Installing Patches on Windows 7 when logged in as user not administrator

[System Manager]

We are planning on deploying Windows 7 64-bit on staff computers and having them 
log in as user not as an administrator.  If they attempt to install Windows 
patches, they are prompted for the Administrator password, which they do not 
know.  Is there a way I can allow users to install Windows patches?  Do any of 
the patch management software packages solve this problem?
