A deep copy makes a completely new independent copy of an object, including copies of any other objects it references. In a shallow copy, only references to other objects are copied, so the copy and the original may both reference the same object. The copy is not a completely separate duplicate. Google "deep copy vs shallow copy" for the language you're using. There are a lot of websites you can visit for information and examples.

I forgot my deepfreeze and i need to delete it tho it can't be deleted without unfreezing my pc i tried antideepfreeze and it failed for me ....what can i do ?


There's no possible way to recover a lost/forgotten Deep Freeze password. But there are several ways to possibly disable/uninstall DeepFreeze.

Enterprise Version :
Deep Freeze Enterprise users can generate One Time Passwords (OTP) to gain access to deepfreeze. To generate an OTP,
  1. Open the Deep Freeze login dialog on the system for which you need to generate the One Time Password.
  2. Write down the Token code. It is located at the top of the login dialog.
  3. Open the Deep Freeze Configuration Administrator and click the One-Time Passwords tab or open the Enterprise Console and click on Tools > One Time Password.
  4. Enter the code you recorded into the Token field and click Generate OTP. Another code will appear in the OTP field. The second code is the password for the workstation.

The newly generated One-Time Password can then be used to disable, uninstall, and re-install Deep Freeze with the correct password.

For Deep Freeze evaluations (with no License Key entered) :

  1. Restart the computer.
  2. Enter the system BIOS settings.
  3. Advance the clock by at least 60 days and then restart your computer. This will disable the software.
  4. After the system has started, run the Deep Freeze installation program to uninstall Deep Freeze.
  5. After the computer reboots, re-enter the BIOS and reset the clock to the current date. You can then re-install Deep Freeze after restarting.
If you are running a licensed copy of Deep Freeze Standard submit a ticket and we can look into the issue further to see if there are any other options avalalbe to assist you.

How to uninstall deep freeze


To uninstall the software Deep Freeze must first be disabled and then uninstalled.

To disable Deep Freeze:

1. Hold down the shift key and double-click on the Deep Freeze icon. Alternatively, you

can press Crtl-Alt-Shift-F6. You should now see a password dialog.
2. Enter your password and click OK. If you have not yet entered a password you should be

able to click OK without entering anything. You should now see a dialog with boot options.
3. Select "Boot thawed" and click OK. This will disable Deep Freeze on the next reboot.
4. Reboot your machine. After the machine reboots you are ready to uninstall Deep Freeze.

To uninstall:

1. Locate the installation file you used to install Deep Freeze to this machine. By

default the name of this file is called "DF5Std.exe" for versions 5.X and "DF6Std.exe" for

versions 6.X.
2. Run the installation file (DF5Std.exe or DF6Std.exe).
3. Select the option to "Uninstall"
4. The software should uninstall and reboot the machine. When the machine reboots, Deep

Freeze should be uninstalled.

You require Norton AntiVirus from a disc as a clean boot will be required due to the virus "hiding" in the RAM.

I tried to make an exact copy of a CD via Sony Vaio but the copy is messed up. Certain cuts sound scratched. The original CD is clean and plays normally. Does my CD drive need fixing? It (software)...


What type of CD did you copy? Different CD types have different methods for copying them (Example: a music CD has multiple tracks to copy; better to rip them then reburn them onto a blank disk; a DVD disk has multiple data, video and audio files protected on the disk, a straight copy wont work). Based on your question, you tried copying a music CD. Use a program like Windows Media Player, RealPlayer, or iTunes to rip the disk, then copy the ripped tracks to a blank disk. All three of these programs are free, and there are tons of other free alternatives out there to do this.

System backup


Essentially the same.
A good backup is a copy of any data you wouldnt want to lose in the event of hard drive failure, theft, fire, etc. A copy of your important data on another medium such as external hard drive, flash drive, cd, dvd, network drive.

I dont consider a floppy a reliable medium, dont use those.
A copy of your data to another partition on the same physical hard drive is NOT really a true backup.

The best is to back up (copy) your important data to a reliable and known good medium and store it in a different location than your original data. Different location meaning, not in your house, but in someone else's house.

Back up today what you dont want to lose if your hard drive goes up in smoke tomorrow. Simple as that.
