Certain programs are more important than others, particularly if you use them to conduct certain workflows. Think writing documents in Word, editing photos, working on CAD projects, and so on. Not wanting anyone to tamper with them is understandable, notably on a shared computer.

What you can do in such a scenario is to somehow prevent unauthorized access. This can be done with a utility like Program Blocker, which is a portable, easy-to-use tool that locks a program’s executable file, so that only you can access it.

At its core, the utility is essentially a software blocker that only lets you run a certain program if you input the password. This isn’t anything particularly new, but it can prove useful if there are certain programs on your computer that you don’t want anyone else to tamper with.

It should be noted that the app comes in portable form, requiring no installation to get everything up and running. As such, all that remains to do is decide on a password, then start adding the apps you wish to encrypt.

It’s not unusual to forget a password or two, and it can be especially frustrating when there’s no way to retrieve it. In this case, the implementation of a security question is a clever one, as it gives you a good opportunity to recover your password if you do lose it in the future.

I should also mention that you can lock other executable files, such as games, just fine. Perhaps this can come in handy for parents looking to restrict gaming access from their kids.

Program Blocker’s approach is very simple, but it can be quite effective. While I would have liked to see some additional possibilities for configuration, such as locking apps based on a schedule, this is nevertheless a solution that can prove useful in many cases.
