Warning to Parents: How to Bypass Time Limits in Windows 7

   Posted by Lê Hoàng in Windows 7

Parents contact me everyday with concerns about children accessing the computer without their permissions. This demonstrated technique shows one method that kids use to hack the parental control time limits in Windows 7.

This is one of the methods that your children may be using to hack and bypass the parent control time limits.

Before we get started make sure you have an USB (512MB at least).

You CAN’T use Hiren’s boot 11 to perform the trick since this version has removed some cool softwares that we need. We recommend the 10.6 version.

Since your account is limited, it will be better if you can do from step 1 to step 7 of part 1 on other computer (maybe your friend’s computer)

On your friend’s computer:

1. Download Hiren’s Boot 10.6 (the download link is at the bottom of the page, direct Http mirror) and extract the zip file.

2. Now, you have options to burn the Iso file to a CD or to copy those files inside the Iso to the USB and boot from it. (We choose the USB option because it takes less time and it cost you nothing! If you already have a Hiren Boot CD, please skip to part 2 below).

3. Now, download and extract these 2 files: usb_format and grub4dos.

4. Plugin your USB, lauch usb_format.exe and do as shown below.

5. Lauch grubinst_gui.exe and do as shown below.

6. Use a tool to extract the ISO file (We use 7z). Go to HBCD folder (inside the Hiren’s.BootCD.10.6 folder) and copy grldr and menu.lst to your USB.

7. Copy all contents inside Hiren’s.BootCD.10.6 folder to your USB. Now, it will look something like this:

On the blocked computer:

1. Start the computer and plug in your USB (or insert your Hiren’s Boot CD).

2. Hit Delete (or similar key, it all depends on your mainboard) at the first screen to enter the BIOS. You need to configure your BIOS to boot from USB (or CD) as the first device. (because we use different BIOS, we will not guide how to configure the BIOS settings here. Doing some Goolge search will help ;) )

3. Save all your BIOS settings and restart the computer. When the system boot from your USB (or CD), choose DOS Programs (CD version may not have this).

5. Go to Password and Registry Tools.

6. Choose Active password changer.

7. Press 1 and Enter to choose your logical drive.

7. When the SAM search process is done, press Enter to continue.

8. Choose your limited account’s number and hit Enter.

9. Ok, so when you see the screen below, simply press Page Down on your keyboard to change permitted logon hours.

10. You will see a screen like this with less spaces (Our test account has been blocked all hours). Use your arrow keys and SPACE to check on that hours.

9. After that, press Y to save all settings and restart your computer. You will be able to log into your account at ANYTIMES! (Even at blocked hours).


You will notice that your parental control profile hasn’t changed a bit! (You can see it from the Parental Control Panel in taskbar that your blocked hours are still there!) This happen to your administrator account too. (When children use this technique, you will never know that they have bypassed the time limits settings. )

You may also see the countdown timer at the taskbar. When it reaches 0 hrs and 0 min, it will automatically countdown from 0 hrs and 59 mins and will repeat as needed.

    Why not just password protect your bios and prevent booting from USB? You then lock the case so the kid cannot open the case and reset the bios. Then there should be no way to boot the computer using the method you suggest.

    Why not just change the system time – to a time you would be allowed to go on.


    • December 14, 2010 at 3:30 am, Anonymous said:

      Yes. But you must do it through BIOS and it will affect the time in all user accounts.

      With a normal user account, you can’t change the date and time while parental control is turned on :)

    I was thinking of bios but I was also thinking of RATing my own computer, and using it to control the administrator, or possibly using a Brute forcer. Wish I didnt have these stupid limitations, if they weren’t there I wouldnt have to go through the trouble of doing this.. -.-

    Thank you for a good bios, but maybe because my restrictions aren’t quite so constricting I can actually do some of this through command prompt… ;-) thanks for the help

    Using HBCD is it possible to change account types?

      > no, it is not possible.

    For some reason, pressing Y gives the message “User’s attributes has not been changed” Any idea why this is happening and how to fix it?

    Just gonna put this out there…. but there is a MUCH easier way of bypassing the time limit. Upon startup, press f2 or whatever to enter the BIOS, then just change the system time to a time that is allowed. TADA, took only 30 seconds.

      > and you do that if you have only 1 hour allowed?

      He give us something to have unlimited time, and you mustn’t always change time.

    Hey i booted my pc up with the cd with the program and when i had to enter the active password changer it didnt have the option it only had 1 to 6, ( 6 being de back option)

    When I try to boot kon-boot, the system asks if I would like to start windows normally. So this method does not work anymore! I have windows 7.

      > it work, but I think that you did an error

    changing the system clock in bios settings works for me. :) thats the best and easiiest way. Im not sure if that works for everybody.

    sigh…i wish i could do this…i just dont understand that much of it…i desperately need the timer off my main computer…this one im on since the timer is up on the other one, this one is a peice of ish


  16. March 08, 2013 at 9:35 am, Brandon said:

    So will the settings revert when the USB is out? And will it change the system files forever?

  18. May 04, 2013 at 10:30 am, Joseph said:

    or you could press f2 (or f12, f9, depending on your PC) and change the time and when the time limits are over change the time back to (time allowed in parental controls)

    Hello, I’m block on the 8 th step on the blocked computer.

    Whenever I use this to disable the time restrictions, loads of programs don’t work which use Java, just comes up
    “No JVM couldbe found on your system please define EXE4J_JAVA_HOME to point to an installed 32-bit JDK or JRE or download a JRE from http://www.java.com

    There is no [boot] folder I see on my USB.
    On step 6 you said extract ISO file. What do I have to extract exactly?


  23. January 25, 2014 at 12:02 pm, Li-5 said:

    It didnt work for me. I have done all the step even after I changed the log on time it still present me from log on resstriction time. And in my USB I dont have the BOOT folder. Is this why it didn’t work?
    I don’t even have that folder after I have extracted ISO.


  24. January 25, 2014 at 9:13 pm, Li-5 said:

    It didn’t work for me because neither I don’t have the BOOT folder in my nor maybe active password changer 3.0 don’t support win 7
