Building my first build and I was going to go with the Win7 Home Premium OEM version when a "salesman" asked me with CPU I was running. I told him the 2600K. His reply was you should get the Pro version of Win7 as it will run faster and utilize your CPU better. Is this truth or was this gentleman simply trying to increase the sale.
What is the difference between the OEM, and the Retail version of Windows 7
There are 3 major differences between these 2 items. The physical DVD disks themselves contain exactly the same content.
1. OEM copies of Windows Vista come in either 32, or 64 bit flavors. You must decide which version you want, and make sure you purchase that copy. With a retail copy, you get both 32 and 64 bit Windows Vista DVD’s in the same box.
2. OEM copies cannot be transferred from one PC to another. Once you install an OEM copy of Windows Vista on a PC it must remain with that PC forever, unless upgraded to a newer version of Windows in the future. Retail versions can be moved from PC to PC, but your retail copy of Windows Vista cannot be installed on more than one PC at any given time.
3. OEM copies do not come with any support from Microsoft. If you need to call Microsoft for support with Windows Vista, you must pay a fee to do so. Retail copies come with a phone support incident included in the price.
