I just installed Windows 7 Ultimate 64Bit SP1. Was using Windows 7 Ultimate 64Bit and now i came to know that SP1 or later upgrades suffers from the disease called Svchost high memory usage. I did tried to resolve it as Microsoft stated but that didn't worked. I did disabled the windows update manually and through services.msc but that's not a permanent solution either! All i want to know is that why does it occurs ? What if i install Windows 7 Ultimate SP2 or Windows 8 ? (I would like to stick with Windows 7) Help me out Geeks!
