It may be that I'm not optimised?

TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default TCP Receive Window (RWIN) = 65700
RWIN Scaling (RFC1323) = 2 bits (scale factor: 2^2=4)
Unscaled TCP Receive Window = 16425

In Windows 7, unless "TCP/IP Auto-Tuning" is disabled, only the Current TCP Window is displayed. Use the SG Vista TCP/IP patch instead of the TCP Optimizer for automatic tweaking.
RWIN is not fully optimized (even though it is a comparatively large number). The unscaled RWIN value is lower than it should be. Also, RWIN being close to and above 65535 does not justify the header overhead of enabling TCP 1323 Options. You might want to use one of the recommended RWIN values below.

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
64240 (up to 2 Mbit lines, depending on latency. MSS * 44)
128480 (1-5 Mbit lines, depending on latency. MSS * 44 * 2)
256960 (2-14 Mbit lines, depending on latency. MSS * 44 * 2^2)
513920 (8-30 Mbit lines, depending on latency. MSS * 44 * 2^3)
1027840 (25-60 Mbit lines depending on latency. MSS * 44 * 2^4)
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 2628 kbps (329 KBytes/s) @ 200ms
Your TCP Window limits you to: 1051 kbps (131 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 117 hops
TTL value is ok.
Timestamps (RFC1323) = OFF Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

I am clueless how to fix them in Windows7, so I hope someone can help. Please,

You can't and you shouldn't.
Win7 tunes itself on transfer speeds both ways. I used to tune WinXp but since Win7 has somenthing built in to adjust speed and since I have been using Win7 I'm very happy.
Here is an example.

who is speedguide analyzer anyway?

i think you should follow IggyAZ advice mate.

OK, I'll heed the advice, but how does Win 7 work it all out and is it actually proven to do the job?

If you can get 80% of your ISP's advertised data rates up and down during non-peak usage hours you don't need to tweak any settings. Win 7 (and Vista before it) handle all that stuff automatically, and do a great job of it IMHO.
