i want to speed up windows 10

The first thing you need to do is boot from the Windows bootable installer. If you are using a Windows 10 Creators Update bootable flash drive, simply plug the flash drive into your PC, restart the PC, then enter the boot option (the button to enter the boot option varies for each PC/laptop brand, please google if you don't know what the boot option button is on your PC), after that in the Boot Option select the USB Flash Drive. Besides using the boot option, you can also enter the BIOS/UEFI and change the first boot to the USB flash drive. The point is, make sure your PC boots from the flash drive containing the Windows installer. After that, Windows will ask you to press any key to enter the bootable flash drive. Once inside, you will be presented with a language selection, click Next. After that, click Install. You will be presented with a form to enter the product key. If your PC has previously been installed with an active Windows 10 whose license is recorded in Digital Entitlement, then you don't need to fill it in. Just click I don’t have a product key. Windows 10 will automatically activate again once the PC is connected to the internet and you log in to your Microsoft Account. However, if your PC has not previously been installed with active Windows 10 — and does not have a Digital Entitlement license, then enter the Windows 10 (retail) product key you have. Now you just choose whether to install Windows 10 Pro or Home. Click Next. As usual, check and Accept License Term, then click Next. Since our goal here is to reinstall (clean install) Windows, select Custom: Install Windows only (advanced). Now you will be presented with various partition options. Format drive C, where you will install Windows 10. Remember, all data on drive C will be lost after formatting. Click format to start, and click Next when done. The Windows 10 reinstall process will begin. Throughout this process, there will be several restarts, don't worry. This is normal during the installation process. After restarting, there will be several options. For the region, just choose Indonesia. For the keyboard layout, leave it selected as US. For the second keyboard layout, just Skip. Next, just choose Set up for personal use if you are reinstalling Windows on a personal PC. But if you are installing on an office or organization PC, choose the other option. And now it's time for you to log in to your Microsoft account. If you don't have one, just choose Create Account and register. Enter the Microsoft account password. After that, set a PIN for login. This PIN will make it easier for you to log in. Instead of using a long password, using a PIN will be simpler and easier. Enter the PIN you want. There is an option to use Cortana or not, just choose Yes. Then there are privacy options, you can turn off what you want. But it's better to turn On and Accept all so that Cortana's features and relevance run optimally. All setup and settings are complete. Now you just have to wait for the Windows 10 installation process to finish. Done. Finished. That's how to clean install Windows 10 Creators Update. Very easy, right?
