We just announced that we formally support Property Intellect on Windows 7 from the 3.1.8 build (i.e the current build at time of writing). I’ve been playing with a ‘Release Candidate’ version for a little while now, but decided to go out and buy a copy and upgrade my Dell laptop (which had Vista on it, which I was not keen on). I wiped the disk and reinstalled from scratch to give it the best possible shot, and I’m glad I did! Initial reaction: installed quickly and easily and starts up/shuts down much quicker. The responsiveness of the laptop is also very noticeably better.
I’m impressed. Effortless install, big performance boost and zero crashes thus far. It recognised and installed all required drivers (I might just have been lucky on that front though). It’s hard to see how one can ask for more really.
Next step – upgrade my main working PC…could be much more challenging…let you know how it goes 
I have to agree with you on this Mr Barton! Having spent many years using not just windows operating systems, and all the problems getting to a stable XP edition. Then followed by the tragedy that was Vista, I thought I would upgrade to Windows 7 on one of my machines, just out of curiosity more than anything else.
It has been the best install of windows I have ever done, MUCH faster to install than Vista, much cleaner RAM, (Less than HALF compared to a clean install of Vista!!). The system is clean and neat and fast. Very impressive stuff.
Also with its nice little extras such as the shake function (select and hold the top bar of any window and shake the mouse. all other windows are minimised. repeat the action and they all return. )
The task bar is also a great improvement, from simply ‘quick view’ of windows (just roll your mouse over the item in the bar), so rearranging the programs on the task bar (something I have longed for many years). even the ‘Show desktop’ is much better positioning at the far bottom right, to allow a quick view of the desktop, or quick selection without having to position the mouse over a little button, and keep bringing up the start menu instead!
Thoroughly impressed with windows 7!
Can’t wait to try PI on my new and fast system!
I’m pretty much impressed with the stability of Windows 7. It is better than windows Vista which hogs my memory and cpu.;’-
