How to delete Windows OneCare Backup folder

I used Windows OneCare (WOC) for several weeks and in that time period I backup windows in my external hard drive. Windows OneCare (WOC) was annoying for me because it ask your permission for everything. So I decided to remove, but it did not let me remove that backup file. So after little research work on WOC, finally I find the way.

How to Delete Windows OneCare Backup Folder:
These are the steps

Open the folder WINDOWS ONECARE IS SAVED
Single click on WOC then see left side "Share This Folder" Click on it
Then click on sharing tab
Section of Network Sharing and security
Share this folder on the network "check that box"
Check box "allow network user to change my file"
Then click apply
Then ok
Then select WOC folder and hit DEL
Enter "yes"
Now it’s gone.
