Windows 10 is officially the most used operating system in the world. However, there are still people using Windows 7 or Windows 8.1 on their computers and devices. If you are one of them, you might want to upgrade to Windows 10, and get the latest and the greatest Microsoft has to offer. If you have a license key for Windows 10, you can upgrade right away, with the help of an app called Media Creation Tool developed by Microsoft. Here is how to use it to upgrade your Windows 7 or Windows 8.1 computer to Windows 10 today, for free:\r\n\r\n\r\nWhat you should know before you upgrade from Windows 7 or Windows 8.1 to Windows 10\r\nBefore you decide whether or not to upgrade to Windows 10, you should read the official Windows 10 specifications and make sure that your Windows 7 or Windows 8.1 computer meets the system requirements for Windows 10. Windows 10 demands the following:\r\n\r\n \tProcessor or SoC: 1 GHz or faster\r\n \tRAM: 1 GB for the 32-bit version or 2 GB for the 64-bit version\r\n \tFree hard disk space: 32 GB or larger\r\n \tGraphics card: DirectX 9 graphics device with WDDM 1.0 driver\r\n \tDisplay: with a minimum resolution of 800 x 600 pixels\r\n\r\nDuring the upgrade, Windows 10 might ask for your product key, so keep it handy. However, in our tests, if Windows 7 or Windows 8.1 is activated, you do not need to have a serial code (product key) for Windows 10. In this case, Microsoft updates Windows 7 or 8.1 to Windows 10 for free and activates your new digital license automatically.\r\n\r\nNote that you also need to have a working internet connection to download all the necessary installation data from Microsoft\u2019s servers and activate Windows 10.\r\nStep 1. Download and run the Media Creation Tool app\r\nThe first thing you have to do once you have decided to upgrade to Windows 10 is to download the software called Media Creation Tool. It is a small executable file developed by Microsoft that lets you download Windows 10 and create installation media or directly upgrade your current Windows 7 or Windows 8.1 computer to the latest version of Windows 10. As we found out, some people actually call it the \u201cupgrade Windows 7 to Windows 10 tool\u201d. :)\r\n\r\nTo get Media Creation Tool, launch any web browser and navigate this website: Download Windows 10. Scroll until you find the \u201cDownload tool now\u201d button and click or tap on it. It is located in the section that says: \u201cCreate Windows 10 installation media.\u201d\r\n\r\n\r\n\r\nDownload Media Creation Tool from Microsoft\r\n\r\nThen, you get to download the MediaCreationTool.exe executable file, with a size of 18.5 MB. Click\/tap on the Run button or save it somewhere on your PC, and then double-click or double-tap on it.\r\n\r\n\r\n\r\nChoosing to run the Media Creation Tool\r\n\r\nTo run the Media Creation Tool, you have to be logged in as an administrator on your Windows 7 or Windows 8.1 computer. When User Account Control (UAC) asks if you are sure that you want to run this app, click or tap Yes.\r\n\r\n\r\n\r\nConfirm that you want to run Media Creation Tool\r\nStep 2. Use the Media Creation Tool to download Windows 10 and customize the upgrade\r\nThe first thing that the Media Creation Tool asks you to do is accept the license terms. Read them carefully and, if you agree with them, click or tap Accept.\r\n\r\n\r\n\r\nLicense terms for Windows 10\r\n\r\nSelect the option that says \u201cUpgrade this PC now\u201d and then click or tap on Next.\r\n\r\n\r\n\r\nChoosing to Upgrade now\r\n\r\nNext, Media Creation Tool starts downloading the Windows 10 installation files. This step can take a while, depending on how fast your internet connection is.\r\n\r\n\r\n\r\nDownloading Windows 10\r\n\r\nNow, you have to wait for the Media Creation Tool to prepare the Windows 10 installation files. This step also takes quite a while, depending on how fast or slow your computer is.\r\n\r\n\r\n\r\nCreating Windows 10 media\r\n\r\nThen, Media Creation Tool checks for any available updates.\r\n\r\n\r\n\r\nMedia Creation Tool is Checking for updates\r\n\r\nOnce done, you have to agree to the license terms one more time.\r\n\r\n\r\n\r\nLicense terms for Windows 10\r\n\r\nAlthough kind of redundant, Media Creation Tool makes another check for updates. Wait for it to finish.