I was told by my security software company that my Windows 7 was corrupted and I should replace it. I purchased Windows 8.1 the other day. What will happen to my programs when I load it into the computer? Will I lose all of my installed programs? Can I copy them to an external hard drive somehow and install them once 8.1 is installed? Not terrific when it comes to compters but can install and uninstall. Not familiar with a lot of terms .
Simple instructions would be nice.
