What is Registry Checker?

A Microsoft Windows 98 utility for troubleshooting registry problems. Registry Checker can correct certain kinds of registry problems and can back up the registry regularly.

How It Works

Registry Checker comes in two forms:

  • ScanRegW:
    A protected-mode GUI-based version that you can run from within Windows to scan the registry for corruption, optimize the format of registry files, and back up the user.dat, system.dat, win.ini, and system.ini files. ScanRegW runs automatically when you start your system; you can also use it to force a scan to back up the files. The backed up files are stored as compressed .cab files in \Windows\Sysbckup.

     

  • ScanReg:
    A real-mode MS-DOS-based version that is invoked when ScanRegW finds corruption in the registry and asks you to restart the computer. ScanReg runs during restart and either restores the registry to a known good backup version or, if none exists, tries to fix the corruption.

     

Registry Checker automatically inspects the registry upon startup and attempts to either fix the problem or restore the registry from backup. It automatically backs up the Windows 98 registry each day after a successful system startup and can maintain up to five different backup versions of the registry in compressed format. Registry Checker also improves system performance by removing information from the registry that is no longer needed and by compacting free space.

TIP

To manually start Registry Checker, open the Start menu, point to Accessories and then System Tools, and choose System Information. In the Microsoft System Information window, select Registry Checker from the Tools menu.
