TCPOptimizer on Windows 7 x64 Ultimate (7600)

[kishork]

Hi,

I ran TCPOptimizer on Windows 7 x64 Ultimate (7600).

Is it a mistake to do so on Windows 7?

my current TCPOptimizer settings mentions following :

I'll be interested in the response as well... Did it improve your speed ?

The main TCP Optimizer settings (RWIN) will not affect Windows Vista/7/2008 ... So you will not see a drastic difference as with XP/2k3/9x.

However, there are some additional registry settings that still work, so you may see some marginal improvement.

We do not recommend using the Optimzer under Vista/7/2008. Instead, we have a TCP patch and a tweaking article on the main site, see:
