I used Windows 7 for couple of months now and I liked it. I liked the theme of Windows 7 which provides transparency at the edges of panels. But my PC is an old one and is very low-end. So the fancy graphics of Windows 7 slows my system to a great extent. Before updating to Windows 7, I was using Windows XP with classic theme. This wouldn’t consume resources of my PC. Now in Windows 7, the animation of Start Menu popping up lags a bit, the delay is easily noticeable. I search in the control panel for settings that will lower the details that are slowing down my system. I couldn’t find much that would help me. IS there any way I can apply the theme of old Windows OS like Windows 98 and 2000 on Windows 7. IS there any patch or mod available? Also if it is available can someone explain me its features that distinguish it from the original theme of Windows 7?
