Windows 10 October 2020 Update

The Update Assistant can help you update to the latest version of Windows 10. To get started, click Update now.

Create Windows 10 installation media

To get started, you will first need to have a license to install Windows 10. You can then download and run the media creation tool. For more information on how to use the tool, see the instructions below.

Here’s when to use these instructions:

• You have a license to install Windows 10 and are upgrading this PC from Windows 7 or Windows 8.1.
• You need to reinstall Windows 10 on a PC you’ve already successfully activated Windows 10.

If you are installing Windows 10 on a PC running Windows XP or Windows Vista, or if you need to create installation media to install Windows 10 on a different PC, see Using the tool to create installation media (USB flash drive, DVD, or ISO file) to install Windows 10 on a different PC section below.

Note: Before you install Windows 10, check to make sure your PC meets the system requirements for Windows 10. We also recommend going to the PC manufacturer’s website for any additional info about updated drivers and hardware compatibility.

1. Select Download tool, and select Run. You need to be an administrator to run this tool.
2. On the License terms page, if you accept the license terms, select Accept.
3. On the What do you want to do? page, select Upgrade this PC now, and then select Next.

After downloading and installing, the tool will walk you through how to set up Windows 10 on your PC. All Windows 10 editions are available when you select Windows 10, except for Enterprise edition. For more information on Enterprise edition, go to the Volume Licensing Service Center.

• If you don’t have a license to install Windows 10 and have not yet previously upgraded to it, you can purchase a copy here: https://www.microsoft.com/en-us/windows/get-windows-10.
• If you previously upgraded to Windows 10 on this PC and you’re reinstalling it, you don’t need to enter a product key. Your copy of Windows 10 will automatically activate later using your digital license.

When Windows 10 is ready to install, you’ll see a recap of what you’ve chosen, and what will be kept through the upgrade. Select Change what to keep to set whether you would like to Keep personal files and apps, or Keep personal files only, or choose to keep Nothing during the upgrade.

Save and close any open apps and files you may be running, and when you’re ready, select Install.

It might take some time to install Windows 10, and your PC will restart a few times. Make sure you don’t turn off your PC.

Follow these steps to create installation media (USB flash drive or DVD) you can use to install a new copy of Windows 10, perform a clean installation, or reinstall Windows 10.

Before you download the tool make sure you have:

• An internet connection (internet service provider fees may apply).
• Sufficient data storage available on a computer, USB or external drive for the download.
• A blank USB flash drive with at least 8GB of space or blank DVD (and DVD burner) if you want to create media. We recommend using a blank USB or blank DVD, because any content on it will be deleted.
• When burning a DVD from an ISO file, if you are told the disc image file is too large you will need to use Dual Layer (DL) DVD Media.

Check a few things on the PC where you want to install Windows 10:

• 64-bit or 32-bit processor (CPU). You’ll create either a 64-bit or 32-bit version of Windows 10. To check this on your PC, go to PC info in PC settings or System in Control Panel, and look for System type.
• System requirements. Make sure the PC meets the system requirements for Windows 10. We also recommend going to the PC manufacturer’s website for additional info about updated drivers and hardware compatibility.
• Language in Windows. You’ll need to choose the same language when you install Windows 10. To see what language you’re currently using, go to Time and language in PC settings or Region in Control Panel.
• Edition of Windows. You should also choose the same edition of Windows. To check what edition you’re currently running, go to PC info in PC settings or System in Control Panel, and look for Windows edition. Windows 10 Enterprise isn’t available in the media creation tool. For more info, go to the Volume Licensing Service Center.
• Microsoft Office products. If you just purchased a new device that includes Office 365, we recommend redeeming (installing) Office before upgrading to Windows 10. To redeem your copy of Office, please see Download and install Office 365 Home, Personal, or University on your PC. For more information, check How to upgrade to Windows 10 on new devices that include Office 365.

If you have Office 2010 or earlier and choose to perform a clean install of Windows 10, you will need to locate your Office product key. For tips on locating your product key, check Find your Office 2010 product key or Enter the product key for your Office 2007 program.

Using the tool to create installation media:

1. Select Download tool now, and select Run. You need to be an administrator to run this tool.
2. If you agree to the license terms, select Accept.
3. On the What do you want to do? page, select Create installation media for another PC, and then select Next.

