CLEAN INSTALL OR UPGRADE?
When you upgrade your copy of Windows all of your files, data and programs will remain intact. However not every version of Windows 7 will allow you to upgrade. You cannot upgrade from any copy of Windows XP and you cannot upgrade from a copy of Windows Vista that is a higher product edition to the version of Windows 7 you are installing. For example, you cannot upgrade Windows Vista Ultimate to Windows 7 Home Premium.
The best advice is always to make sure all your files and data are backed up, see the Guaranteeing chapter of this book for how to do this, and do a clean install. This will make sure you get the fastest, least problematic installation possible. Upgrading can cause any problems you currently have with your copy of Windows to also exist after the upgrade to Windows 7.
WINDOWS 7 EDITIONS
As with all editions of Windows, Windows 7 comes in different product versions. The ones you'll encounter will be Starter,Home Premium, the most common edition and Professional for advanced systems and businesses.Ultimate will contain every feature.
The benefits of Windows 7 over XP and Vista
I have Windows XP :
Windows 7 is considerably more secure and safer to use on the internet than Windows XP. For this reason alone you should consider upgrading to Windows 7. Use the upgrade checker on the Microsoft website to see if your PC will run it.
I have Windows Vista :
Windows 7 fixes almost all of the performance issues that caused Windows Vista to run slowly. The security system, User Account Control (UAC) is also now considerably less annoying. Any PC running Windows Vista will happily run Windows 7.
UPGRADING FROM WINDOWS XP
Windows 7 will not allow you perform an in-place upgrade from any edition of Windows XP, trying to do so will give you an error message. On the Windows 7 DVD is a program called Windows Easy Transfer that you can run in Windows XP (and Vista) to back up out files and settings to another location, either an external hard disk or another partition, that can later be restored after performing a clean installation of Windows 7. Getting Started in the Start Menu has an option to restore this.
UPGRADING FROM WINDOWS VISTA
You can perform an in-place upgrade from Windows Vista. The following versions will allow an upgrade depending on what editions of Vista and Windows 7 you are upgrading from and to...
UPGRADING FROM OTHER VERSIONS
Windows 7 will not allow upgrading from other versions of Windows. This includes all versions before Windows XP (Windows ME, Windows 98 etc.) and all versions of Windows Server
WHAT IS 64 BIT WINDOWS?
Each edition of Windows 7 comes in two flavours, 32 bit and 64 bit. The edition you have will be printed on your install DVD. Most new PCs now come with the 64 bit version of the operating system pre-installed, however there can be a downside.
While the 64 bit versions of Windows offer better security and stability, there is still hardware and software that won't run on it.
64 bit operating systems are slightly faster because of this.
Windows 7 also includes additional security functionality that makes the 54 bit version of the operating system more secure.
On the downside older hardware and software might not be supported. For best results run the Windows 7 upgrade checker and check with a manufacturer's website for your hardware to see if 64 bit drivers exist
32 or 64 bit?
The difference between 32 and 54 bit software is the size of the numbers the PC can do calculations on.64 bit operating systems are slightly faster because of this.
Windows 7 also includes additional security functionality that makes the 54 bit version of the operating system more secure.
On the downside older hardware and software might not be supported. For best results run the Windows 7 upgrade checker and check with a manufacturer's website for your hardware to see if 64 bit drivers exist
UPGRADING FROM 32 TO 64 BIT
Windows won't allow you to upgrade in-place from a 32 bit version of Windows to a 64 bit version, nor will it allow you to perform an upgrade the other way around. To change between these versions you will have to perform a clean install.
CLEAN INSTALL FROM UPGRADE ONLY PRODUCT KEY
It is possible to perform a clean install of Windows 7 with a product key that will only allow you to upgrade it.
To do this do a clean install Windows once without entering a product key, it will allow you to do this. Now run the installer again and perform an upgrade over the clean install you have just done. Your product key will now be accepted as valid for installation.
