c# - Check if Windows built-in local guest account is turned on -

i'm trying check determine if local windows guest account turned on or off. (please note different enabled/disabled, can check for).

as far can tell place the on/off setting has impact in local security policy setting "deny log on locally".

an acceptable workaround check can determine if built-in guest account capable of being displayed during log-in screen. question thing method needs know. in advance.

edit clarification:

this question answered averagejoeoftoronto on @ technet:

since i'm trying determine status of setting (as opposed editing it), solution provided export security policy using secedit.

secedit.exe /export /cfg %temp%\userrights.inf /areas user_rights /log %temp%\userrights.log 

produces cfg contain line relevant "deny log on locally" list:

sedenyinteractivelogonright = guest 

for lot of domain computers include aspnet (i recall seeing people looking same solution filter out aspnet). when aspnet or other accounts present output comma separated

sedenyinteractivelogonright = aspnet,guest,anotheruser 

averagejoe kind enough inform me policy can edited ntrights.exe available in windows resource toolkit.

if use post, please go on , vote answer @ technet apparently spent on hour looking solution. joe.