Select the language, edition, and architecture (64-bit or 32-bit) for Windows 10. This table will help you decide which edition of Windows 10 you’ll choose:

Your current edition of Windows	Windows 10 edition
Windows 7 Starter Windows 7 Home Basic Windows 7 Home Premium Windows 7 Professional Windows 7 Ultimate Windows 8/8.1 Windows 8.1 with Bing Windows 8 Pro Windows 8.1 Pro Windows 8/8.1 Professional with Media Center Windows 8/8.1 Single Language Windows 8 Single Language with Bing Windows 10 Home Windows 10 Pro	Windows 10
Windows 8/8.1 Chinese Language Edition Windows 8 Chinese Language Edition with Bing	Windows 10 Home China​

Select which media you want to use:

• USB flash drive. Attach a blank USB flash drive with at least 8GB of space. Any content on the flash drive will be deleted.
• ISO file. Save an ISO file to your PC, which you can use to create a DVD. After the file is downloaded, you can go to location where the file is saved, or select Open DVD burner, and follow the instructions to burn the file to a DVD. For more info about using an ISO file, see Additional methods for using the ISO file to install Windows 10 section below.

After the installation media is created, follow the steps below to use it.

After completing the steps to install Windows 10, please check that you have all the necessary device drivers installed. To check for updates now, select the Start button, and then go to Settings > Update & Security > Windows Update, and select Check for updates. You may also wish to visit your device manufacturer’s support site for any additional drivers that may be needed.

Note: Drivers for Surface devices may be found on the Download drivers and firmware for Surface page.

Before you install Windows 10, it’s a good idea to save any work and back up your PC before you start. If you used the media creation tool to download an ISO file for Windows 10, you’ll need to burn it to a DVD before following these steps.

1. Attach the USB flash drive or insert the DVD on the PC where you want to install Windows 10.
2. Restart your PC.

If your PC does not automatically boot to the USB or DVD media, you might have to open a boot menu or change the boot order in your PC’s BIOS or UEFI settings. To open a boot menu or change the boot order, you’ll typically need to press a key (such as F2, F12, Delete, or Esc) immediately after you turn on your PC. For instructions on accessing the boot menu or changing the boot order for your PC, check the documentation that came with your PC or go to the manufacturer’s website. If you do not see the USB or DVD media device listed within the boot options, you may need to reach out to the PC manufacturer for instructions for temporarily disabling Secure Boot in your BIOS settings.

If changing the boot menu or order doesn’t work, and your PC immediately boots into the OS you want to replace, it is possible the PC had not fully shut down. To ensure the PC fully shuts down, select the power button on the sign-in screen or on the Start menu and select Shut down.

On the Install Windows page, select your language, time, and keyboard preferences, and then select Next.

Select Install Windows.

If you downloaded an ISO file for Windows 10, the file is saved locally at the location you selected. If you have a third-party DVD burning program installed on your computer that you prefer to use for creating the installation DVD, that program might open by going to the location where the file is saved and double-clicking the ISO file, or right-click the ISO file, select Open with and choose your preferred DVD burning software.

If you want to use the Windows Disk Image Burner to create an installation DVD, go to the location where the ISO file is saved. Right-click the ISO file and select Properties. On the General tab, click Change and select Windows Explorer for the program you would like to use to open ISO files and select Apply. Then right-click the ISO file and select Burn disc image.

If you want to install Windows 10 directly from the ISO file without using a DVD or flash drive, you can do so by mounting the ISO file. This will perform an upgrade of your current operating system to Windows 10.

How to upgrade from the Windows 10 Insider Preview to Windows 10 RTM build

Technical Level : Basic

Summary
Microsoft announced on July 15th 2015 the Release To Manufacturing build for its next generation operating system, Windows 10. If you have been participating in the Windows 10 Insider Preview Program, you might be eligible for the final release. The following article will show you how to get it.
Details

IMPORTANT NOTE:

I just installed or reinstalled a preview build of Windows 10 and I want to upgrade to the final release, but it will not activate.

Microsoft has suspended Preview Builds and also deactivated their product keys at this time in preparation for the RTM release on July 29th. This means you won’t be able to download, install or activate builds 10162 and 10166 or earlier builds in order to qualify for the final release.

