Windows 10: Microsoft accoubt says my password is wrong on pc but the password works on mobile.

So recently i installed a new mother board and cpu into my computer, this forced my login pin to reset and asked me to login to my microsoft account. It kept saying my password was wrong so i reset it. This password works fine on my mobile but not on the pc which has effectively locked me out of my computer. System restore requires my password to initate command prompt requires my password. Im at a stand still. Again its asking me to sign in to the microsoft account not even password to open to the desktop.

How to reset Windwos 8 Password?

Change or reset your Windows password - Microsoft Support

• If you've forgotten your Windows password, there are several ways to retrieve or reset it:
  • If your PC is on a domain, your system administrator must reset your password.
  • If you're using a Microsoft account, you can reset your password online. ...
  • If you're using a local account, use your password hint as a reminder.

 

Wrong Password

The "Old Password" is the password to your local account. It is about to change your local account to a Microsoft Account. If you don't mind this, then enter your local account password. If you think this is overly intrusive of Microsoft, don't do it and let Cortana die.

 

Wrong Password

Kevin, it turns out that the "old password" refers to your Windows user password, not a Microsoft account password. In an effort to get people to create/use Microsoft accounts, Microsoft wants you to abandon logging into Windows with your Windows username and password, and instead use your Microsoft account username and password. Thus, if you're still using your Windows username and password to log into Windows, you'll have to enter this as the "old password" when enabling Cortana. The reason they call it the "old password" (while not telling you which password!) is that in addition to enabling Cortana, it will secretly in the background change your Windows logon to require your Microsoft account info instead of your "old" logon info.

Once I got through this, Cortana worked. I tried it out for a couple of hours, found it worthless, and completely removed it from my system (which is also not straightforward; there's another thread devoted to that).
