how are you sending this link?
IM(MSN,AIM,ICq[this still exist?], ect?)?
email? Windows does not need a default mail client with web based e-mail, you can just use hotmail/gmail/insertmailname.com here to send links(see below.)
Generally if you want to send a link, you can just copy and past the link right from a browser.
So lets say i want to send this page to someone.
Up the the address bar select it all with the mouse and hold control + c to copy it(or right click and select copy)
Open an email, msn, or forum thread and past it with control + V or right click in the text field and hit paste.
hope this helps a bit.
