Your confidential information stored in the AdalCache folder on Windows 11 can be sensitive. This cache is used by Microsoft authentication libraries to store tokens and credentials. Many users want to ensure Microsoft does not access this data unnecessarily.

Stopping Microsoft from accessing AdalCache requires a few careful steps. These involve controlling permissions and clearing cached credentials. Understanding how this cache works helps you protect your privacy better.

In this guide, you will find simple, step-by-step instructions to secure or remove data from the AdalCache folder. Each step is explained in detail so even beginners can follow along confidently.

By the end, you will know how to manage your AdalCache data and reduce the chance of unauthorized access by Microsoft services.

Quick Note: What You Need to Know Before Starting

• AdalCache Location: The AdalCache folder is usually found in C:Users[YourUsername]AppDataLocalPackagesMicrosoft.AAD.BrokerPlugin. This folder stores authentication tokens for Microsoft accounts.
• Permissions: Some folders may be protected by Windows system permissions. You might need administrator access to modify or delete files.
• Impact of Clearing Cache: Deleting cached credentials means you may need to sign in again to Microsoft services or apps.
• Backup Important Data: Always consider backing up any important files before making changes.

Step 1: Locate the AdalCache Folder

First, you need to find where the AdalCache folder is located on your computer.

1. Press Windows + R on your keyboard to open the Run dialog box.
2. Type %localappdata%PackagesMicrosoft.AAD.BrokerPlugin_8wekyb3d8bbweLocalCacheAdalCache and press Enter.
3. This will open the AdalCache folder where your tokens are stored.

Knowing the location helps you manage or clear the cache directly.

Step 2: Clear Cached Credentials

Clearing the cache removes stored tokens, preventing Microsoft from accessing previous authentication data.

1. Close all Microsoft-related apps, such as Office or OneDrive.
2. Navigate to the AdalCache folder using the steps above.
3. Select all files inside the folder by pressing Ctrl + A.
4. Right-click the selected files and choose Delete or press Delete on your keyboard.
5. Confirm the deletion if prompted.

After this, you may need to sign in again to Microsoft services, but this ensures the old tokens are removed.

Step 3: Adjust Folder Permissions to Limit Access

Changing permissions can prevent unauthorized apps or users from reading the AdalCache folder.

1. Right-click the AdalCache folder and select Properties.
2. Go to the Security tab.
3. Click Edit to change permissions.
4. Select any user or group you want to restrict access from.
5. Under Permissions, uncheck Read and Read & execute.
6. Click Apply and then OK.

This step is important because it limits who can view or modify your cached credentials.

Step 4: Disable Microsoft Account Integration (Optional)

If you want to reduce Microsoft’s ability to cache credentials, consider using a local account instead of a Microsoft account on Windows 11.

1. Open Settings by pressing Windows + I.
2. Go to Accounts.
3. Click on Your info.
4. Choose Sign in with a local account instead.
5. Follow the prompts to create and switch to a local account.

This will reduce the use of cached Microsoft tokens on your device.

Alternative Method: Use Windows Credential Manager to Remove Stored Credentials

Sometimes credentials are also stored in the Credential Manager. Removing them can further protect your information.

1. Open the Control Panel.
2. Search for and click Credential Manager.
3. Under Windows Credentials and Web Credentials, look for any Microsoft-related entries.
4. Click on each entry and select Remove.

This helps clear credentials stored outside the AdalCache folder.
