Delete Gpo Cache

6 min read Oct 11, 2024

What is a GPO Cache?

A Group Policy Object (GPO) cache is a local copy of Group Policy settings stored on a computer. These settings are applied to the computer and its users, defining things like security settings, software installations, and desktop configurations. When a user logs in or the computer boots, it checks for changes in the GPO and applies the relevant settings.

However, this caching mechanism can sometimes cause issues. If a GPO is modified or deleted, the local cache might not reflect the changes immediately. This could lead to outdated settings being applied, causing inconsistencies and even security vulnerabilities.

Why Delete the GPO Cache?

Here are some common reasons why you might need to delete the GPO cache:

Applying new GPO settings: When you make changes to a GPO, the local cache needs to be refreshed to reflect the updates.
Troubleshooting GPO issues: A corrupted or outdated GPO cache can cause various problems. Deleting it can help resolve these issues.
Implementing security changes: If you've made significant security updates to your GPO, deleting the cache ensures that the new settings are applied correctly.
Migrating a computer: When moving a computer from one domain to another, you might need to delete the GPO cache to ensure that the correct policies are applied.

How to Delete the GPO Cache

There are several ways to delete the GPO cache:

Method 1: Using the `gpupdate` command

This command updates the GPO settings on the local computer. To force a refresh and clear the cache, use the following command:

gpupdate /force

Method 2: Using the Group Policy Management Console (GPMC)

Open the Group Policy Management Console (GPMC).
Navigate to the computer or user for which you want to clear the cache.
Right-click on the object and select "Refresh".

Method 3: Manually deleting the cache files

Open File Explorer and navigate to the following folder:
```
C:\Windows\System32\GroupPolicyUsers
```
Delete all the files and subfolders within this directory.
Repeat the process for the following folder:
```
C:\Windows\System32\GroupPolicy
```

Note: Deleting files manually is not recommended unless you are sure you are not removing any critical system files.

Important Considerations

Admin Privileges: You need administrative privileges to delete the GPO cache.
Impact on users: Clearing the cache may briefly affect logged-in users. They may need to log out and log back in for the new policies to take effect.
Backup: Before deleting the cache, consider creating a backup of the files in case you need to restore them later.

Troubleshooting Tips

Verify GPO links: Ensure that the GPOs you are trying to apply are correctly linked to the desired organizational unit (OU) or computer.
Check for conflicting policies: If multiple GPOs apply to a computer, make sure that the policies do not conflict with each other.
Restart the computer: After deleting the cache, restarting the computer can help apply the new settings.

Conclusion

Deleting the GPO cache is a powerful tool for troubleshooting and applying new settings. However, it's crucial to understand the implications and follow the recommended methods to avoid disrupting user sessions and potentially corrupting the system. By understanding how the GPO cache works and how to manage it effectively, you can ensure that Group Policy settings are correctly applied and your network remains secure and efficient.
