Windows 7: How to set session duration limit ? Via Parental Control ?

How to set duration session limit?

For instance, after 1 hour of active session, the session is blocked for the following hour.

Thanks.

P.S. Following sets possible time of use for instance from 8h00 till 21h00, but does not prevent an all day usage !
Parental Controls - Set Time Limits

You should be able to block an entire 24 hour period or multiple 24 hour periods. For example, if you wanted to prevent computer usage from 12noon on Saturday until 7am on Monday (that's 43 consecutive hours of no access) you'd block off the boxes highlighted in yellow.

No you don't understand.

I want to allow for instance usage between 9h00 and 20h00; but within that period I don't want more than 2 hours of usage !

You're right. I'm confused. Sorry.

For example, you want two hours of total usage between 9am and 8pm (9h00 and 20h00.) How do you want those two hours of usage set up? You can only do it in one hour blocks with Parental Control. If you're trying to do 30 minutes here, 15 minutes there, 1 hour and 15 minutes some place else, it won't work.

But there are other free programs that are more flexible. Such as:

Timeout | Romaco Canada

If I'm still not getting it my deepest apologies.

Thanks for answering !
Maybe I didn't express myself in a clear & unique way !

Many thanks !
From a functional point, seems totally what I'm looking, hope is not full of adware and won't slow my PC down.

P.S. Do you know in parental control how de-active other browsers than Chrome (esp. IE9); as my quick test about porn shows, that Chrome locks the search in "safe search mode" and is effective, while IE9 sometimes let porn thumbnail preview, which Chrome does NOT.

Try this:

1. Open Control Panel > Internet Options
2. Click "Content" tab
3. Click "Enable" under "Content Advisor"
4. You should now see different categories like "Nudity", "Sexual Content", etc
5. Drag the slider menu to "None" to specify what computer users are allowed to see
6. Click "Apply" and then "OK" to save your settings

3. Click "Enable" under "Content Advisor"

4. You should now see different categories like "Nudity", "Sexual Content", etc

I don't see that, I see Web Filtering(sliding from green list to authorise adult content), and although I already had selected "public websites(Blocking adult sites)", still with IE9 I do see porn thumbnails.

In IE9, just type "suce ma bite" then on results page(already text content is explicit), choose "images" or "videos" to display videos or images and you'll see explicit blowjobs; with Chrome you don't!
