2. Switch to the Security tab and click Advanced.
3. At the top, you'll see the Owner. Click Change.
4. Enter your user account name (or "Administrators" group), then click Check Names.
5. Click OK.
6. Back in the Advanced Security Settings window, check Replace owner on subcontainers and objects (if applicable).
7. Click Apply and OK.
