Is anyone using the Arduino IDE in XP? Or willing to download about 100MB for a quick test? Just get the portable 1.8.9 version. Make a folder named "portable" in the same place as the .exe to avoid getting junk in your "Documents and Settings". Run arduino.exe and see if the CPU usage drops after it loads fully. It comes with its own Java and can't use the system JRE without recompiling. My issue is that whenever i start arduino.exe, which in turn starts the bundled javaw.exe, all my CPU gets hogged by the system services.exe process. This happens even when just sitting idle doing nothing. If i suspend javaw.exe, the CPU usage drops to normal. I tried to replace the bundled Java, but it doesn't start. Also tried to disable a few devices in Device manager (card reader, COM/LPT ports, etc.), but it doesn't make any difference. As a last resort i tried running it in a VM, but that was a fail as well. Recent Debian can't compile the Virtualbox 4.x drivers. Win7 in a VM is just as slow due to virtualisation overhead. My only working option currently is to every time reboot to Win7, do my arduino things, then reboot back to XP... The files used in Win7 are the same used in XP, yet the execution differs somehow.

Okay, I'm currently running Windows XP Home Edition with Service Pack 3 installed as a guest OS for a while under VMware Player and so far, I'm starting to experience some side effects to updating Windows XP. For some reason, while I'm using the 32-bit Microsoft Windows File Manager (found under \WINDOWS\System32\winfile.exe and originally taken from a Windows NT 4.0 SP6a installation), the CPU utilitisation spikes up between at least 85% to 100% and stays there until I terminate the process. Closing File Manager has no effect and the process remains there until I use either Process Explorer or the Windows Task Manager to close the misbehaving winfile.exe process. I believe that one of the security updates from June 2012 had a affect on this. I have provided a screenshot of what the problem looks like: How can I fix the problem regarding the excessive CPU usage running Windows File Manager?