\r\n\r\n\r\n\r\nMedia Creation Tool is Checking for updates\r\n\r\nOnce the updates check is over, you should see that the Media Creation Tool is \u201cReady to install\u201d Windows 10 on your PC.\r\n\r\n\r\n\r\nBy default, it chooses to keep your files and apps before upgrading to Windows 10. If you want that, click or tap on the Install button to continue. Otherwise, click or tap \u201cChange what to keep\u201d to personalize the upgrade.\r\n\r\n\r\n\r\nWindows 10 is ready to install\r\n\r\nIf you clicked or tapped on \u201cChange what to keep,\u201d there are several options you can choose from: \u201cKeep personal files and apps,\u201d \u201cKeep personal files only,\u201d or keep Nothing. Select the option you prefer and then click or tap on Next.\r\n\r\n\r\n\r\nChoosing what to keep when doing an upgrade from Windows 7 or 8.1 to Windows 10\r\n\r\nIn a deja-vu experience, the Media Creation Tool is \u201cChecking for updates\u201d once again, so wait for it to do its thing.\r\n\r\n\r\n\r\nMedia Creation Tool is Checking for updates\r\n\r\nThe Windows 10 installer now shows what you chose to keep on the previous step. Click or tap on Install to continue, or \u201cChange what to keep\u201d to make a new selection if you changed your mind. :)\r\n\r\n\r\n\r\nMedia Creation Tool is ready to install Windows 10\r\nStep 3. Upgrade from Windows 7 or Windows 8.1 to Windows 10\r\nThe Windows 10 installation begins, and you are informed that the process might take a while, and your computer or device might also restart a few times. This is a perfect time to have a coffee and get ready for Windows 10.\r\n\r\n\r\n\r\nInstalling Windows 10\r\n\r\nAfter the first restart, there are two paths on which the upgrade can go to:\r\n\r\n \tIf you chose not to keep your files and settings, follow the instructions from Step 4 in this guide;\r\n \tIf you chose to keep your files and settings, follow the instructions from Step 5 in this guide.\r\n\r\n\r\nStep 4. How to customize your Windows 10 installation if you don\u2019t keep your personal files and settings\r\nIf you decided not to keep your personal files and settings, the setup wizard starts installing Windows 10 as if it was a \u201cclean\u201d installation. You are shown an \u201cInstalling Windows\u201d message, and you can watch the installation\u2019s progress as you wait for the installation to be performed.\r\n\r\nThen, the final customization steps are the same as the ones we described in the last half of this tutorial: How to install Windows 10 from DVD, USB, or ISO file.\r\n\r\n\r\n\r\nInstalling Windows 10 when no files or settings are kept\r\nStep 5. How to customize your Windows 10 installation if you keep your personal files and settings\r\nIf you decided to keep your files and settings, after the first restart, you are shown a blue screen with the message \u201cWorking on updates\u201d and a percent number that shows you the progress. Wait for the upgrade to be performed, and don\u2019t shut down your computer. Several restarts are likely to be necessary, again.\r\n\r\n\r\n\r\nUpdating Windows 10 when files and\/or settings from Windows 7\/8.1 are kept\r\n\r\nOnce the upgrade from Windows 7 or 8.1 to Windows 10 is almost over, the installation process tells you that there are some updates available for your PC. Wait until the message goes away.\r\n\r\n\r\n\r\nWindows 10 has some updates to install\r\n\r\nThen, you can configure the privacy settings for your computer. Windows 10 asks if you agree to enable the use of your location, enable speech recognition, send diagnostics data to Microsoft, and let apps display relevant ads tailored to your behavior patterns. For each type of information, you can use the appropriate switch to set it. When you are done, press Accept.\r\n\r\n\r\n\r\nChoosing privacy settings for Windows 10\r\n\r\nWhen done, you are logged into Windows 10, and you can view your new desktop and a \u201cBrowse the web with Microsoft Edge\u201d notification.\r\n\r\n\r\n\r\nWindows 7 or 8.1 has been upgraded to Windows 10\r\n\r\nCongratulations, you have managed to upgrade from Windows 7 or 8.1 to Windows 10!\r\nDid you stumble upon issues while upgrading from Windows 7 or 8.1 to Windows 10?\r\n As you can see, upgrading from Windows 7 or Windows 8.1 to Windows 10 is not complicated.
