This is Robert from Windows Live Messenger Technical Support.
I understand that you are always prompted to enter your username and password even though you have selected the options to remember these credentials. You tried to fix the issue by uninstalling some software on your computer but to no avail. I apologize if you had difficulty using this feature.
Please know that this is a known issue with Windows Live Messenger. Our product group is aware of this and is diligently investigating and working for a resolution. The fix is set to be rolled out on the next release of Windows Live Messenger.

Remember login and password information works fine until I restart the computer. means all goes fine when I exit the application and relaunch it again, it remembers the details. but when I restart the computer all get gone.
I have been facing this issue since some weeks, not only with Windows Live Messenger but all the windows live services that I am not able to save my login and password in the system. it also happens with any login form when I access it in the Internet Explorer. but other messengers like gtalk yahoo etc. are ok remembring my login detail and so the other browsers as well are able to remember the details.
I searched a lot on google since weeks but there is no any solution I found else than some I found on windowslivehelp.com but they were also not solved there instead hey recommended to consult with the help.live.com.
THINGS I HAVE TRIED:
I have tried uninstalling a couple of softwares like yahoo toolbar, google updater, outlook connector, windows live signin assisttant, some others. but the issue persists.
I would really be greatfull if you help in this regard. because I have tried every thing what I could do before asking it to you.
the problem is on more than one of my machines. that are up to date and virus protected.
Thank you very much
