Considerations

• While this laptop comes with Windows 7 Home Premium 64-bit Edition, if you've downgraded or bought the system used, you may need to upgrade. If you've got a 32-bit operating system, your computer will be able to use only 4GB, at most. The 64-bit operating systems typically can use your whole 8GB fully. All 64-bit versions of Windows XP though Windows 7 can use at least 8GB, excluding the Starter Editions.
