Since you don't have that disk, we have to use a "backdoor" method to get you back into your computer. This involves using the Command Prompt from the recovery menu.

Phase 1: The "Accessibility" Trick

We are going to temporarily swap a background utility with the Command Prompt so you can reset your password from the login screen.

1. Enter Recovery Mode:

   • On the login screen, click the Power icon in the bottom right.

   • Hold down the Shift key on your keyboard and click Restart. Keep holding Shift until the screen says "Please wait" or "Choose an option."

2. Navigate the Menu:

   • Go to Troubleshoot > Advanced options > Command Prompt.

3. Identify your Windows Drive:

   • In the black box, type C: and press Enter, then type dir. If you see a "Windows" folder, you’re on the right drive. If not, try D: then dir, and so on. (Usually, it's C or D in this mode).

4. The Secret Swap:

   • Type the following commands one by one, pressing Enter after each:

     • copy c:\windows\system32\utilman.exe c:\ (This backs up the utility).

     • copy /y c:\windows\system32\cmd.exe c:\windows\system32\utilman.exe (This replaces the "Accessibility" button with Command Prompt).

5. Reboot:

   • Close the black box and click Continue to start Windows 11 normally.

Phase 2: Resetting the Password

Now that you are back at the login screen:

1. Click the Accessibility icon in the bottom right (the one that looks like a person in a circle).

2. A black Command Prompt box will pop up.

3. Type: net user and press Enter to see your exact username.

4. Type: net user YOURUSERNAME * (Replace YOURUSERNAME with your name. Keep the asterisk at the end).

5. Press Enter. It will ask you to "Type a password for the user."

   • Note: You won't see any characters as you type—this is normal. Type a new, simple password and hit Enter, then type it again to confirm.

6. Close the box and log in with your new password!

Phase 3: Getting the Picture Password Back

Once you are at your desktop:

1. Go to Settings > Accounts > Sign-in options.

2. You can now re-enable Picture Password using your new password.

3. Important: After you're in, you should repeat Phase 1 (Step 4) but swap the files back, or simply run a Windows Update to let the system "heal" that utility button.

Would you like me to explain how to undo the "Swap" once you've successfully logged in?
