Vista - Take Ownership of file

Information

This will show you how to take Ownership of a file, folder, registry key, or drive where you have been denied access to allow you to give full control of it so that you will be able to delete or modify this item. When you do this, you replace the security permissions to have access.

NOTE

You will quickly notice that you cannot delete or modify system files, even as administrator in Vista. This is because Vista system files are owned by the TrustedInstaller service by default, and Windows File Protection will keep them from being overwritten. You will encounter a "Access Denied" error.

Tip

If you are trying to delete a folder, then sometimes you will need to delete the contents within the subfolders first before you will be able to delete the main folder itself. The hidden My ..... folders are actually a Junction Point to the real username user folders. They cannot be modified since they are not a real location. EX: My Documents for C:\Users\(your username)\Documents For more on junction points, see: jimmah.com: Why do I get an Access Denied error when trying to open a folder? Sometimes you will need to move the file to the desktop or a user folder first before Vista will allow changes to be made to it. You can then move the file back afterwards. You will sometimes need to take ownership of Files and folders created in another operating system when migrated into Vista.

WARNING

This can only be done while logged on to a administrator account. Deleting or modifying system files without knowing what you are doing may lead to eratic behavior from Vista. Even complete system failure with full data loss.
