Jokes Home : Technology : How often to Reboot
How often should a computer with XP-SP2 rebooted?
That depends entirely on what you have on it. If the machine is near stock, with McAfee VirusScan and Firewall, and just used for business, with spreadsheets, word processors, databases and normal Internet access for bill paying and shopping, then once or twice a year is plenty.
If the machine has Norton on it, and a dozen tweaks and utilities and toolbars and similar stuff, then once an hour is good, unless it crashes before then.
