http://blogs.msdn.com/securitytipstalk/archive/2007/02/19/use-windows-vista-to-help-enforce-limits-on-your-children-s-computer-use.aspxThis week we highlight a special feature of Windows Vista Parental Controls —time restrictions. If you're a parent, you know there’s more to guiding your children’s computer use than shielding them from inappropriate content or contact with strangers.enCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/securitytipstalk/archive/2007/02/19/use-windows-vista-to-help-enforce-limits-on-your-children-s-computer-use.aspx#2670531Wed, 16 May 2007 14:06:28 GMT91d46819-8472-40ad-a661-2c78acb4018c:2670531CSMR<p>Great feature this. Using other products, it's always tricky to set things up so they can't be defeated, so having secure parental controls based on UAC is great.</p> <p>Do you know if there is work being done to make it more advanced, or if third party companies are making use of this technology to provide more advanced controls?</p> <p>Specifically the one-hour period is quite long, it would be nice to have finer intervals, 30,20,15 or 10 minutes. Also having time-limits (certain amount of time one can use the computer in a day) is a popular request.</p>http://blogs.msdn.com/securitytipstalk/archive/2007/02/19/use-windows-vista-to-help-enforce-limits-on-your-children-s-computer-use.aspx#3026037Fri, 01 Jun 2007 18:09:33 GMT91d46819-8472-40ad-a661-2c78acb4018c:3026037Marcelle Amelia<p>Thanks for the great feedback. We forwarded it to the parental controls team.</p> http://blogs.msdn.com/securitytipstalk/archive/2007/02/19/use-windows-vista-to-help-enforce-limits-on-your-children-s-computer-use.aspx#7801436Tue, 19 Feb 2008 22:59:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:7801436keona1995<P>Parental controls are a great feature, but for some reason it has stopped working on one particular computer, since about February 13, 2008. The error message is "Unable to change parental control settings. If this situation persists, see your system administrator." My account is the system administrator. No settings can be changed now. Security Event logs are showing an Audit Failure having to do with an unknown user or password. The time correlates to when the Parental Controls applet was started. It is as if UAC no longer understands that the administrator account is indeed an administrator. Created a new administrative account, but the result is the same. I don't have the exact logs since I am not at home, but it appears that beneath the indicated administrative account there is a blank SID and blank Administrator line. Again, this seems to indicate that the account has lots its association or proxy for the Administrator account. </P>http://blogs.msdn.com/securitytipstalk/archive/2007/02/19/use-windows-vista-to-help-enforce-limits-on-your-children-s-computer-use.aspx#8343446Sat, 29 Mar 2008 16:10:36 GMT91d46819-8472-40ad-a661-2c78acb4018c:8343446Nikkita<p>My son is able to access by right clicking and viewing the control panal then access parental controls and change the time limits. how can I stop him from accessing the parental controls please?</p>
