boot - How To Keep My Files After Rebooting?

I Wanted To Use Ubuntu From USB So I Burned The Iso File By Using "Rufus.exe",,

It Worked Fantastic! But There Is a Problem Which Is, If I Installed Google Chrome Browser For Example, I Can't Find It The Next Time I Boot From The Usb!

So How To Keep Everything I Install For The Next Time I Boot From That USB? Is That Possible Or I Have To Install Ubuntu Side By Side With Windows To Do It ??

You have to create a Live USB Boot Drive with persistence enabled.
