I think people are getting a little carried away here.
I think Windows has probably stabilized enough by now to run for a month at a time without crashing. Although you do realize that approximately 52,325 Windows Security updates will have probably come out over that timespan, and that Windows almost always demands a reboot to apply them?
1GB of RAM sounds rather cramped. I'm not even sure that Windows 8 is rated for that small a configuration. I also had to suppress a laugh about "all other uncessary services & app will stopped". Thanks to such stealth features as RUNDLL and its friends, there's a lot of services hiding in Windows.
I did just retire a 1GB Linux machine that hosted PostgreSQL and a
Tomcat server, although it would have been happier with 2GB. A lot depends on your workload, though.
And, of course, factor in environmental considerations. A UPS is virtually essential even in places where power is supposedly continuous. Computers these days can take a fair amount of heat, but even so, a certain amount of air conditioning is wise. 30°C or lower at least (that's what I run). If your humidity is too low, static electricity can be an issue, if it's too high, condensation can mess things up. And. of course, if you're subject to a lot of sand and grit in the air, some filtering is advised. You're probably well-versed in what things to allow for when running computers in your part of the world, but make allowances for the lack of "recovery time".
