Hit Next and click Show more restore points.
Select a restore point where your programs were still installed, then select Scan for affected programs to see what programs will be affected if a system restore is performed.
If you agree with the possible changes on your system, click Close, then hit Next.
Save and close any programs that are opened, then hit Finish.
Click Yes to start the system restore process.
Hope above information can help you.
