thinking of upgrading to 11

Sign in to Microsoft Solitaire Collection with the same Microsoft/Xbox account before and after upgrading; the app saves progress, levels, awards, and scores to that account for synchronization across supported devices.^1^

Before upgrading

1. Open Microsoft Solitaire Collection on Windows 10 while connected to the internet.
2. Check that the game shows your Microsoft/Xbox profile rather than Guest.
3. Confirm that your current level and statistics appear under that profile.
4. Close and reopen the game once while online, allowing any pending synchronization to finish.
5. Record screenshots of important levels, statistics, and awards as a precaution.

After upgrading, install or open Microsoft Solitaire Collection and sign in with the identical account. Cloud-synchronized progress should then download. Game Saves generally maintain a local copy and synchronize it to the cloud; when cloud data is newer, the game downloads it to the device.^2^^3^

Where the local data may be stored

Games using Xbox Game Saves can keep local data under one of these structures:

%LocalAppData%\Packages\<PACKAGE_NAME>\SystemAppData\wgs\
%LocalAppData%\Packages\<PACKAGE_NAME>\SystemAppData\xgs\

The exact folder and saved-data contents depend on the game.^4^ The available documentation does not identify which exact package subfolder Microsoft Solitaire Collection currently uses, so do not move, edit, or replace files there; direct manipulation can create synchronization conflicts.

If Solitaire currently shows Guest, the available evidence does not establish that those local-only levels can be transferred reliably. In that case, avoid resetting or uninstalling the app before the upgrade and contact Microsoft Casual Games Support from within Solitaire for account-linking or recovery options.

Windows 11 upgrade behavior

For a normal in-place upgrade from Windows 10 to Windows 11, the default behavior is to move files and data into the new installation. Microsoft nevertheless recommends backing up important data before installing a new Windows version.^5^

The safest combination is therefore:

• Verify Solitaire is signed in and synchronized.
• Keep a separate backup of personal files.
• Perform an upgrade that keeps files and apps, rather than a clean installation.
• Open Solitaire online afterward and use the same account.
• If a local-versus-cloud conflict prompt appears, compare the displayed dates or progress carefully and select the copy containing the latest level.^3^
