• 160GB Western Digital BLACK hard drive with Windows 10 Professional 64bit operating system (O.S.) preload. BONUS: Microsoft Word 2007 and Photo Shop 5.0 also installed. 
  • Compatible with many HP EliteBook and ProBook models.
  • All Drives are tested with Crystal Disk to be in Good working condition. The process I use to install Windows does not allow installation if a hard drive disk has any defects.
  • The WD BLACK series is a FASTER hard drive, spinning at 7200rpms, and is a higher quality hard drive.
[WD Blue is considered an all-rounder and is popular for basic, general purpose PC storage.

WD Black is one of the more expensive options due to its high performance. The high speed and large cache have made it the drive of choice for both home and enterprise desktop applications requiring heavy computing such as audiovisual content creation, rendering, and gaming.]

ACTIVATED with licensed key: O.S. has been installed onto the hard drive using an HP ProBook 6570b laptop, then activated with a licensed key. It has also been tested on an HP EliteBook 8570p, 8470p, HP ProBook 6460b. If you are using this in another HP Probook, with similar specs, it may already be activated for you. If not, just use the activation key on the bottom of your laptop (Windows 7 or Windows 10 Professional activation key), or purchase one. In my experience (I have installed Windows O.S. over 200 times on various laptops and computers), the O.S. should already be activated for you if you are using the same model computer, but sometimes you will need to activate. You may also find it to be activated on other EliteBooks and ProBooks. I have tested this hard drive on other HP EliteBook and ProBook laptops and found it to be working the same. Usually it is also already activated. You actually DO NOT have to activate it though in order to use Windows 10, you can still use it without activation, you just won't get anymore Microsoft updates.

ADDED BONUS: Other software programs preinstalled include:
1. Microsoft Office 2007
2. Adobe Photo Shop 5.0

Due to variations within the same, and different, laptop models, if a different driver is needed for a particular hardware device, all drivers can be downloaded from HP website for free.
