Você teria que fazer um ponto de restauração no momento antes de restaurar e restaurar "de volta para o futuro"
Edit: De maneira mais rápida, isso sempre é feito; -)
System Restore lets you easily restore your computer to a previous state. What happens if you complete the restore process but your computer is still not running properly? It is possible that you unintentionally restored Windows 7 using the wrong restore point. In such cases, you can undo a system restore operation and select a different restore point.
To undo a system restore operation in Windows 7:
- Click Start and type System Restore in the search box. From the list of results, click System Restore.
- Click Undo my last restoration and click Next.
- Review your choices and click Finish.
- Your computer will restart once the process is complete. Log on to the computer.
