Stop Windows 11 Apps Installing on Other Drives

By default, Windows 11 installs new apps from the Microsoft Store to the same drive as your operating system (usually C:), and many desktop apps also default to that location. You can prevent this by changing the default storage location in Settings, or by choosing a different drive during manual installation. This article explains the built-in methods, what they do and don’t cover, and how to handle apps that ignore your preferences.

Why Apps Install on Non-System Drives

Windows 11 is designed to put system files and most applications on the boot drive (C:). This keeps the operating system and its core programs together, which simplifies updates, permissions, and recovery. However, this also means every new app you install consumes space on that drive. If your C: drive is a small SSD, it can fill up quickly with large games, design software, or even modest utilities.

Microsoft Store apps are normally installed to C:\Program Files\WindowsApps, a hidden folder that is protected by the operating system. Traditional desktop apps (Win32) typically install to C:\Program Files or C:\Program Files (x86). Both locations are on the system drive by default. The setting that changes this behavior is called “Where new content is saved” in the Storage settings, and it applies to new apps, documents, music, photos, and videos.

How to Change the Default App Installation Drive

Windows 11 includes a simple toggle that tells the system where to put new apps. Here’s how to use it:

Open Settings (press Windows + I).
Go to System > Storage.
Click Advanced storage settings and then Where new content is saved.
Under New apps will save to, select a different drive from the dropdown menu.

This setting applies to apps installed from the Microsoft Store and to some desktop apps that respect the system default. It does not change where existing apps are stored, and it does not force every third-party installer to comply. Many traditional installers still ask you to choose a location during setup, and that choice overrides the system default.

What This Setting Actually Covers

The “Where new content is saved” setting is a preference, not a hard rule. Here’s what it affects:

New Microsoft Store apps – these will install to the drive you select.
Some desktop apps – if the installer respects the system default, it will use your chosen drive.
New documents, music, photos, and videos – the same screen lets you set default save locations for these file types.

It does not affect:

System components and updates – these always go to the system drive.
Apps that force a specific location – some installers hard-code the path or don’t offer a choice at all.
Apps already installed – you must move them manually or reinstall them.

How to Move Existing Apps to Another Drive

If you already have apps on C: and want to move them, Windows 11 offers a built-in move feature for Store apps and some desktop apps:

Open Settings > Apps > Installed apps.
Find the app you want to move, click the three-dot menu, and select Move.
Choose the destination drive from the dropdown and click Move.

This works for many apps, but not all. If the Move option is grayed out, the app doesn’t support being moved. In that case, you can uninstall and reinstall it to the desired drive, or use a third-party tool that moves apps by creating symbolic links (though that’s more advanced and can break updates).

Manual Installation: Choosing the Drive During Setup

For traditional desktop apps, the most reliable method is to choose the installation directory during the setup wizard. Most installers show a screen that says “Choose installation location” or “Destination folder.” Click Browse and select a folder on another drive, such as D:\Program Files\AppName. This is straightforward and works for nearly every Win32 app.

Some installers don’t show a location choice by default. Look for an “Advanced” or “Custom” installation option, which often reveals the path selection. If the installer forces a location and doesn’t allow changes, you may need to use the registry or a symbolic link, but that’s not recommended for casual users because it can cause problems with updates and uninstallation.

Common Problems and Misconceptions

One common misconception is that changing the default drive will move all future apps automatically. In practice, many third-party installers ignore the system setting and default to C: anyway. Another issue is that some apps require being on the same drive as the operating system to work correctly – for example, drivers or apps that integrate deeply with Windows Explorer. Moving such apps can cause them to malfunction.

Another problem: if you select a drive that is not always connected (like an external USB drive), Windows may fail to install or launch apps when that drive is absent. Always choose an internal drive that is always available. Also, note that the “Where new content is saved” setting does not affect Windows updates, which will still use the system drive.

Alternatives to Changing the Default Drive

If you want to keep your system drive clean but don’t want to manage per-app locations, consider these alternatives:

Use a larger system drive – replacing the C: drive with a bigger SSD is a permanent solution.
Enable Storage Sense – this automatically frees up space by removing temporary files and cleaning up recycle bin contents.
Move user folders – you can move Documents, Downloads, and other folders to another drive to free up space.
Use a symbolic link (advanced) – create a junction from C:\Program Files\App to D:\Apps\App. This is risky and not recommended unless you know what you’re doing.

For most users, the built-in setting plus manual selection during installation is enough. If you frequently install large games, consider using a dedicated games library on a secondary drive, as game launchers like Steam and Epic allow you to set installation folders.

Frequently Asked Questions

Why don’t all apps respect the default drive setting?

Because the setting is a suggestion for developers. Many installers are coded to use the system drive unless the user explicitly chooses otherwise. The Windows 11 setting only affects apps that query the system for the default location, which is more common with Store apps than with traditional desktop software.

Can I move apps to an external drive?

It’s possible, but not recommended for most apps. External drives can be disconnected, which will make apps unavailable. If you do use an external drive, make sure it’s always connected when you need the app. Some apps may also run slower on a USB drive.

Will moving an app break its updates?

It depends on the app. Store apps moved via Settings will update normally. Desktop apps that are manually reinstalled to another drive usually update fine. However, apps that rely on hard-coded paths (like some drivers) may fail to update or uninstall correctly.

How do I change the default drive for new apps if the dropdown is grayed out?

This can happen if you have only one drive or if the drive is not formatted with NTFS. Make sure you have at least two internal drives, and that the secondary drive is formatted with NTFS. If it’s still grayed out, restart your PC and try again.

Is it safe to move Microsoft Store apps to another drive?

Yes, for most apps. The built-in Move feature is designed to handle this safely. However, some system components and apps that integrate deeply with Windows (like Cortana or certain drivers) cannot be moved, and the option will be disabled.

What if I want to move an app that doesn’t have a Move option?

Your best bet is to uninstall the app and reinstall it to the desired drive. If that’s not possible, you can try using a symbolic link, but this is advanced and may cause issues. Always back up your data before attempting registry or file system changes.
