When you're pretty addicted to trying new applications like we are around this part of the web, our machines quickly become victims of heavy digital battery. To safeguard our computers, it's always a good idea to use portable applications whenever possible. The application in question cannot store program settings or make changes in the Windows Registry so it poses little to no danger to our systems. However, the selection of portable applications may not always include a lesser-known or new application that we desperately want to test out, so the next best thing is to test drive them in isolated environments.
You might think it's extra work to isolate these applications because you always keep your antivirus software updated and won't ever think of downloading obscure software anyway. Yet practicing this type of caution by using special isolating software will likely be more beneficial in the long run. Having a computer overrun by viruses will not only be hair-splitting, but may also lead you to spend money to replace a machine that could have perfectly lived longer.
