We tend to move and copy tons of files on our PCs and mostly, the process of copying or moving files, especially if the file has the size of 1GB or up, tends to take quite long. This may be caused by some issues which is why you face slow copy or move speed. So if you are experiencing this issue on your Windows 10 computer, then read on as this post will give you a couple of solutions you can try to increase the speed in copying or moving files. Follow the given instructions below.

Option 1 – Try to change the USB port

You might want to change the USB port since modern computers have a variety of USB ports. So if your USB drive supports USB 3.0 or 3.1, make sure that you plug it inside a USB 3.0 or 3.1 ports. If you’re not sure which port, just keep in mind that the USB 3 port is usually blue or you can also use your computer’s documentation or manual as a reference to locate it. It may sound nothing but changing the USB port can actually improve the copying or moving speeds drastically so this should be the first thing you can try to speed up the process of copying or moving files.

Option 2 – Update the USB Controller Drivers

You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 4 – Try to disable Windows Auto Tuning

Disabling Windows Auto-Tuning can also help in increasing the copying or moving of files in your computer. It is said that this feature improves the performance of programs that receive TCP data over a network by adjusting the receive buffer size dynamically throughput and latency of the link. Thus, if you are trying to copy some data over the network, then the Auto Tuning feature is playing a role here. And in some cases, disabling this feature completely resulted in a lot faster copy speeds over the network.

Option 5 – Try changing the USB Removal Policy

• First, plug your USB drive or external device into your PC and then open This PC.

• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 2 – Try purchasing a new license

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Option 3 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.
