How to fix errors in Microsoft store [7q6ca]

Hi Sage B,

Thank you for reaching out to the Microsoft Q&A Forum. I understand how frustrating it can be to run into a sign‑in error, especially when you’re trying to switch profiles.

Here are the suggested steps to resolve the issue, please try these steps in order. After each step, you can check whether sign‑in works as expected before moving on.

1 - Sign out and remove existing Microsoft accounts from the device

• Open Settings > Accounts > Email & accounts
• Under Accounts used by other apps, remove any Microsoft accounts listed
• Go to Access work or school and disconnect any accounts shown
• Restart the device
• Try signing in again using only the account you want to use

2 - Refresh Microsoft Store sign‑in data

• Press Win + R, type wsreset.exe, and press Enter
• Wait for Microsoft Store to open automatically
• If needed, go to Settings > Apps > Installed apps > Microsoft Store > Advanced options, then select Repair (or Reset if Repair doesn’t help)

3 - Clear stored sign‑in credentials

• Open Control Panel → Credential Manager
• Select Windows Credentials
• Remove credentials related to Microsoft, Office, Azure, or OneAuth
• Restart the device so fresh credentials can be created automatically

If the issue continues, please try creating a new Windows user profile, this is a reliable way to confirm whether the original profile’s settings are causing the problem.
