Har annars kört detta själv någon gång om man inte lyckas öppna cmd som admin via windows:
Force shutdown the PC when the windows logo displays on startup. You can do this by switching off from your UPS or mains power switch. (This works on desktop but I haven't been able to confirm on a laptop.) Do this another 2-3 times until the PC launches into 'Startup Repair' menu. (This is the only method that works as launching startup repair through Settings>Update & Security>Recovery>Advance Startup will prompt for an admin password when you try and access CMD)
When startup repair launches, click on the 'Troubleshoot' tab > Then click on the 'Advanced Options' tab. > Then click on the 'Command Prompt' tab.
When command prompt opens, type 'notepad'.
When notepad opens, Click on the 'File' drop-down menu > Then click 'Open' > Then open 'This PC' > Then open your local drive.[It will most likely it will be Local Disk (C:) but in startup repair, it will be moved a letter down and renamed Local Disk (D:) due to the boot drive temporarily taking the position of Local Disk (C:)]
When you open your local drive open 'Windows', then open 'System32'. Ensure that it searches for 'All Files' and not just '.txt' files. Then find the executable file called 'sethc' and rename it the 'sethc-old'. Then find the executable file called 'cmd' and rename it to 'sethc'. ['Sethc' is the executable for the accessibility feature called 'Sticky Keys'.]
Then exit Startup Repair and start the PC as normal.
When the logon screen appears, click the 'Ease of access' button which is to the left of the Power button then switch ON the 'Sticky Keys' option. Then press the 'Shift' key five times quickly and CMD should open with Administrator Privileges.
From here you can do pretty much anything if you're familiar with command line (CMD) commands.
8. If not you can enable the hidden admin account by typing net user administrator /active:yes then give the new admin a password by typing net user administrator * then confirm the password and voila! Close CMD and you can now login to the hidden admin account. You can access and manipulate any account other on the PC to your will.
I wasn't sure what flair to give this post so forgive me if 'Bug' doesn't suit it.
