Restrict access to Windows Vista with Parental Control Part 1

Parental Control - is a very powerful and easily used tool with which is very easy to prevent access by children or other unauthorized users to anything whatsoever.

Microsoft has not left unattended children. As part of Windows Vista is a very powerful and easily used tool with which simply prevent access to children or other unauthorized users to anything whatsoever. Any user with an administrator account can prevent ordinary users with a standard account downloads, access to certain games and applications, the ability to use a computer several times a day, and the like.

Of course, in this case deals with one new operating system and thousands of old programs, so be sure there are holes in the defense. The child does not need to be a super-hacker-ninja in order to gain access to where you think he's not allowed. For example, sometimes Vista does not recognize some of the games as games, and so we have to block them as regular applications. Further, parental controls in Vista relies on the User Account Control, and access to it restricted to only administrator account.

Parental Controls makes a blunder with some content and is not what should, for example, the ability to block playback of DVD-movies based on rating. So it is better to hide under lock and DVD with frivolous content.

Despite this, parental control are the most convenient means in order to protect the "foolish child" from unsafe content in Windows and, in some way, they can serve as a means of waste of time employees in the workplace in the form of games, or unlimited spending Internet - Traffic (subject to the use of Windows Vista, which has a parental control; note that Parental Control is not in the Windows Vista Business).

Parental control is easy to use, it is very accessible described in the help Windows Vista, so it makes no sense to describe what the button should be pressed to turn it on and tuning, but rather try to discuss what assistance should and should not expect this tool to administer the computer.

With Parental Controls, do's and don'ts

To use Parental Controls, you need a computer with Windows Vista, plus at least one account with administrator rights, and at least one standard user account. You must select Control Panel, then click User Accounts, and then - Manage another account. Here you can create or delete accounts.

Set parental controls can be in any standard account. Since the parental controls are mostly based on the User Account Control (User Account Control, UAC), it is impossible to manage user accounts with administrative rights - UAC in administrator accounts, sometimes requiring confirmation of any action, but to continue only one click. In the standard account UAC to confirm the continuation of action requires administrator password.


Thus, the first thing that makes the parental controls - it blocks everything that does not allow the User Account Control (UAC). This includes administration of user accounts, change settings, firewall, allow remote access to the system, change the system at any lower level, installing software and so on. UAC will interrupt any activity in Vista, where the icon is visible in the form of a shield, painted in the colors of Windows.

If you open parental controls, you can see that it allows you to afford. Parental Controls includes:

* Web-filter, which allows you to block certain Web - content. To enhance this function is the creation of black and white lists (lists of prohibited and permitted sites, the most practical method), or choose a different ban on objectionable content such as porn, bomb making, drugs, gambling and so forth. You can choose: allow or disallow sites rated and those that filter process failed;
* Time constraints, which allow you to set: at what time a standard user account has access to a computer;
* Control of games, with controlled access to games based on rating or according to personal preference;
* Control access to specific software to allow or deny access to any given program.

For example, using the Parental Controls, you can restrict access to any program, so if you do not want your child to chat with strangers through Instant Messenger or IRC client, you can disable. You can block access to any game at will, so that even if the game is rated ESRB (Entertainment Software Rating Board) "For all ages, you can still prevent access to it, leaving access to other games with similar ratings.

Web-filter works in close cooperation with Internet Explorer 7.0 +, Internet - the latest version of the browser built into Windows Vista. In other words, it does not work with browsers such as Firefox or Opera. You can, of course, deny access to these browsers, if they are installed in the system.

To use the time constraints can be filled with a temporary grid, describing access to a computer hour after hour. Grid signs for a week, so that, say, weekday access rules can be made more stringent than the weekend. But this tool is not so flexible as to prohibit access to a specific day, or somewhere else other than week to week and hourly.

Monitoring of games - one of the weaknesses. Parental control starts right from the window of the Games, where and define what games are available or not this or that account as rated, and by prohibiting preferences. Here we must be careful, because even though the Windows Vista built-in data directory of several thousand games, along with their ratings on the games that are not recognized as such, action Parental control does not apply.

For example, installed the game Battlefield 2142 has not been recognized as a game. Therefore, even with the prohibition of all games with ESRB rating higher than 10 +, Battlefield 2142 can not run under a standard user account. To prevent its launch, will have to consider the game as a routine application, and to block it in the control of access to programs.
