Quote from Bob111:
Sorry MSFT, but I'm not buying it. What's wrong with 3rd party antivirus/firewall and browsing with a common sense ?
Likely correct. Some people are still using Windows 2000.
XP for a trading machine should be OK for at least a few years... if it's dedicated for trading, connected only to servers used in trading... and not used to surf the net or adding other programs. If one is worried about getting corrupted or compromised, perhaps should get a 2nd computer with W7/8 for general computing and keep it up to date with AV and patches.