Your best option is to reinstall a valid license you have for either Windows 7, Windows 8.0 or Windows 8.1, make sure it is actvated, then upgrade from that to Windows 10 on July 29th or later.

If you have a preview copy of Windows 10 that was already installed and activated, then these procedures should work.

Click Start > Settings or press Windows key + i

Click Update & security

Click Windows Update

Click Check for updates

Wait while Windows 10 build 10240 downloads.

Wait while the installation prepares to install the Update.

When complete, follow the instructions to restart your computer.

Wait while Windows 10 is installed.

When setup is complete, sign in and complete the Out of Box Experience.

You can create a backup copy using the following instructions:

Leaving the Windows Insider Program — Switch to the Stable Channel

Even after Windows 10 is finalized for the general public, Microsoft will continue publishing revisions of Windows 10. Windows Insiders will have the option of getting these updates (automatically) unless they specify they no longer want it. These revisions will likely be unstable and unfinished. For most users unless you are an enthusiast, it is best you switch to the stable channel.

To do that, launch Settings (Start > Settings or Windows key + i)

Click Update and Security

Click Windows Update

Click Advanced Options

Under Get Insider builds click Stop Insider builds

You should now be running a stable final copy of Windows 10 RTM. Enjoy!

Important Notice regarding Windows Insider Preview Program eligibility for RTM build:

• Do you want to continue as a Windows Insider and keep getting preview builds after 7/29?
• Or do you want to upgrade your Genuine Windows 7 or Windows 8.1 system that has been getting Windows 10 Insider Preview builds to the 7/29 release and stop being an Insider?

“I want to continue as a Windows Insider!” If you want to continue as a Windows Insider past 7/29 there is nothing you need to do. You’re already opted in and receiving builds in the Fast or Slow ring depending upon your selection. This is prerelease software and is activated with a prerelease key. Each individual build will expire after a time, but you’ll continue to receive new builds so by the time an older prerelease build expires you’ll have received a new one. Since we’re continuing the Windows Insider Program you’ll be able to continue receiving builds and those builds will continue to be activated under the terms of the Windows Insider Program. We provide ISOs for these builds for recovery from any significant problems, but they are still pre-release software. As part of the program we’ll upgrade Insiders to what is for all intents and purposes the same build as what other customers will get on 7/29, but that will be just another build for Insiders, and those who stay in the program will simply get the next build after as well.

“I want to opt out of the Windows Insider Program on 7/29.” If you decide to opt-out of the program and upgrade to the 7/29 build you will be subject to exactly the same terms and conditions that govern the offer* that was extended to all Genuine Windows 7 and 8.1 customers. This is not a path to attain a license for Windows XP or Windows Vista systems. If your system upgraded from a Genuine Windows 7 or Windows 8.1 license it will remain activated, but if not, you will be required to roll back to your previous OS version or acquire a new Windows 10 license. If you do not roll back or acquire a new license the build will eventually expire.

Create bootable .ISO file using .ESD

Retrieve the .ESD file from the root of the drive in the C:\Recovery Image folder and create your own bootable copy which you can use for reinstallation purposes.

Download ESD Decrypter 4.7 ( esd-decrypter-wimlib-4.7z )

You can use NTLite as an alternative to convert the .ESD file into a .ISO:

Extract esd-decrypter-wimlib-4.7z to a folder.

Put the appropriate .ESD file you downloaded into that same folder.

Right click decrypt file in the same folder and click Run as administrator

Select option 1

When complete, burn to a blank DVD or create a bootable copy on a USB thumbdrive.

See article for instructions how to do that.

Preparing the .ISO file for installation.

See instructions for burning .ISO files in Windows 7 or later:

You can also use the Microsoft USB/DVD Tool, which is recommended for Windows XP users.

For UEFI based systems

If your computer is UEFI based, these are normally systems that come pre-loaded with Windows 8 or later, you will need to prepare the ISO file for such a configuration or you will receive an error message during setup. The thumbdrive needs to be formatted as FAT32 and use the GPT partitioning scheme. To do this, you need to use Rufus, a small tool you can download for free.

• Select ISO Image
• Point to the Windows 10 ISO file
• Check off Create a bootable disk using
• Select GPT partitioning for EUFI firmware as the Partition scheme
• Choose FAT32 NOT NTFS as the File system
