How to Take Ownership of a Item in Vista and Windows 7
InformationThis 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.
NoteYou 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.
WarningThis 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.
EXAMPLE: You need permission to perform this action
NOTE: You will see this Access Denied with the Try Again type message when your user account or group does not have Ownership of the file. Clicking on the Try Again does nothing.
OPTION ONE 
1. For how, see: How to Add Take Ownership to the Context Menu in Vista
OPTION TWO EX: To Take Ownership of this System file:
C:\Windows\System32\en-US\winload.exe.mui
EX: User name to Take Ownership with: Brink
1. Open an elevated command prompt.
2. In the elevated command prompt, type the command below and press Enter to take ownership of the file.
NOTE: Substitute full path of file with the full path of the file that you want to take ownership of within quotes.
takeown /f "full path of file"
For example:
takeown /f "C:\Windows\System32\en-US\winload.exe.mui"
3. A message will be displayed that this completed successfully. This will give you ownership of the file.
4. In the same elevated command prompt, type the command below and press Enter to grant a user full control of the file.
NOTE: Substitute full path of file with the full path of the file from step 2 within quotes , and (user name) with your user name.
icacls "full path of file" /grant (user name):F
For example:
Code:
icacls "[B][COLOR=red]C:\Windows\System32\en-US\winload.exe.mui[/COLOR][/B]" /grant [B][COLOR=red]Brink[/COLOR][/B]:F
5. A message will be displayed that this completed successfully.
NOTE: You should be able to delete or modify the file now. If you still can't, you may need to reboot into Safe Mode and try this again. It may vary according to the file. Some are more stubborn.
OPTION THREE 1. Go to the file, folder, drive, or registry key you want to delete or modify.

C:\Windows\System32\en-US\winload.exe.mui
2. For a File, Folder, or Drive
