- Product
- iCloud for Windows
- Device & OS
- Windows 10
- Scenario
- Attempting to sign in to the iCloud application on a Windows desktop to sync contacts and calendars across Apple devices.
- Observed behavior
- The iCloud application refuses to open or complete the sign-in process, frequently displaying an incorrect-password error even after the password has been changed, preventing any local desktop syncing.

Repair or Reinstall iCloud for Windows
Use the built-in Windows repair tool to fix corrupted application files, or perform a clean reinstallation if the repair fails.
Software corruption can prevent iCloud from launching or authenticating properly. Using the Windows Control Panel to repair the installation is the safest first step.
Click the Start menu, type 'Control Panel', and open it. Navigate to 'Programs' and click on 'Programs and Features'.
Scroll through the list to find 'iCloud'. Right-click it and select 'Change' or 'Repair', then follow the on-screen prompts to fix the installation.
If repairing does not resolve the sign-in issue, right-click 'iCloud' again and select 'Uninstall'. Once removed, download the latest version from the Microsoft Store or the Apple website and install it.
Update Windows and iCloud Software
Ensure both your operating system and the iCloud application are running the latest versions to fix compatibility bugs.
Check Antivirus and Security Software
Temporarily disable third-party security software that might be blocking iCloud's connection to Apple's authentication servers.

Frequently Asked Questions
Why does iCloud for Windows keep saying my password is incorrect?
This can happen due to a glitch in how the Windows app communicates with Apple's servers, or if a third-party antivirus is blocking the authentication request. Ensure your software is up to date, and if the issue persists after a password reset, you may need to contact Apple Support.
How do I force iCloud to sync my contacts on Windows 10?
Open the iCloud for Windows app, uncheck the 'Contacts and Calendars' option, and click Apply. Then, check the box again and click Apply to force the application to re-initiate the sync process with your default email client.
Will uninstalling iCloud for Windows delete my photos or contacts?
No. Uninstalling the iCloud application from your Windows PC only removes the local syncing software. Your actual photos, contacts, and calendars remain safely stored in your Apple iCloud account and on your other Apple devices.
Can I use iCloud for Windows without Microsoft Outlook?
You can use iCloud for Windows to sync your Photos and iCloud Drive files without Outlook. However, to sync Contacts and Calendars natively on a Windows desktop, iCloud requires a compatible version of Microsoft Outlook to integrate with.
