How to reset/find my W7 Pro Password?

This may be a "common" problem but I do not know how to deal with this! I have a laptop and I have forgotten my Windows 7 Professional Password for my Administrator Account, though I could log in to my other non-Admin accounts O.K. Worse of all I have not created a "Reset Password" disc/USB device therefore there is NO way I could instruct W7 to reset my Admin's Password as it keeps complaining about a previous "Password Reset" disc is NOT found.
So would there be a way, either through some genius Freewares or other means, that would enable me to log in to my Administrator Account and subsequently reset my Admin Password please?? Or I may need to send it back to my laptop Supplier to do something about it??

Thanks

Hi, thank you for the reply! I was busy recently and could not see your post in time. I have seen the link that you provided and there is a piece of "free" SW that may do it for me. I will try that "carefully" for my Windows 7 Professional password reset for my laptop.
Thank you once again!!

be careful changing passwords like this if you have encrypted folders

I realise it may be risking ALL my previous Adminstrator's "encrypted folders" becoming unreadable IF I change its password like that. However, what else can I do if I can not log-in to undo the encryption in the first place. By the way, my laptop does indeed have account dependent "encrypted folders", which means the risk that you have highlighted could be real! Thanks

Thank you for your suggestion! After a few inquiries I am sure that I have never enabled Encryption in any of my Folders or User accounts, which means I will not lose any encrypted folders, since they don't exist in my laptop, even I intend to reset/remove Password. I have found some Free SWs through other user's recommendations which could do what I wanted.
Thank you for your suggestions anyway!

Thank you for your link and the recommended SW! Indeed I just purchased this V4 SW and been successfully removed my forgotten password in Windows 7 with no other complications at all. It is a very useful SW but that said I'm now having second thought about the general Password Security of my Windows OS since it is proven easily "cracked" for abnormal use!!!
Thanks
