  9. For each program you want to block, create a new string value in the DisallowRun subkey . Use consecutive numbers to name the string values (starting with 1), and use the executable file name of the program as the data for the string value.For example, if you want to restrict users from running Internet Explorer:
    1. Navigate to the following key in Registry Editor:
      HKEY_CURRENT_USER\Software\\Microsoft\Windows\\CurrentVersion\\Policies\\Explorer\\DisallowRun. Then right click in the right side panel and create a new string value. Type 1, and then press ENTER.
    2. Double-click “1″ that you created in the previous step.
    3. Type iexplore.exe in the Value data box, and then click OK.
  10. Quit Registry Editor, and restart your explorer or computer to load new settings.

After restarting your computer try to run internet explorer. If you followed this correctly then you will see an error message similar to below image.

To regain access simply delete the key which you created during the process and restart your computer. Have fun 😉

Kolibri OS – smallest OS with GUI

Yes this is true. KolibriOS is as small as 1.4 mb and can fit in your Grandfather’s floppy disk. Kolibri OS is a free operating system based on Menuet OS and is available in two different versions, 1.44 MB and a bigger one – with more features – of about 3 MB. It is completely written in assembly language and you can boot into it using floppy disk, hard disk, CD or DVD.

It does not have any good graphics or does not even support the variety of softwares which are available for Windows, Linux or Mac. But believe it or not, it has everything that is needed for performing basic tasks e.g Text Editor, Email Client, Task Manager, Programming Tools and a virtual desktop too.It also consists of a simple http client to surf the internet.

See this video to know more about this OS.

This OS supports NTFS file system and requires only 8 mb of RAM to run. Don’t underestimate this OS because of its size. It has got almost 8-10 games like tetris, rocket fight(don’t remember the exact name)  etc. This OS can be actually very useful when you have to access some data from age old machines.

You can boot into this OS using Floppy, CD/DVD or your Hard Disk. Or you can also try using any virtual machines like VMware or Sun VirtualBox

This is the smallest OS with GUI I have ever seen. If you know any other OS which is as small as this one and also has GUI then please let me know.
