Windows 10: Can't login after clean boot

I followed the steps here https://support.microsoft.com/en-us/topic/how-to-perform-a-clean-boot-in-windows-da2f9573-6eec-00ad-2f8a-a97a1807f3dd to clean boot, but I forgot to check Hide All Microsoft Services. Now when I get to the login screen I see "Something happened and your PIN isn't available. Click to setup your PIN again." Clicking set up my PIN does nothing. By holding shift + clicking restart I go to the troubleshoot menu where I have tried startup repair which fails. I also tried booting from a windows installer usb which startup repair also fails with. Booting into safe mod

:)

List your specs out and tell us each step in cleaning you did.

 

Clean Install Workaround for Vista

You may remember this news story on techPowerUp! a couple of days ago relating to the lack of clean installs when using the Upgrade Editions of Vista, which required an old OS to be installed. However, Paul Thurrott has managed to find a workaround for this issue, which ironically lets users do a clean install Vista without any previous version of Windows, albeit a little tedious. Here are the steps:

• Boot from the Windows Vista Upgrade DVD as normal
• When prompted for a product code, leave this blank
• Select the version of Vista you have purchased and let Vista install
• When you boot to your desktop for the first time, run the Vista setup from Windows
• This time enter your product key
• When asked whether you want to do an Upgrade of Custom install, select custom and choose a clean install
• Windows will now install for a second time and you should be able to activate it

Remember, these steps are only advised for use in order to achieve a clean install of Vista, it is only legal to use the upgrade editions if you have previously purchased the appropriate version of Windows.
