keeps unwanted programs

There are some Windows programs that you can't uninstall, no matter how hard you try. But you can keep yourself from launching them accidentally. There are a number of ways to do this, but one of the easiest is to run Application Locker, a free utility that lets you "lock" users out of certain apps.When you launch Application Locker the first time you'll see a list of commonly blocked programs including some that you might not even have installed on your system. You can configure the list by removing these items or by adding any executable file on your system. You don't need to add the complete file path, just the name of the executable. For instance, you can lock Internet Explorer by adding "iexplore.exe" to the block list.You can also use Application Locker to prevent your kids from opening the web browser, or as a reminder to yourself to keep your IM client closed during working hours. Of course, anyone can reenable blocked applications simply by running the program and unblocking them. So I wouldn't advise using Application Locker as a security tool, but rather as a utility to make it a bit tougher to accidentally fire up the wrong program.[via gHacks]
