How To Fix Cortana, Can’t Log Into Microsoft Account In Windows 10

Reader Question:
“Hi Wally, I’m trying to set up Cortana with my Microsoft account but whenever I try to register my account, it says that my account is already there. I’ve tried using different user accounts but Cortana doesn’t work with any one of them. I’m using Windows 10 Enterprise edition.” – Whitney P., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: Windows 10 has received a fairly positive response from its users so far. According to Microsoft’s own statistics, 75 Million activations of Windows 10 took place in the first 30 days of its release. Even though many people are happy with their copy of Windows, there are some users who have experienced problems like this. However, most of these problems are easy to solve.


Cortana isn’t working in Windows 10 Enterprise. Unable to get Microsoft account registered with Cortana. It gives an error message saying that:

[account name] is already here.


Here are some ways to fix the Cortana login problem in Windows 10:

Remove All Other Microsoft Accounts

Windows 10 has this problem with Microsoft accounts which doesn’t let you use a login/account for domain purposes once it has been added. You can remove this account from Windows using the registry editor. Once removed, you can add it again using Windows 10 settings and menus.

  1. Press Windows Key + R > type regedit > press Enter
    Windows 10 - Cortana - Windows Key R - regedit -- Windows Wally
  2. In the Registry Editor, click the arrow next to each category to expand it. Go to StoredIdentities using the following address:
    Windows 10 - Cortana - regedit - StoredIdentities -- Windows Wally
  3. Do you see the account that you want to log into here? Right-click it and click Delete.
  4. Press the Windows Key > click Settings > click Accounts
    Windows 10 - Cortana - Start Menu - Settings menu - Accounts -- Windows Wally
  5. Delete all existing accounts.
  6. You should see a blue Add a Microsoft account link at the bottom of the screen. Enter login details to add a new account, and you’re done.
