Step 1. Press Windows key + X and select Command Prompt(Admin).

Step 2. Type "netsh int tcp set global autotuninglevel=disabled" and press Enter.

Step 3. Now try to transfer the files and check the data transfer speed.

Step 4. Again go to Command Prompt(Admin) and type "netsh int tcp set global autotuninglevel=normal" and press Enter. This will turn on the Auto-tuning again.

Method 3

Step 1. Open Control Panel and click on the Troubleshooting icon.

Step 2. Select View all in the top left corner.

Step 3. Run System Maintenance Troubleshooter.

Method 4

Turn Off RDC

RDC or Remote Differential Compression has a similar goal but it utilizes alternative ways to help you synchronize large chunks of data. It compresses the data during the network sync, but it can also be a drawback. That’s why we suggest disabling it. If the
problem isn’t solved, you can always re-enable it and move onwards through the list.

Here’s how to turn off RDC:

Step 1. In the Windows Search bar, type Turn Windows and open Turn Windows features on or off.

Step 2. Scroll down and uncheck the “Remote Differential Compression API support” box.

Step 3. Confirm changes.

Method 5

Disable Drive Indexing

In order to speed up the access to files stored on the local storage, Windows offers Drive Indexing. When enabled, this feature will index all files and substantially reduce the waiting time when you search for them in File Explorer. This is a great feature
if you have dozens of similar files which and helps you distinguish them and access them quicker than usual.

However, even though it should work when PC is idle, it sometimes doesn’t. And you can imagine how it can slow the data transfer if starts indexing files while the copying is still at hand.

For that reason, we suggest disabling it. At least temporarily. Here’s how to do it:

Step 1. Open This PC or File Explorer.

Step 2. Right-click on the partition you want to relieve of indexing and open Properties.

Step 3. Uncheck the “Allow files on this drive to have contents indexed in addition to file properties” box and restart your PC.

Method 6

Disable your antivirus

In a similar manner, as Drive Indexing can slow down copying, an antivirus might, as well. Of course, instead of indexing, it’s real-time engine might scan them for malware presence. Besides slowing down the transfer, it can also affect the whole system and
hog on the resources. Which adds up to an already heavy burden. That’s the reason why you should disable it until all files are transferred. Obviously, you would want to enable it afterward.

Here’s how to disable Windows Defender:

Step 1. Open Windows Defender Action Center from the notification area.

Step 2. Choose Virus & threat protection.

Step 3. Under the Virus & threat protection settings, click Manage settings.

Step 4. Toggle off Real-time protection.
