Impossible activate parental control

Hi all,
hope this is the right section of the forum.

I can't seem to be able to activate parental control on my windows 7 64 Home Premium (Microsoft Security Essential installed), because every time I try to click on an user account to activate parental control, an error window pop up saying


"Impossible modify settings for parental controls. If the problem persists, please contact system administrator."

Needless to say, the problem persists and I can't seem to be able to do anything about it.

My copy of windows ofc is original.

Thanks!

Hello, thanks for implying I am an idiot

I am logged in as admin of course, but the problem remains the same. I have even tried to create another admin account, then modifying parental controls settings with the new admin account, but to no avail.

On the link you reported there is written that "For Parental Controls to work, it needs to have the Parental Controls Service set to its default setting of enabled and Manual." Now, I went into the services panel, but I can not find any parental control setting for windows 7, I mean the only entry of parental control says "The service is a stub for parental control services already present in Vista. It's provided only for compatibility with previous versions", and activating this service does anything for me.

Maybe this can be the problem?

Hey! Thanks for your welcome and thanks (both!) for answering me :)

Would you mind telling me if the description of your parental control service match mine? Because my entries are in italian, and I just want to make sure we are speaking about the same service. Mine says something along the line of "The service is a stub for parental control services already present in Vista. It's provided only for compatibility with previous versions" (translated from italian, so the exact words will be a little different).

The right settings I assume are as in you picture, with status = null and startup type = manual, correct?

Tried both solutions, neither worked

It's like something went wrong when Windows "installed" the parental control, isn't there any way to reinstal them w/o having to re-install the whole OS?

the /scannow command didn't really help, as twice in a row it couldn't find anything broken. I will try the repair install stuff, though as it seems to take some time I'll do it in the week-end, and let you know.

Thanks! :)
