Windowsda kullanici login zamanlarini limitlemek

Gecenlerde basima gelen bir olay:
+ kardesimin butun gun WoW oynamasindan dolayi sigortalari atan peder bana gelip
su bilgisayarin acilma zamanlarini sinirlandirmak istiyorum dedi.
Bunun uzerine ufak capli bir arastirma yapip su olayi buldum:

net user username  /times:logon_times

/times icin parametreler su sekilde olacak:
Use the following information to help you use the /times switch:
• Days can be spelled out (for example, Monday) or abbreviated (for example, M,T,W,Th,F,Sa,Su).
• Hours can be in 12-hour notation (1PM or 1P.M.) or 24-hour notation (13:00).
• A value of blank means that the user can never log on.
• A value of all means that a user can always log on.
• Use a hyphen (-)to mark a range of days or times. For example, to create a range from Monday through Friday, type either m-f, or monday-friday. To create a range of time from 8:00PM to 5:00PM, type either 8:00am-5:00pm, 8am-5pm, or 8:00-17:00.
• Separate the day and time items with commas (for example, monday,8am-5pm).
• Separate units of "day and time" with semicolons (for example, monday,8am-5pm;tuesday,8am-4pm;wednesday,8am-3pm).
• Do not use spaces between the days or times.
