How do you tell which Windows you have? The answer to this question is not rocket science. It is not even a complicated thing to do. However, it is a question you may have to answer so that you receive technical support with a problem you have. If you have handled Windows devices before, the answer is only a couple of clicks away. On the other hand, if you are like our parents, you may call your children or friends at 8 AM to ask them how to do it. This tutorial is mainly for everyone who wants to save the cost of a call and find out what version of Windows they have on their own. Let\u2019s get started:\r\n\r\n\r\n\r\nIMPORTANT: If you already know that you have Windows 10 and you want to find out exactly what edition and type, read how to check the Windows 10 version, OS build, edition, or type. Also, here\u2019s how to validate whether Windows is activated and genuine.\r\n1. How to tell what version of Windows you have just by looking at the sign-in screen\r\nIt may sound too easy to be true, but it is often enough to look at the Windows sign-in screen and find out whether your Windows is version 10, 7, or 8.1. Start your computer or device and wait for it to boot. When the sign-in screen shows up, check the way it looks.\r\n\r\nIf the sign-in screen on your PC looks similar to the screenshot below, then you are using Windows 10:\r\n\r\n\r\n\r\nWindows 10 sign-in screen\r\n\r\nIf what you see when you sign in looks like the screenshot below, then you are using Windows 7. This version of Windows is all about lively blue colors. :)\r\n\r\n\r\n\r\nWindows 7 sign-in screen\r\n\r\nNOTE: Windows 7 also tells you its name and edition at the bottom of the sign-in screen. For instance, the Windows 7 edition in the screenshot above is the Ultimate one.\r\n\r\nAnd if your sign-in screen looks like the one below, then you are using Windows 8.1. It looks boring, doesn\u2019t it? :)\r\n\r\n\r\n\r\nWindows 8.1 sign-in screen\r\n2. How to check what Windows you have by pressing the Windows key\r\nWindows 10, Windows 7, and Windows 8.1 differ quite a lot in what their user interface looks like. Just by looking at your desktop, taskbar, icons, Start Menu, or Start screen, you can immediately tell which Windows you have.\r\n\r\n\r\n\r\nIf you have Windows 10, then your desktop and icons have a flat design, your taskbar has a search field or at least a search button on it. Press the Windows key, and the Start Menu shows up. If it has tiles on it, like in the screenshot below, then you are using Windows 10.\r\n\r\n\r\n\r\nWindows 10 desktop and Start Menu\r\n\r\nWhen you press the Windows key, if your Start Menu is transparent and has a search field inside, and the edges of the taskbar and icons are rounded, then you are using Windows 7.\r\n\r\n\r\n\r\nWindows 7 desktop and Start Menu\r\n\r\nIf you have a Start button on the bottom-left corner of your screen, but it does not open a Start Menu but a Start screen filled with tiles, then you are using Windows 8.1.\r\n\r\n\r\n\r\nWindows 8.1 desktop and Start Screen\r\n3. How to tell what Windows you have by locking your PC\r\nYou can also tell what version of Windows you have just by checking how the lock screen looks. The fastest way to lock your PC is to simultaneously press the Windows + L keys on your keyboard. If you are using a Windows tablet, you can also press the Power button twice to do the same.\r\n\r\nIf the lock screen looks similar to the one in the screenshot below, with a beautiful wallpaper image, and the icons for network and battery on the bottom-right side, then you are probably using Windows 10.\r\n\r\n\r\n\r\nWindows 10 lock screen\r\n\r\nIf the lock screen looks like the one below, it is evident that you are using Windows 7. Windows 7 even tells you what edition you have on the bottom of the screen.\r\n\r\n\r\n\r\nWindows 7 lock screen\r\n\r\nIf your lock screen looks similar to the one below and the network and battery icons are shown on the bottom-left corner, then you are using Windows 8.1.\r\n\r\n\r\n\r\nWindows 8.1 lock screen\r\n4. How to check what Windows version you have by running the winver command\r\nTo find which Windows edition you have, you can also use the winver command. There are several ways in which you can run this command:\r\n\r\n\r\n\r\nPress the Windows + R keyboard keys to launch the Run window, type winver, and press Enter.\r\n\r\n\r\n\r\nwinver command in Run\r\n\r\nOpen Command Prompt (CMD) or PowerShell, type winver, and press Enter.\r\n\r\n\r\n\r\nwinver command in PowerShell\r\n\r\nYou can also use the search feature to open winver.\r\n\r\n\r\n\r\nwinver command in Search\r\n\r\nRegardless of how you choose to run the winver command, it opens a window called About Windows. This shows you the operating system that you\u2019re using, Microsoft\\'s internal version of the operating system, and the Windows edition that you own.\r\n\r\n\r\n\r\nwinver command: About Windows\r\n5. How to find the Windows you have from the System page\r\nAll the specifications of the operating system that you are using are located on the System page. There are several ways to get there. The fastest way to get to the System window is to press the Windows + Pause\/Break keys on your keyboard.