Undo Your System Restore
Sometimes reverting to a chosen restore point doesn't solve the problem; it may even cause more problems than you had before. If you don't like the state of the Windows system after running the System Restore process, you aren't stuck with it. If an issue arises during restoration and the process fails, System Restore will automatically reverse any changes and return the computer to the state it started in.
You can reverse a successful restoration by taking the following steps:
1. Click Start, All Programs, Accessories, System Tools, System Restore (or type System Restore in the Windows 7 search field).
2. After having completed a System Restore, the program disoplays a different window of text. It offers you the option of undoing the recently completed System Restore, or of choosing a different restore point.
3. To where you started, select Undo System Restore, and click Next.
4. System Restore will present the same confirmation screen and warnings as before. Follow the same steps as you did to initiate a System Restore, and this time your system will return to its original dysfunctional state.
Not a Cure-All
System Restore is an awesome tool. Usually, you don't need to know or care what the underlying problem is. As long as you know that a problem exists now that didn't exist yesterday, you can use System Restore to revert to the Windows system state from yesterday, and voilà! Instead of wasting time with potentially painstaking troubleshooting, you just get the problem fixed.
The time-traveling magic of System Restore won't work for all situations, however. Remember, System Restore deals only with applications and the Windows system state--not with personal files. So, if you delete the only photo you have of your child learning to ride a bike, or if your only copy of your doctoral dissertation gets corrupted, or if you accidentally sent an e-mail slamming your boss to your boss, you're still out of luck.
For photos and documents, the answer lies in performing regular periodic backups. It's also just as important that you store the backup securely, preferably in a location where it won't be destroyed along with the original data if a fire or natural disaster occurs. Or you can use a disaster-proof drive, such as the ones offered by ioSafe.
As for the e-mail snafu with your boss, technology won't save you. Apologize profusely and, in the future, exercise caution before hitting Send.
