Make sure you have the disks
I do my best to support small local businesses, because I own and operate a small, local business. However, when it comes to purchasing a computer, too many times I have seen the small computer shop put together a machine that is more expensive with less features than a name brand computer. And worse, the computer does NOT come with the original Windows CD and accompanying license.
If you aren’t given and can’t obtain the original Windows installation disk when you purchase a computer, then the copy of Windows on your computer (and probably other software as well…think Microsoft Office) is illegal. The software will work fine, but when it comes time to reinstall after a hard drive crash or if you want to upgrade, you are stuck with having to purchase full versions of these programs.
