Scattered in with the omnidirectional praise for Windows 7 is a seemingly-big, often-discussed bugaboo: not all Windows users upgrading to the new OS can do an in-place upgrade to the Windows 7 version of their choice. This fact has sparked some of the only complaints aimed at the new OS, and generally speaking, I agree with the main point: an in-place upgrade should be an option for more users.
But should they use it? More on that later.
In case you’re wondering, an “In-Place” upgrade is one where you have Vista installed on your PC, pop in the Windows 7 upgrade disc, and wait while the Win7 installer copies new files over old, giving you a new OS without having to reinstall programs or backup and restore data. In short, an In-Place upgrade is Vista one minute, Windows 7 the next (well, within the next few hours). Every file and program is right where it was before.
The basic rules for in-place upgrades are these: (1)If you have XP, no in-place Win7 upgrade for you. (2) If you have a version of Vista installed, you can in-place upgrade to that same version of Windows 7; so, for example, with Vista Home Premium 32-bit installed, you can do an in-place upgrade to Win7 Home Premium 32-bit, but not Windows 7 Home Premium 64-bit or Windows Business. And (3) you can upgrade any version of Vista to Windows 7 Ultimate, but only to the same bit version (32-bit Vista Anything to 32-bit Ultimate, 64-bit Vista Anything to 64-bit Ultimate). See the chart above for further clarification (click to enlarge).
Any Windows 7 installation that does not fit condition 2 or 3 must perform a “Custom Install.” A custom install is just a clean install, and here (finally) I come to the point of this article:
Unless you have some specific reason for not doing so or are a Level 1 novice user, bite the bullet and do a clean – or custom – install of Windows 7 on PC, even if you can do an in-place upgrade.
Why? Two reasons (mainly).
General Cleaning & Maintenance. After years of use, PCs accumulate a lot of files, registry entries, software configuration files, update installers, performance logs, crapware, etc. Doing a fresh install of Windows every year or two keeps things running smoothly and gets rid of junk you don’t use, and in many cases, don’t need. A new OS release is the perfect opportunity to do a little digital cleaning.
Stability. Upgrading from one OS to another is a major to-do. This is one reason Microsoft offers such limited in-place upgrade options. There’s a lot of work involved and many, many possibilities for errors, failures and mishaps. When you do an in-place upgrade, files and configurations are jiggered. A clean install puts everything right where it ought to be, just how it was intended by the designers, leaving you with a pristine experience (at least from a software point-of-view).
Now for the bad(ish) news: just because a clean install is better doesn’t mean it’ll be easy – it’s a lot of work. You must backup your files, make a list of all the applications you need to re-install, deactivate software tied to user accounts (like iTunes), etc. But the work pays off in the end because you slim down, get rid of software you installed and ran once back in 2007, and un-clutter things all around.
If you must do, or choose to do, a clean “Custom Install,” Microsoft has even created a tool called Windows Easy Transfer which can copy your files and settings to an external hard drive, then copy them back once Windows 7 has been installed. You will still have to re-install software, though.
So if you can’t do an In-Place upgrade to Windows 7 on your PC, don’t be sad – be glad. A clean install will be better for you anyway because your computer will run better for years to come.
As is so often the case in life, this problem is, for many users, a lucky break.
