I have an HP Probook Windows 7 Professional Laptop and ARC works sweet as bro! That is Core i3

I know it's sad for all of us to see Windows XP disappear... but we have to remember that it is a thousand years old now. Even Windows 7 on a Windows XP built machine will run faster.

ARC is optimized big time. It is very efficient and tested on a very slow netbook with an old AMD processor and 2gb of RAM. Of course, the more you push the limits by adding more controls and scripting will require a faster processor. However, in many cases you won't need a very powerful computer at all. The AMD Netbook that I test on is super old and slow. And I mean unusably slow It can barely view our website! Yet, it runs ARC great

The reason for having to use Windows 7 or higher is due to the performance enhancements we use. In order to optimize the video processing and allow controls to continue running, the memory management of Windows XP cannot keep up. There just isn't the support in Windows XP to do what ARC requires...

This is because Microsoft has stopped supporting Windows XP a few years ago.

Windows XP was a good OS but I am also saddened it has said its ByeByes.

Ok, I installed windows 7 on my Toshiba netbook and its working good so far for my needs.

Putt Putt, Be more specific? Do you have processed video?

@PuttPutt that's good to hear. Windows 7 cures most problems for the reasons DJ mentioned. Professionally speaking, I always advise Windows 7 unless a client has a specific requirement for XP. I've never had a negative reaction to the upgrade.

@Rich, always good advice (nice to see your back )

Steve S , yes its working ok processing fine.
