I use a pc with no indexing service no system restore ( i use acronis bootable cd instead) no themes or visual candy options on no unneeded services (9 service allowed including dhcp all other service are disabled) no antivirus ( just use stict security on xp, firefox or opera 4 browser, and a rule based firewall) no apps based firewall ( use a rule based firewall with policies on port, my choice is black ice defender (rule based firewall use less system ressource ) And use nlite ! My system is very stable, what mgadallah said about instability if you turn indexing of is not true My system is very fast my boot time from bios screen to windows is 8 sec. My system is fully fonctionnal, except for printer, but I dont have one, so i print virtually to pdf. If, like me you are a gamer, you should like this. look a a screenshot for system ressource:
