TeamViewer Portable is capable of providing technical support by sharing access to a users' desktop while also providing the ability to transfer files and create screen captures. The application relies on computer IDs and passwords which can be set up easily by following easy directions. Essentially, it's the same as the original application but it does not require installation you can run it from virtually anywhere including USB memory sticks and thumb drives. With that, we have a portable version of TeamViewer which requires no installation. There are tons of different remote desktop sharing applications available on the web, but TeamViewer still seems to be one of the most popular.
