If life were like your computer, you could install Roxio's GoBack 3 Deluxe and undo everything you wish you never did. The program inserts itself between Windows and your hard disk, recording every file that has been changed, added or deleted -- whether by you, by Windows or by a rampaging virus.
GoBack creates a hidden storage area on your disk -- by default, 10 percent of your total disk space -- and uses it to store only the changes between different versions of a file rather than multiple copies of the file itself. It stores a complete file only when a file gets deleted.
So if you decide that the friendly first version of a letter is better than the angry current version, just right-click on the file in Windows Explorer, select Show Revisions from the pop-up menu, pick an earlier version from a list, and GoBack either replaces the current version with the older one or lets you save the old one under a different name.
Whenever you restart your system, a GoBack menu appears for a few seconds before Windows starts up, so if a virus makes Windows unbootable, you can choose Revert Drive from the GoBack menu and bring back your system's pre-viral state. Computers in public and semi-public places such as schools, hotels and libraries can use GoBack to revert automatically to a clean condition at regular intervals or every time a user logs off.
Roxio seems to have thought of every possible recovery scenario: so when you revert your system to its condition two hours previous, the program pops up a list of files that changed during the period you just wiped out and it lets you recover any work you did during that time. A dazzlingly ingenious option displays an Explorer window with a virtual disk that represents a prior state of your system, so you can drag files from the older disk into the current version.
Compared with less ambitious system-recovery tools such as the System Restore feature in Windows ME, GoBack records changes to every file on your disk, resulting in cluttered lists of recoverable files in its retrieval menus. You can tell the program not to list temporary and other discardable files in its lists, even though the program continues to record changes to those files in the background. GoBack won't work with third-party multi-boot managers such as PowerQuest's BootMagic, but works smoothly with the multi-boot option built into Windows NT and 2000.
Anyone who understands Windows' inherent fragility may hesitate to install a product that works at such a low level, but GoBack seems rock-solid and produced no detectable slowdown on our test system. If you like dangerous computing, GoBack may be the best protection you can find.
