Most of the Windows users are in the habit of shutting down their computers if they no longer need it for a longer period of time. I myself am in the habit of shutting down my Windows computers after a day’s hard work. It helps save the electricity and gives some time for the PC hardware to cool off. But there are many others who need their computers up and running all the time without any interruptions. And if some unforeseen circumstances cause the PC to reboot or shutdown, then they must intercept it at once.
A little utility called Shutdownblocker could prove to of immense use for the people who want full control over the shutdown or restarts of their Windows PC. This tool blocks all the calls and requests to shutdown or restart your PC made by other users or applications. It can prevent a reboot of Windows initiated by the automatic updates after some updates are installed.
The Shutdownblocker tool does not require any installation but it depends on .NET 4.0 framework which comes pre-installed in Windows 10. The simple utility shows up in a small window with two big buttons – Block and Allow. By default, the shutdown is blocked as soon as you launch this program. But you can click on the Allow button anytime to allow the shutdown of Windows. You can also switch back and forth between blocked and allowed states from the notification area icon of the Shutdownblocker.
If you do not launch Shutdownblocker with administrative privileges and then certain features are not available. For example, you must be running it with administrative access before you can check the option to intercept shutdown.exe and MusNotification.exe.
In the options for Shutdownblocker, you can choose to run it at Windows startup automatically, launch it without showing any system tray icons, add a shortcut to Windows start menu, and allow some critical messages to be displayed on top of all the other windows.
When I tried to run a command to shutdown Windows by typing shutdown.exe /s /t 36000 in the command prompt, it did intercept the shutdown.exe command but it also showed an exception error. Perhaps it is some program glitch or some detailed information about how the shutdown.exe was blocked.
Conclusion: Shutdownblocker could help prevent accidental or unwanted shutdowns or reboots in Windows. It intercepts all the calls to shutdown and can even suppress critical error messages.
