Welcome Daniel Fuller
From what you shared, I understand you set up a new Windows PC using an incorrect user account and are now trying to fix the username and associated sign‑in connections.
Before moving forward, please create a system restore point. The restore point helps you revert if something goes wrong or you don’t like the changes.
After that, please check if it's a Microsoft account or local account via: Settings > Accounts > Your info.
If you see an email address (for example, ******@outlook.com), you’re using a Microsoft account; otherwise, it's local.
1. For Microsoft Accounts
Microsoft accounts sync your display name across devices and services (email, OneDrive, etc.), so changes here update connections automatically.
- Microsoft accounts sync your display name across devices and services (email, OneDrive, etc.), so changes here update connections automatically.
- Go to Settings > Accounts > Your info
- Select Manage my Microsoft account (this opens account.microsoft.com)
- Open Your info > Edit name, enter the new first and last name, complete the CAPTCHA, and save
- Sign out and sign back in (or restart) to apply the change
- This will update the name shown on the sign‑in screen and in apps, and refresh account‑linked connections.
2. For Local Accounts
- Use Control Panel for a clean change without cloud sync issues.
- Search for "Control Panel," go to User Accounts > User Accounts > "Change your account name."
- Enter the new name and click "Change Name." Restart to apply.
Fix Connections Post-Change:
- OneDrive & apps: Sign out and sign back in to affected services so they pick up the updated name.
- User folder: The profile folder name doesn’t change (for example, C:\Users\OldName). If needed, create a new account via Settings > Accounts > Family & other users > Add account and migrate your data.
- Fully restart the PC to ensure all changes sync correctly.
Hope this helps. Please let me know how it goes or if you need further clarification!
