Upgrading to Windows 7 (part 4 of 4)

This final post in the series of upgrading to Windows 7, will describe how to do a “clean” upgrade.
If you need to do a clean upgrade, your hard disk will be wiped. Therefore you must re-install your applications as well as backup your data from the old Windows and restore it with Windows 7.

A clean upgrade would be worth the hassle under any of the following conditions [and maybe others]:
* You have installed and uninstalled many applications before.
* You have already upgraded from Windows XP to Vista previously.
* You want to use a 64-bit version and you are using a 32-bit version now.
* Your computer is running slow and it shouldn’t be with the resources you have.
* Your system was previously been infected with a virus or malware. A previous infection may still have something lingering in the system.

Tip: The Windows 7 DVD includes Windows Easy Transfer which will guide you on how to backup and then restore your data. It also gets installed in Windows 7.

Note: It is still good to do your own backup just in case Windows Easy Transfer misses something.

A full [non-upgrade] installation of Windows 7 should take normally between 30 and 45 minutes. Add time for a very slow computer. Doing a “clean” upgrade will last between 60 minutes and 90 minutes – longer for slower systems.

The legal way to do a “fresh” copy of Windows with an upgrade copy is the following:
* Install Windows 7 on a blank hard disk. You must wipe the hard disk first or it may think you are upgrading.
* During the installation it will ask you for a serial number. Do not enter the one found in the box. The number on the box is for upgrading in place. It will look and reject it if you enter it now. So keep the serial number location blank. Continue the installation.
* At the end of the installation, do not run and updates. Do not install and application. Do not restore any data.
* Now, if not inserted already, you will insert the DVD again and run an upgrade installation. You will upgrade on top of what you just installed. Must be in the same partition or drive [if more than one] and the same folder [i.e. c:\windows].
* When asked, you can now insert the serial number as the installer thinks you are doing an upgrade [even though you are going from most likely Home Premium to Home Premium]. Finish the installation. It will take longer than the first installation as it has to migrate your settings [even though you actually had none].
* After the installation ends, you can re-install your applications and restore your data.
* Activate once you are sure the installation of Windows was done correctly.

Note: This assumes you are legally entitled to upgrade to Windows 7 [i.e. you have a legitimate copy of Windows XP or Vista that you are upgrading from].

Note: By entering no serial number, the copy of Windows goes into a 30 day trial mode. Within the 30 days it should function as normal but will nag you regarding activation.
