How to install software onto a pen drive?

Oh!! Let"s see what we can do oh!! Ya there is one thing

See at home ( I am expecting you are trying to put a game on your school computer )

1) during the install at home when it asks just change the file directory to the pen drive from c drive

2) when it asks you to create a desktop shortcut say yes

3) take that shortcut in your pen drive (simply copy to your pen drive )

4) simply stick the pen drive in and doubleclick your shortcut to run the programme

Cons 1) may require additional allowing or admin permition

2) usually these software files tend to use more than 4gb of space easy so using a cheap pen drive and getting away with it won't be that easy

3) and the last and the biggest con the pen drive is USB 3.0 it might work without problem but if USB 2 then problem at most times as the transfer rate is not fast enoughf any how does not matter usually for small software include counter strike

       Tell me if it helped.                The end.
