Hi, good day!
To help narrow down the cause, could you please answer a few questions
Did this start after a Windows update or after installing any new software?
Does the duplicate bar appear in every File Explorer window, or only in a specific folder?
If you restart Windows Explorer from Task Manager (select Windows Explorer > Restart), does the duplicate bar disappear temporarily?
- If you open File Explorer in Safe Mode or create a new Windows user account, does the issue still occur?
Open File Explorer > click 3 dots > Options
Select View tab, under Advanced settings
Find and uncheck Show Status bar
Click Apply
Restart your computer
Go back to the same option and this time tick Show Status bar > Apply
I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.
