Operating Systems: System Restore

You install an application on a computer running Windows XP. The application automatically creates an installation restore point before making any changes to the computer, installs itself, and restarts the computer automatically.
You are able to log on, but are not able to run several applications. The computer reports various errors when you attempt to launch these applications. You can launch most system utilities.
What should you try to correct this problem?
1. Run Start | Control Panel and launch Add or Remove Programs. Select and remove the application.
2. Shut down the computer, restart, interrupt the startup, and choose to start using the last known good configuration.
3. >>Run Start | All Programs | Accessories | System Tools | System Restore and revert to the most recent system checkpoint.
4. Run Start | All Programs | Accessories | System Tools | System Restore and revert to the restore point created by the application. -->Correct

Explanation : You should run Start | All Programs | Accessories | System Tools | System Restore and revert to the restore point created by the application. Because the problems occurred immediately after installing the application, they are most likely related to the application. The restore point was created before the application was installed, so reverting to the restore point would take the system back to a point just before installation. If the problem is related to the application, this should correct the problem.

You should not shut down the computer, restart, interrupt the startup, and choose to start using the last known good configuration. The last know good configuration is the configuration when the computer last started up successfully. Because the computer has successfully completed startup since you installed the application, booting to the last known configuration will use the current configuration, which includes the application.

You should not run revert to the most recent system checkpoint. A system checkpoint is created when Windows XP detects a request to make a configuration change. Depending on when the checkpoint was created, you might lose changes to the computer that you want to keep.

You should not remove the application. This process will uninstall the application, but it does not necessarily reverse all of the changes made during application installation.
