If you can successfully boot into safe mode with command prompt (option 5 from Startup Settings blue screen), then try Steps 14-17 below and see if it works. If it does, you're good to go. If not, go through all steps. Tested on Windows 10 and 11. Steps: Get into Recovery Mode (blue screen): At the login screen, click the bottom-right corner Power Button. Then, before doing anything, hold down the Shift key. While holding Shift key down, click on Restart. This should reboot the computer and take you to the “Choose an Option” Recovery screen. If this doesn't work, see alternate later in post. If prompted, press F1 to enter Recovery Environment. If not, proceed to next step. Select Troubleshoot and/or Advanced Options until you get to a screen with a System Image Recovery option. Click System Image Recovery. Click Cancel on the "Re-image Your Computer" window. Ensure "Select a system image" is selected and click Next Click Advanced, then select Install a Driver and click OK. This gets you access to a Windows Explorer-type folder structure. Click This PC on the left side and find which drive has utilman.exe in the [drive letter]\Windows\System32 folder. The drive letter may not match your normal letters - this doesn't matter. Only one drive will have utilman.exe so you know you are in the correct one once you find it (my letters happened to match, except I had an X drive that wasn't useful). Rename Utilman to Utilman1. In this folder mode, you'll need to right-click and select Refresh to see the changes. Rename cmd to Utilman (refresh view to confirm both files are named properly). Close/cancel all of the open windows (close the Open window, click Cancel on the Add a Driver window, then close the last window) Click Continue from blue screen to reboot to your login screen. Click the Accessibility button on the login screen. A command prompt should open. (icon is a dashed clock at 3 o'clock for Win 10 or a person for Win 11) Type: "start msconfig" without quotes and press enter. The msconfig window should now appear. Select Normal Boot from the first tab and click Ok. Confirm restarting your system. At the next login screen, you should be able to enter your PIN and everything should be back to normal!! Now, you need to go back and rename Utilman to cmd and Utilman1 to Utilman (I had to follow steps 1-12 since Windows wouldn't let me edit the files while logged in). After re-completing step 12, you should be done. Other useful info: The default command prompt directory should be C:\Windows\System32. If that's not what's displayed, type "cd /d c:" without the quotes and press enter. Then type "cd c:\windows\system32" without quotes and press enter. Step 1 Alternate: Shut down your PC. Once powered off, boot it back up, then as soon as you see the Windows loading dots or windows logo, hold down your power button 5-10 seconds to turn off your PC.

Thanks so much for these detailed instructions. I attempted them and got to the System Configuration window where I changed that to Normal startup and restarted however there was no change in behaviour, ie still stuck in 'make a pin' loop. I attempted it again and noticed in the Boot tab of System Configuration window that the boot options are set to Safe Boot even though I've set a Normal Startup in the General tab. I attempted uncheck the Safe Boot and it said that BitLocker is enabled and it will enter recovery mode at the next boot, do you want to proceed. Which I hit Yes to. Then it said than it couldn't save the original boot config because a required privilege is not held by the client. So I'm afraid I'm still stuck in the loop unless anyone has a fix for this?

Guys If your problem about "Safe boot" do this first and do chatgpt what said. It works for me!

do Omid hosseini what said first.

Then do this: Chatgpt:
Hey bro, what you're dealing with is a classic Windows boot loop issue — but don’t worry, it’s not hopeless.

This will restore the original utilman.exe file and repair any modified system files.
