iCloud pop-up at every Windows 11 startup

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.

Y'all can stop responding to me now. :) Logout and login work like a charm. Filing for future reference.

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.

Same here except I no longer have outlook. I use Edison mail instead. I did have iCloud integrated with outlook at one time. The way ai got around that was to keep the contacts and calendar. Then it seems like iCloud deinstall does not try to go out to outlook.

Its been happening to me for the past month. Ironically, I was just going to add my name to the list with the "Me too" button at the top of this thread, but that just spins the in progresss ball. C'mon Apple. Stop the marketing BS and start coding things that work.

I assume you've tried the usual workarounds, I found one that weirdly worked for me:

attempt the usual sign in, let it send a code to your device

DO NOT PUT THAT CODE IN

click "did not get a code"

click "send code by text/sms" to a number you have on hand

This worked for me after the usual:

reboot

uninstall/reinstall icloud

attempting to sign out of icloud and sign in again

removing all icloud/itunes/apple items from my computer then reinstalling

then the unusual:

attempting to administrator run the icloud program

attempting a hash reset on the console

what lead me to this fix: attempting to log in to my alt-account that I made as a kid that was still on security-questions vs 2fa

after fixing the password and upgrading it to 2fa, it successfully logged in

The big difference being, since it's not logged in anywhere, it sent me text codes.

Adding a +1 for signing out and signing back in to fix this.

However, ICloud will delete everything ICloud having to do with the application that's on your PC by signing out as others have mentioned. The material will still be on ICloud, but it won't be on your PC any longer. ICloud photos, IDrive files, etc are all unavailable - mostly "as expected". Copy/Save them separately before signing out if you need them without ICloud being hooked up or you're nervous about the implications.

The good news is that when you sign back on and agree to allow ICloud Files and ICloud Photos to set up on your Windows machine, it will resync. For pictures, that means it will sync with the pictures in the "Microsoft Picture Directory", which for most users is C:\Users\YourAccountName\Pictures, to your ICloud photos storage. For IDrive, that's what's stored on your Idevice/ICloud being shared back to Windows again for access from the PC.

I don't use Outlook so I can't tell you what happens with Contacts or Calendar. I also don't use ICloud's password sharing so I can't tell you what happens there either.

Yes same on two PC’s here. Its cause and effect started with the latest iCloud version. Very annoying.

Registry change suggested did not work.

It seems like this issue may have started after a recent update. Have you tried adjusting the iCloud settings to see if there's an option to disable the pop-up window on startup?

Under Account Details, upper right corner, the first box allows you to sign out. This did work for me.
