Abstract
A system and method for recovering from corruption of an executable application and/or operating system stored on a client computer without downloading another copy of the application and/or operating system. This recovery is accomplished by storing, preferably at the initial program loading, two copies of the application (and the operating system, if desired) in different segments of a partitioned storage, one copy as a working copy and a second copy as an archive or backup copy. When the working copy of the application or operating system becomes corrupted and crashes, the backup copy is thereafter used as the new working copy and, if desired, a new backup copy is stored to be used when the working copy crashes. This allows the system to continue functioning after a crash without the necessity to find a new copy of the application and operating system from outside the computer.
