takes no input
- You get notifications in the tray bar, but if you click on them, like on Windows Updates, it doesn't open Windows Updates
I searched and searched. No, it wasn't running ctfmon. No, it wasn't restarting anything. No, I didn't want to reinstall Windows all over again.
What it was was removing/renaming the IrisService Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\IrisService registry entry and restarting the computer. I thank Tech Advisor for this, although the problem wasn't that there were no answers on the net, but that there were too many and the vast majority of them were wrong and inept.
Searching further, with the solution in hand, I found this little link: Windows 11 bug, so it is indeed an issue coming from Microsoft itself (probably update KB5006050). That should probably teach me against installing optional updates on my computer.
The funny thing is that after I did this, I restored the original values of the registry entry and it didn't have any effect. What is this IrisService? No one seems to know for sure.
Well, hope it helps!
