Most people have heard of Windows Vista, which came between the venerable (and now discontinued XP) and Windows 7. At this point, no-one is buying a new PC with Vista on it. Almost all new systems are coming with Windows 7, and if you're looking at re-certified systems, you may see them using XP still.
We've had some clients that have bought or inherited machines with Vista, mostly because the systems they were buying (or the vendors they were buying from) didn't offer downgrade rights to XP.
So, is Vista right for your business's PCs? Well, maybe yes, maybe no. In the unlikely event that you're considering adding a machine that has Vista, the following are some considerations for you.
Of course, you could just skip this history lesson and head straight to our page on Windows 7 ...
The long and short of it is that Vista does have hundreds - actually, thousands - of improvements over Windows XP. The vast majority of those are things the average user will never encounter or recognize, or they're classed as "eye candy" by users and administrators alike.
Compatibility issues still exist with hardware and software, and the learning curve can be steep. So, in the end, if you're getting a new system and it comes with Vista, fine (just make sure it's a business version to work with your network). Go with it. If you can stay with Old Faithful XP Pro, stay. If you have the latest BusinessVision, go for Windows 7.
