Hi @Tina Mills ,
restore points are stored in the System Volume Information
folder on each drive. For instance C:\System Volume Information
.
If you don't see the folder in Windows Explorer you should change the view options:
Folder Option
-> View
-> Uncheck Hide protected operating system files
and check Show hidden files, folders and drives
