I have installed JRE 1.7.0_04-b22. I disabled the "update" setting in administrator - update requests disappeared, but in ordinary user's account it is nagging me about updates and I can't turn it off. The "update" tab is grayed out. When I run javacpl.exe with administrator rights, it changes the global setting:
HKLM\SOFTWARE\Wow6432Node\JavaSoft\Java Update\Policy\NotifyDownload HKLM\SOFTWARE\Wow6432Node\JavaSoft\Java Update\Policy\NotifyInstall
but then can't use it in ordinary user account.
