It says pick a restore point - that will be before a given restore point.
If you highlight that restore point does it take you back to the point at which it was when the last or selected Restore point was?
By that I mean. Say you have the following sequence.
1. Manually selected restore point. 15/1/2015
2. Restore point after Loading Photoshop 12/1/2015
3. Manually created Restore point before Loading Photoshop
4. Restore point created after Loading MS Office.
If I highlight Restore Point 3.
Will it be the system with MS Office but without Photoshop.?
