I recently installed the Windows 7 Enterprise 90-day trial on my old Compaq desktop with a 1.7GHz Intel Pentium 4, 1.2GB DDR RAM, 80GB HDD, and a Nvidia GeForce FX 5500 graphics card with 256MB dedicated video memory. The machine is running good, a lot better than I expected, having it dual booting with WinXP Pro. I have followed tutorials online on how to tweak Windows 7, such as TweakHound's guide, and I have also followed TweakHound's Windows 7 Freeware Machine guide. Its running pretty good, but not as fast as XP, which is what I expected. I just wanted to make sure that there weren't any tweaks/optimizations that I missed to make this computer run its best?
