Question details
The user needs to troubleshoot severe typing delays and screen flickering issues affecting Microsoft Office applications, specifically tied to Windows user profile corruption.
- Product
- Microsoft Word and Outlook 2021
- Device & OS
- Windows 11
- Scenario
- Typing documents in Word or composing emails in Outlook.
- Observed behavior
- The applications experience significant typing lag and continuous screen flickering within the window interface.
Before making changes to your Windows user profile, ensure you have enabled hidden files in File Explorer and backed up all important personal data to an external drive.
Migrate Files to a New Local Administrator Account
Create a new user profile to bypass the corrupted registry settings causing the typing lag and flickering in your Office applications.
Typing lag and screen flickering in Office 2021 are frequently caused by corrupted configuration files within your specific Windows user profile. Migrating your files to a fresh profile ensures a clean registry environment without affecting your installed programs.
Open Windows Settings, go to Accounts > Family & other users, and add a new user without a Microsoft account. Change the account type to Administrator.
Open File Explorer, click on the View tab (or View menu in Windows 11), select Show, and check 'Hidden items' so you can see all system files during migration.
Navigate to C:\Users\Old_Username. Select and copy all files and folders to C:\Users\New_Username.
During the copying process, ensure you strictly exclude the files named Ntuser.dat, Ntuser.dat.log, and Ntuser.ini to avoid transferring the corruption to the new profile.
Restart your computer and log in with your new local administrator account. Open Word or Outlook to verify the lag and flickering are gone.

Frequently Asked Questions
Why do Word and Outlook 2021 flicker and lag when typing?
These performance issues are often triggered by a corrupted Windows user profile, outdated graphics drivers, or conflicts with hardware graphics acceleration. A corrupted user profile specifically damages registry keys that Office applications rely on for smooth rendering.
Can I fix screen flickering without creating a new Windows profile?
Yes, you can try disabling hardware graphics acceleration first. In Word or Outlook, go to File > Options > Advanced, scroll down to the Display section, and check the box for 'Disable hardware graphics acceleration'. If the issue persists, profile migration is required.
Will migrating to a new user account delete my installed programs?
No, creating a new local administrator account and migrating your files will not uninstall your programs. Applications installed globally on the system, including Microsoft Office 2021, will still be available on the new account.
What happens if I accidentally copy the Ntuser.dat file?
The Ntuser.dat file contains your user-specific registry settings. If you copy it from the old corrupted profile to the new one, you will transfer the underlying corruption, meaning the typing lag and flickering issues will immediately return.
