The shell is the operating system’s command interpreter and the set of commands you use to communicate with the system.

Running Linux From a USB Drive as a Virtual Machine or Bootable Disk.

There are basically two options when it comes to running Linux from a USB drive: from within Windows using virtualization software such as VirtualBox, or creating a boot disk.

if you want to run a Live Linux environment but need to retain access to Windows. Perhaps you just want to do something real quick without rebooting, or want to be able to hide the virtualized Linux instance. Our preferred weapon of choice here is a little tool called LinuxLive USB Creator.

Beware, Can Change The Processor Name Parmanently

Beware, When you purchase of Computer/Laptop

A while ago on Tweak And Trick, I published an article on changing your processor name. But recently, Somebody pointed out that the trick only changed the name temporarily.

After a user restarts his computer, the name reverted back to original which is obvious as each time Windows boots, it checks the connected hardware and updates the registry value automatically.

Reduce the number of programs running at startup computer.

Reduce the number of programs running at startup:

If your PC is taking too long to boot, it’s probably because you have far too many programs running at startup. Reducing this is easy, it will make your PC launch noticeably faster and lighter upon first load. To change the items running at startup, go to Run using the hotkey Windows key + R, and type “msconfig.” A small window will appear (see the screenshot below), select the Startup tab. From here you will be able to turn off many startup programs, which can shave several seconds (or minutes) off your boot time. (Note Windows 8 has moved this functionality to the Task Manager). Try to make sure you research what you are turning off as some processes might be needed by third party programs or drivers you have installed.
