With all of the new features of Windows Vista, there’ll be a mighty temptation for you to buy a copy of the operating system in a store and immediately install it over your existing instance of Windows XP, 2000, Me, or 98.
Before you do, you should consider some of the following cautions:
Your old PC may not be up to the challenge of running Vista. You may need substantial investments in additional RAM, a more capable video card, a larger hard drive, or all of the above to get adequate performance from Vista.
Some of your hardware, such as printers and networking adapters, may not work at all after you install Vista—unless you update the drivers they need to versions that are Vista-compatible.
Even if you find that one or more of your drivers needs to be updated, the vendor of your hardware may not make a Vista-compatible version available for months, years, or ever. (It’s happened before with previous versions of Windows.)
We do recommend that you get Windows Vista preinstalled when you’re buying a new PC. But you may be surprised to learn that we don’t recommend that you install Vista over XP or an older version of Windows.
The reason is that installing Vista on top of another version of Windows may cause incompatibility problems that you might not be able to easily fix. When you buy a PC with Vista preinstalled, it’s almost certain that the components in the PC will have been selected for their compatibility and will have the latest driver software. If you install Vista to an older machine yourself, however, you may find that your printer, networking adapter, or some other vital component no longer works because the version you have of its driver is incompatible.
In general, you shouldn’t consider installing Vista over an older version of Windows unless the following conditions are true:
• You need a feature of Vista that you can’t add to XP; or
• You need an application that requires Vista; and
• You can’t afford even the least expensive new PC that comes with Vista preinstalled
Even if one of the above cases is true, you may be better off burning your old data to a CD, formatting the old PC’s hard drive, and doing a clean install of Vista. This avoids the possibility that some components of the old OS will hang around to cause conflicts.
If you’ve never before backed up and formatted a hard drive, however, don’t try to learn how on any PC that’s important to you.
