    • Click Clear to remove File Explorer history

  2. Delete Corrupted Cache Files

    • Press Windows + R, type %AppData%\Microsoft\Windows\Recent\AutomaticDestinations
    • Delete all files in this directory (some system files may remain—this is normal)
    • Navigate to %AppData%\Microsoft\Windows\Recent\CustomDestinations
    • Delete all contents here as well

  3. Restart Explorer Process

    • Press Ctrl + Shift + Esc to open Task Manager

Quick Alternative Solution

If the lag persists after cache clearing, disable Quick Access entirely:

  1. Open File Explorer Options (three-dot menu → Options)
  2. Change “Open File Explorer to:” from Home to This PC
  3. This bypasses Quick Access completely, eliminating cache-related delays

Method 2: Restart Windows Explorer Process

The fastest temporary fix for File Explorer freezing is restarting the explorer.exe process:

Using Task Manager

  1. Press Ctrl + Shift + Esc
  2. In the Processes tab, locate Windows Explorer
  3. Right-click → Restart
  4. All File Explorer windows will close and reopen automatically

Using Command Prompt

  1. Press Ctrl + Shift + Esc → File → Run new task
  2. Type cmd and check “Create this task with administrative privileges”
  3. Execute these commands:
    taskkill /f /im explorer.exe
start explorer.exe

Method 3: Disable OneDrive and Cloud Sync Applications

OneDrive integration frequently causes File Explorer performance issues through constant sync operations and file status checking.

Disable OneDrive Completely

  1. Press Ctrl + Shift + Esc to open Task Manager
