iCloud pop-up at every Windows 11 startup

I've had this exact issue after a recent update

I'd like to follow-up. What I finally did tonight was uninstall iCloud for Windows and iCloud for Outlook from my Windows 11 laptop. I tried numerous other "fixes" which didn't work. I apologize that I cannot provide details, but I do recall this: 1) I removed all iCloud apps from StartUp in Settings/Apps. I removed iCloud apps from Task Manager (not just End Task, but removed from StartUp in Task Manager), and I even used a Command Prompt function (with several other drill-downs) which I found online. None of those things worked.

Not that I'm a favorite of either platform - Windows vs. iOs - but frankly, even after all these years, they do not play nice together in the sandbox. I'm trading in my iPhone for a Samsung and will be done with it! (Going all Apple is not an option.)

I know you may not wish to remove the Apple apps, but that's the only option I saw & tried online which worked for me. I'm happy with it.

Try signing out of iCloud, then signing in. That fixed it for me. I found that solution in other thread.

When I attempt to sign out, I'm warned that this will delete all photos and videos stored in iCloud will be deleted from the PC. I suspect that, like most folks that is several thousand photos - a pretty scary proposition - but I bite the bullet and proceed only to be informed that

and, I'm not signed out.

However, a further annoyance has bee added. When I open Outlook, I have two additional screens to navigate that tell me

and then

obviously really old files that have nothing to do with the curent problem.

I have exactly the same issue.

Version 15.3.152

That does not even work. You can not sign out! This level of iCloud is really broken. Come on Apple fix it already.

no setting to control it.

Seems, the working solutiuon is there: iCloud on windows keeps opening non stop - Apple Community

I am also having this issue, and it is annoying. It almost feels like they don't care or do this purposefully to force you to change systems.

Try this Registry key: HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\

Microsoft\Windows\CurrentVersion\AppModel\SystemAppData\

AppleInc.iCloud_nzyj5cx40ttqa\iCloudHomeStartupTask

and UserEnabledStartupOnce = 0 for no startup

This worked for me. I checked registry entries before/after and did not see anything different. Not sure what is reset during the process of logging out, rebooting, logging in, but iCloud now starts in the background again.

Does not work for me. There is some sort of error related to outlook though I do not even have outlook installed. It erases data when you sign out but you never are actually signed out. Rebooting rebuilds what was erased but in the end you have the same problem. How about done fixes from Apple? Why does this happen and what is wrong with sign out?

You can try updating your iCloud software to the latest version. Sometimes, updates can resolve such issues with startup pop-ups. If that doesn't work, you could try reaching out to Apple support for further assistance.

Okay I think it’s finally fixed on my desktop PC. I had to sign out but let it keep the calendar and contacts otherwise it tries to communicate with outlook which I uninstalled. I then reboot and sign in. I then did another restart to prove the window no longer pops up. Note this is a highly disruptive process because sign out removes thumbnails for all if your iCloud Photos. This problem really should have never occurred and I sure hope it does not return in future iCloud versions.
