When trying to login to windows sometimes I remember during the login that I used the wrong password. Windows then tries for a very long time to check the wrong password if it is correct.
Description of the proces.
How can I cancel/stop the login process when I remember I used the wrong password?

Cancel windows login ony works with RDP.
For your situation there is no such option, but you can always disconnect the cable.
Try to shutdown your internet connection from either a WiFi switch or any laptop has dedicatd funcional key to switch to airplane mode (Usually it can be turned off by pressing and holding Fn button and then press functional button that has antenna sign, usually it F8 but can be different depending on make and model)
In the cortana's search bar paste following string rundll32.exe keymgr.dll,KRShowKeyMgr, then this shameless lady should found : "Stored User Names and Passwords Box", highlight it and click Enter. You should get a window with saved credentials and one of them should be Windows live. On the right side you can choose appropriate action to that record (Remove/edit)
