...after 097292fe "Add HKEY_CURRENT_USER
registry integration" added "winuserreg:".

Even though changing from the exisiting "winreg:" to "winreg:LOCAL_MACHINE"
should be compatible, as it only ends up in fundamental.ini included in the LO
inst set, play it safe it keep treating "winreg" the same as
"winreg:LOCAL_MACHINE".

("url" is a misnomer now in configmgr's Components ctor, and should eventually
be renamed to something more accurate.)
