Sorry to not be clear.
But when i use RDP for example the websites where i do order can see it's windows serveur 2003, so see it's RDP then cancelled the order. Are there other possibilities to see that it's RDP ?
Maybe can talk on ICQ if you have free time
The reason the websites can see you are using windows server 2003 is because of user agent. Check for example http://whatsmyuseragent.com/ and you will see info about OS, browser etc. That information website can get also.
And switch to for example Internet explorer 9 and go to whatsmyuseranget.com site and check again.. they should then not be able to know you are on a server web browser.
No problem bro
There should not be any other ways for websites to see that you are using a RDP.
And with useragent/properly configured browser it will not even reveal information about OS so it will be fine. But of course you need to make sure that RDP are from same state as cardholders billing address etc.
You are right about java. Its a big security/privacy risk. I think its best to have java disabled or uninstalled. Maybe run Noscript addon to block it. I have never seen websites requiring java to order stuff. But some websites are using Flash which might do the same thing.