\r\n\r\n\r\n\r\nWin + Pause (Break)\r\n\r\nIf you\u2019re using Windows 10, this brings up the Settings app and takes you to the System page. There, you can see details about your PC, including Windows specifications.\r\n\r\n\r\n\r\nWindows specifications in the Settings app\r\n\r\nIf you\u2019re using a different Windows version, like Windows 7 or 8.1, the Win + Pause keyboard shortcut brings up the System window from the Control Panel. Except for a few minor visual differences, the System window is identical and displays the same information, regardless of what Windows you have.\r\n\r\nIn the Windows edition section from the top of the window, you get to see what Windows version and edition you are using.\r\n\r\n\r\n\r\nWindows information in the Control Panel\r\n6. How to tell what Windows you have using the System Information app\r\nThe System Information app offers another easy way to find out what Windows you have. Open it and check the first line from the System Summary: it should tell you the name of the Windows operating system you use.\r\n\r\n\r\n\r\nOS Name in System Information\r\n\r\nThe System Information tool offers a lot of details about the system, not just the name of the OS. If you want to learn more about it, read: How to see details about your PC\u2019s hardware and software, using System Information.\r\n7. How to tell what Windows you have using DirectX\r\nAnother tool that\u2019s surprisingly useful if you want to find out what Windows you have is Microsoft\u2019s DirectX Diagnostic Tool. Open it either by using the search or by running the dxdiag command in CMD or Run (Win + R). After it opens, check the System Information area from the System tab - it tells you what Windows you have, including its edition and build number.\r\n\r\n\r\n\r\nOperating System information in DirectX Diagnostic Tool\r\n8. How to check your Windows version in cmd (Command Prompt)\r\nAnother simple yet non-intuitive method of finding out what Windows you have is offered by Command Prompt, and it doesn\u2019t even require you to run a command - you just have to open it. Before anything else, Command Prompt tells you the version of Windows you use. If it shows Version 10, then you have Windows 10.\r\n\r\n\r\n\r\nWindows 10 is shown as Version 10 in Command Prompt\r\n\r\nIf you see cmd display Version 6.1, then you have Windows 7.\r\n\r\n\r\n\r\nWindows 7 is shown as Version 6.1 in Command Prompt\r\n\r\nIf Command Prompt shows Version 6.3, then you\u2019re using Windows 8.1. If it shows Version 6.2, you\u2019re using Windows 8.\r\n\r\n\r\n\r\nWindows 8.1 is shown as Version 6.3 in Command Prompt\r\n9. How to find what Windows you use with the systeminfo command (in Powershell or Command Prompt)\r\nOne other way to check the Windows version in cmd is to take advantage of the systeminfo command. Although you could just run this command and look for the information you want, it would be easier to pipeline all that data to a search for the term \u201cOS,\u201d like this: systeminfo | findstr OS. That gives you only a few lines of data, and the first one tells you what Windows you have.\r\n\r\n\r\n\r\nsysteminfo | findstr OS\r\n10. How to tell what Windows you have using Registry Editor\r\nIf none of the previous methods suits you, you might prefer using Registry Editor to find out what version of Windows you have. Open Registry Editor and follow this path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersion. Then, on the right side of the window, the ProductName key tells you what Windows you use.\r\n\r\n\r\n\r\nHow to tell what Windows you have: ProductName in Windows Registry\r\n11. How to tell what version of Windows is installed on a hard drive without booting it?\r\nWhat if you have a hard drive on which there was a Windows operating system installed, but you don\u2019t know what version? What if it can\u2019t boot, but you need to know what Windows is on it. The easiest way to find out is to check the license.rtf file from the \u201cWindows -> System32\u201d folder.\r\n\r\n\r\n\r\nlicense.rtf in Windows -> System32\r\n\r\nOpen it using WordPad or any other text editor you prefer. With the sole exception of Windows 10, license.rtf should tell you what Windows you have on its first page. In the screenshot below, you can see what it looks like if you\u2019re using Windows 7.\r\n\r\n\r\n\r\nlicense.rtf showing that you have Windows 7\r\n\r\nIf you\u2019re using Windows 10, the license.rtf file doesn\u2019t specify the Windows version you have. This lack of information is actually useful information: if it doesn\u2019t say anything about the Windows version, you use Windows 10! :) If you think about it, it kind of makes sense, as Windows 10 is the last Windows Microsoft will ever make, so the license terms apply forever and only get updated from time to time.\r\n\r\n\r\n\r\nlicense.rtf showing that you have Windows 10\r\nWhat Windows do you have?\r\n Now you know quite a few different ways to find out what version of Windows you are using.
