Improper Shutdown May Affect System Restore (Q283096)

When you use System Restore to perform a restoration to your system, System Restore may not restore all files as expected. You may also receive the following error message when you restart the computer after the restore process:

System Restore
Restoration Incomplete
Your computer cannot be restored to:
Date
Restore Point Name
This restoration is incomplete. It was interrupted by an improper shutdown. You should undo this restore or choose another restore point.
To choose another restore point, restart System Restore.

This behavior can occur when the computer is not shut down properly. For example, this issue occurs when there is an accidental or intentional improper shutdown during the restoration process.
