I have been running Windows 7 64-bit RC since May on my other box. On the one I’m typing this on I’m running XP Professional 32-bit. Both boxes are capable of running Windows 7 64-bit and have multi-cored processors. – But I’m going to keep XP on this one for now; possibly right up to 2014 if the box lasts that long. – It should do as I built it, and the only ones I’ve ever had faults with that I built were a couple with a Shuttle mobo with a weak processor socket surround: Basically the AM2 cooler tensioniser lugs snapped off, and the cooler fell off the processor causing the machine to shut down when the CPU’s thermal trip activated. I RTM’d them and rebuilt. Also an AsRock mobo’s chipset died right in front of me as I booted up… This is going well off topic already.

There is a reason why I’m keeping XP for so long; which I’ll share with you further down.

For the time being; let’s take a look at Windows 7: -

When Windows 7 was subjected to benchmarking tests; the Office benchmark took more than 70% longer to complete with 7 than in Vista.

In the 2D multi-application test, this had a knock-on effect on the overall score. – Otherwise Windows 7 did prove faster than Vista – by around 2%. How, then, bearing that in mind, does this constitute a proper performance increase over Vista?

Windows Display Driver Model 1.1 is a new device in Windows 7 which allows multiple applications attempting to access screen-memory to draw and update their graphics at the same time. With the the 1.0 version in Vista only a single process could draw to the screen at any point in time, which was one of the reasons that Vista’s interface could sometimes seem uncooperative and sluggish.

Applications can update their windows as soon as you press a button in Windows 7,  Hence the system therefore appears to be much faster, while actual benchmarked performance is similar.

“But that doesn’t explain anything.”

In short, it’s all down to WDDM 1.1. : In Vista, display elements were stored in graphics RAM and system RAM at the same time. – Yet another waste of resources.

In Windows 7 with  WDDM 1.1 the data sets are stored in graphics RAM only. Therefore whilst this leaves more system memory free for applications, the down-side of it means that if the OS wants to draw graphics without going via the GPU, various data sets must be copied from video RAM to system RAM and back; thus wasting time.

This is the main downfall of Windows 7’s 2D performance in an office environment is actually worse than Vista’s, which we already know is slower than XP’s in that area. – Do you see where I’m going with this?

Everything else about Windows 7 is better, snappier, better laid-out and more functional with increased practicality. You’ll benefit from increased battery-life with 7 on your laptop or netbook. Yes even a netbook with 1GB RAM and a 1.6GHz Atom processor can run 7: It’s no gaming rig; but it does the business, and resuming from standby or hibernate is no longer a lottery as to whether it will actually start properly again when you do.

On your desktop, if you use 3D apps, games, memory-intensive processes, whatever, you’ll notice benefits immediately.. Office work, however, which I do a lot of on this particular box, pretty much to the exclusion of all else besides watching a video now and again, appears to have no benefits from 7, in fact quite the reverse by all accounts. – Which is way I’m keeping XP on this one.

What happens in 2014 when XPs extended product-lifecycle runs out? – Well if my calculations are correct we’re due another new OS around that time; so wait and see. I doubt this box will last that long in all honesty, talking from reality’s perspective: It’s in use one hell of a lot. – But even if it makes it to then; I’ll probably retire it on Linux, and build new for the next OS after 7.

Conclusion

So back to the question: Should I upgrade: –

Yes if possible; because Windows 7 has more snappiness and functionality than Vista or XP: It feels as if it’s working for and with you rather than begrudgingly for you as with XP, or against you as with Vista.

- But for your office computer; well there’s no rush. – Let’s leave it at that.

One thing for sure is that Microsoft have saved themselves from the looming pit of oblivion this time round.

Are you intending to upgrade to Windows 7? What machine do you have, and what is your current operating system?

Oh, and, when you upgrade, try to upgrade to the 64-bit version: There is just so much more to 64-bit computing – It really is “Life without walls”; such as not being restricted to 4GB RAM maximum for starters…
