As long as you have a Mac computer, you can still log in to your Mac OS X and create a Windows password reset disk. After creating a reset disk, you can bring it to boot your locked Windows PC and remove your forgotten Windows password. Here are steps to create a Windows password reset disk in Mac OS X.

How to Create a Windows Password Reset Disk in Mac OS X?

1. Download the zip archive of Reset Windows Password onto your computer. Double-click the zip file to unzip. Check the extracted folder and you’ll find the ISO Image file: ResetWindowsPwd.iso.
2. Launch Disk Utility (Applications > Utilities).
   
3. Insert your blank DVD or CD.
4. Drag and drop the ResetWindowsPwd.iso file to the left pane in Disk Utility.
5. In the list on the left side of the Disk Utility window, you’ll now see an object representing the .ISO file. Click to select it.
6. Click on the Burn button. Sit back and wait while your new disc gets written!

Once the burning procedure is complete, you can then use the CD or DVD you’ve created to reset your forgotten Windows password. Here is the step-by-step guide:

How to Reset Lost Windows Password with a Password Reset CD

Note: please skip the step 1 in the guide above, because you’ve already created a Windows password disk in Mac OS X.

Note: We don’t in anyway encourage downloading Apple software via file-sharing / torrent sites and run it in an virtualized environment under Windows. This guide is for informational purposes only. If you like OS X Snow Leopard, Get a Mac.

Step 1: Download and install VMware Workstation 7.

Step 2: Click here to download pre-made modified version of Snow Leopard.vmdk and darwin_snow.iso files required to get this thing to work.

Step 3: Start VMware Workstation and open up “Mac OS X Server 10.6 (experimental).vmx” file which you downloaded in Step 2.

Step 4: Click on “Edit virtual machine settings”, select CD/DVD (IDE) option from left hand side and then and select “Use ISO image file” option. Point it to “darwin_snow.iso” which you downloaded in Step 2.

Step 5: Now power on the virtual machine and hit “F8” key. You should now have a screen similar to the one shown below.

Step 6: Now you’ll have to point your virtual machine to OS X Snow Leopard retail DVD instead of “darwin_snow.iso”. To do this, right click on CD/DVD option found in lower right most corner of your VMware window and select settings.

Insert OS X Snow Leopard retail DVD in your DVD drive and select the “Use physical drive” option.

Step 7: Now go back and select “c” option (Boot DVD) from the prompt which you got in Step 5 to boot from the OS X retail DVD. OS X boot screen with Apple logo should now appear. If the boot screen doesn’t appear for you, try booting it in verbose mode by pressing “F8” key after selecting “c” option, and then enter “-v” (without quotes). This will enable the system to boot OS X DVD using verbose mode.

Step 8: Wait for a couple of minutes for the Installation Setup screen to show up. From here on, simply follow the onscreen setup instructions to install OS X Snow Leopard. Make sure you format your virtual hard drive in “Mac OS Extended (Journaled)” format using Disk Utility. Customize your installation with minimum set of printer drivers and language options for a lightweight trouble free installation experience.

Step 9: Once the installation is completed. System will automatically reboot. At this point, close your guest virtual machine and change your CD/DVD option again like you did in Step 2 to point it to “darwin_snow.iso”.

Step 10: Start the virtual machine again. Press “F8” key and select “h” option to “Boot first hard disk”. Voila! Snow Leopard should now be running live under Windows 7!
