\"lockup-icon\"<\/a> [Windows Only<\/em>] Do you manage or share user accounts on a PC? Are there certain programs that you don\u2019t want someone to use? A tiny stand-alone<\/a> freeware application named \u2018Lockup<\/em>\u2019 will let you lock programs so they won\u2019t run at all.<\/p>\n

Lockup is very easy to use, but you should be very careful with it. If you make one wrong move, you can accidentally lock an entire user account so that it\u2019s difficult to return to a usable state.<\/p>\n

How to use Lockup:<\/strong><\/p>\n

Here\u2019s a screenshot of one of the two modes of operation, \u201cOnly the list<\/em>\u201d mode.<\/p>\n

\"lockup-block-internet-explorer\"<\/a><\/p>\n

In the screenshot above, you can see that I\u2019ve added Internet Explorer to the list of executable files that will not run. To add more executables to the list, click the \u201cBrowse\u201d button to select an EXE file, then click the little green check-mark icon at the bottom of the Lockup window. After you reboot or log off the PC and log back in, you\u2019ll find that the EXEs you\u2019ve listed will bring up a message telling you that the program is \u201crestricted\u201d.<\/p>\n

Below, you can see a screenshot of Lockup in the \u201cAll except the list<\/em>\u201d mode.<\/p>\n

\"lockup-block-everything\"<\/a><\/p>\n

This is a fairly risky mode since all executable files will be blocked from running, except those you add to the list. Make sure you don\u2019t remove Lockup from the list or you may have a little trouble getting back access to it. I tried this mode briefly and it works great. All of my autorun (startup<\/em>) applications failed to load when I logged in, even my antivirus application was blocked. This mode would be perfect for a PC that was used in a public place such as a library, school or cafe.<\/p>\n

How does it work?<\/strong><\/p>\n

Occasionally, I run into a little program like this and I have to figure out what it\u2019s doing. I learn lots of neat tricks this way. I suspected that Lockup<\/em> was only making some changes to the Windows Registry and I was correct. I used an installation monitor<\/a> to find out what changes it made in the second mode I showed you above.<\/p>\n

\"lockup-block-registry-settings\"<\/a><\/p>\n

As you can see in the image above, Lockup<\/em> made changes to the Current_User policy to achieve the blocking it does. Anyone with the knowledge of these registry keys can do the same thing using the Windows Registry Editor (regedit.exe<\/em>). Here\u2019s a link to more information on the DisallowRun and RestrictRun registry keys<\/a>.<\/p>\n

Final Tips:<\/strong><\/p>\n

If you do get blocked from using programs or a specific program, you can still launch them using the Windows Run menu (Press Windows key + R<\/em>) or from the command console (Press Windows key + R \/ type \u2018CMD\u2019 without quotes \/ press Enter<\/em>). For example, if I wanted to run Notepad, I could type \u2018notepad\u2019 into the Run menu.<\/p>\n

You can run Lockup from a USB flash drive if you want to make sure that nobody using the PC has access to the Lockup program. This could also be used for a practical joke if you are feeling mean (not recommended<\/em>).<\/p>\n

Also \u2026 here\u2019s how to:<\/p>\n

* Password Protect Programs and Files<\/a>
\n* Lock and Hide Files and Folders<\/a>
\n* Hide Your Secret Files in Zip Folders<\/a><\/p>\n

Techie Buzz Verdict:<\/strong><\/p>\n

If you need to keep people from running specific applications on your PC, this little freeware app could be one of your favorite tools. It\u2019s small, easy to use and it\u2019s free.\u00a0The only thing missing from this application is a password protection feature.<\/p>\n
