Shutdown Lock allows enabling hibernate and standby features in applications like FlashGet. It can enhance the safety of Windows XP fast user switching to prevent any data loss caused by unexpected system shutdowns or restarts.

Shutdown Lock is a small utility that does the job effectively, taking up just about 64 KB. It empowers third-party software to force a PC into suspension or hibernation, rather than shutting it down.
This software has four primary objectives it was designed to achieve: enabling hibernate and stand by features in applications like Nero Burning ROM, FlashGet, or AudioGrabber, using Windows XP fast user switching more safely, preventing unexpected system shutdowns or restarts that could cause sensitive data loss, and operating stably and unobtrusively.
When you load Shutdown Lock upon startup, it sits quietly in the system tray. You can enable or disable it with just one click. If enabled, the program will either hibernate or suspend your PC when a program prompts a system shutdown. This is a very valuable feature because it prevents accidental data loss.
This software is especially useful for people who share their PCs with kids or others prone to shutting down or reloading accidentally. Shutdown Lock can also be used as a quick and easy way to suspend or hibernate a PC, without accessing Windows' Start menu.
Finally, Shutdown Lock can also be used as a tiny shutdown command line utility, enabling you to create a shutdown shortcut to shut down your computer automatically, identify the application requesting a system turn off/restart, and more. Overall, Shutdown Lock is an effective, easy-to-use software that can preserve your work and data while making your computer experience more convenient.
