1. Press Windows + R and open the Run dialog box
2. Type msc and press Enter
3. Scroll down and locate Optimize Drives

• DCOM Server Process Launcher
• RPC Endpoint Mapper

2. Perform System File Checker

System File Checker or SFC is a Windows 10 command which scans and identifies any impending errors and then delivers appropriate solutions. In case, the defrag facility is not working on your Windows 10 PC due to an error, the SFC command will scan for the error and help resolve it.
