Summary

By adjusting TCP Auto-Tuning, optimizing the Optimize Drives service, and disabling Remote Differential Compression, you can significantly improve file transfer speeds on your Windows 11 PC. These simple tweaks help enhance your device’s performance, ensuring faster and more efficient data transfers.

• How can I improve my file transfer speed on Windows 11?

  Increase file transfer speeds by adjusting the TCP Auto-Tuning level, optimizing drive service settings, and disabling Remote Differential Compression API Support.

• What is the TCP Auto-Tuning level and how does it affect file transfer?

  TCP Auto-Tuning optimizes data transfer over networks. Adjusting its level can improve or reduce file transfer speeds, depending on your system's configuration.

• Can optimizing the Optimize Drives service impact file transfer speeds?

  Yes, setting the Optimize Drives service to automatic and starting it can enhance the performance of your HDD or SSD, indirectly speeding up file transfers.

• Why might I want to disable Remote Differential Compression API Support?

  Disabling this feature can improve local file transfer speeds by preventing the system from only sending data differences, which might slow down direct transfers.

• Is it necessary to back up data before making these adjustments?

  Absolutely, creating a restore point or backing up essential files is crucial before making system changes to prevent data loss in case of errors.
