If you are a Windows 7 user, then you are most likely to be aware of the fact that you need to TAKE OWNERSHIP of files and folders before you can make any changes to them. This feature was introduced first in Windows Vista and later in Windows 7 in order to prevent any unauthorized changes from being made to the system files.

• Right-click the file or folder on which you want to take the ownership and then click on Properties.

• Now go to the Security tab, click on Advanced button and then click the Owner tab.
• Now, click on Edit and do the following:

• Under the “Change owner to:” section, select the user or group to which you would like to grant the permissions and then click on the OK button.

• If the user or the group to which you would like to grant permissions is not listed under the Change owner to: section, just click on Other users and groups and, under Enter the object name to select (examples), type the name of the user or group, and then click OK.

• Now you should get the confirmation dialog box stating that the ownership is granted.
