The user encounters the issue when he fails to change the default save location for the new Microsoft Store apps. For some of the users, the New Apps will save to dropbox does not have the target drive, or the said option is greyed out. In some cases, where users were able to set the path to the target drive, the Store kept on using the path to the C drive (not on the target drive). Before moving on with the solutions to change default storage, check if restarting the system solves the issue. Moreover, check if your disk is fast enough to hold the Store Apps. Last but not least, make sure to update the Windows of your system to the latest build.
Solution 1: Use the PowerShell to Remove the Target Drive
You may encounter the error under discussion if the target drive was previously used for Microsoft Store apps installation. In this scenario, removing the target drive from the Microsoft Store “memory” may solve the problem.
Solution 2: Change the Group Policy
You may encounter the error at hand if the group policy of your system bars it from installing Windows apps to a non-system volume. In this case, disabling the said policy may solve the problem.
Solution 3: Use the Registry Editor to Remove the Old Windows Apps Reference to the Target Device
You may fail to change the path of Microsoft Store apps if the registry of your system has an old reference to the target drive. In this case, removing the registry entry referring to the target device may solve the problem. Warning: Proceed with caution as editing the system registry requires a certain level of expertise & if not done properly, you may cause everlasting damage to your system/data.
Solution 4: Disable Compression or Encryption of the Target Drive
You may fail to change the default location of the new Microsoft Store apps if the target drive is encrypted or compressed. In this context, disabling compression or encryption on the target drive may solve the problem.
Solution 5: Change the Target Drive Permissions
You may fail to set the default path for Windows Store apps if the permissions of the target drive do not allow you to make the relevant changes. In this scenario, editing the drive permissions may solve the problem. Warning: Proceed with caution because if the security permissions are not configured properly, you may expose your system and data to threats. Moreover, to correct the security permissions (if done wrong) you may have to format the drive.
Solution 6: Reset the Microsoft Store
You may encounter the error under discussion if the installation of Microsoft Store is corrupt or the Store is misconfigured. In this context, resetting the Microsoft Store may solve the problem.
Solution 7: Remove the Windows Folders from the Target Drive
You may fail to set the default Store apps path to another drive if that drive has a similar directory structure as required by the Windows (e.g. WindowsApps and WPSystem folders as a result of a previous installation). In this case, deleting the traces of previous Windows apps installation may solve the problem.
Solution 8: Set the Default Windows Applications Path and Perform SFC/DISM Scans
You may encounter the error at hand if the files essential for the operation of Microsoft Store is corrupt. In this case, performing SFC and DISM scans may solve the problem. If the issue is still there, then you should format the target drive (after backing up the essential data) and check if the issue is resolved. If not, then either perform a repair install of Windows or a clean install of Windows.
