Use a USB Flash Drive to Lock/Unlock Your PC
Do you want to lock and unlock your computer with a physical key, like they do in the movies? With the free PREDATOR tool, you can! PREDATOR turns a USB flash drive into an access control device—a key for your computer. When you leave your PC, unplug the USB stick and your computer will be locked. When you return, plug it back in and your computer will be unlocked. It’s like using the Lock function in Windows, but you don’t have to type your password when you return. When you unplug your USB flash drive, your open windows will minimize, and your screen will go dark—plug it back in and your screen will turn back on.
Run Portable Apps Anywhere
One of the oddest things about the software is that it usually needs to be installed. With portable apps, however, that isn’t the case.
Portable Apps and games can be easily copied to a USB stick, then run from any suitable device. This is usually a 32-bit or 64-bit PC. Browsers, email tools, messaging apps, and games can all be run from a USB flash drive. It’s a particularly useful solution if you’re keen to keep a selection of apps close to hand to use on any PC that might be nearby. This might be in a library, or even a cybercafe at a holiday resort.
Install Almost Any Operating System
Bootable USB disk images of operating systems can be used to install a new OS on your PC.
For example, Windows 10 users can create a bootable USB installer disk using a dedicated tool. In the event of a problem with the operating system, this can be used to recover or even reinstall Windows. Similarly, all manner of Linux based operating systems can be installed from USB. Many offer a live environment, giving you get a feel for the OS which runs directly from USB before installation.
