Windows 7 not genuine black screen
Windows will show “not genuine” messages if your copy of Windows isn’t properly activated. Product activation is necessary so that Microsoft knows that you obtained Windows legally and to limit the number of computers the same product key is used on. Show
Many other things beyond error messages might happen if you don't fix the "Windows is not genuine" problem. If your copy of Windows isn’t activated, your computer might log you out every hour, reboot occasionally, give you a permanent black desktop, or even prevent you from installing some Windows updates. What the Error Looks LikeThe error is different depending on the Windows version. For example, when Windows 7 Build 7601 isn’t genuine, you’ll see this error:
You’ll probably also get occasional pop-ups or see messages in other parts of Windows. Here are some examples:
Why You’re Seeing This ErrorThe most likely reason for an error like “This copy of Windows is not genuine” is because it’s legitimately not genuine! This will happen if you’ve installed Windows without a valid product key, and now the operating system, probably after a Windows Update, is letting you know. A less common reason for these activation errors is if malware has attacked your computer so that the valid activation files you had before the infection are now corrupted or missing. Windows can’t verify the authenticity of your copy of Windows. How to Fix ‘Windows Is Not Genuine’You can try several things to fix the “Windows is not genuine” message, but which one is best to try depends on your situation and what you see, so read through the various tactics below before getting started. Enter a Valid Product KeyIf this is your first time using your computer since you installed Windows, but you haven’t yet entered the product key, the best way to stop this error is to enter your product key to activate Windows. You can change your Windows product key through Settings in Windows 11, or Control Panel in Windows 10, 8, 7, and Vista. Changing the Windows XP product key is done through the registry. Another way to enter a different product key in Windows is through the Run dialog box. Open it with WIN+R and then enter the following:
You'll get a prompt where you can type the product key. Reset the License InformationThis fix for “Windows is not genuine” errors resets the information used to activate Windows. If the information is valid but somehow corrupted, this should remove the error.
Disable the Plug and Play PolicyThis method only applies to some versions of Windows. You might be able to fix the “not genuine” error by disabling the Plug and Play Group Policy object. This might be the case if the Network Service account doesn’t have the proper permissions to access the HKU\S-1-5-20 registry key.
Apply the Proper Registry PermissionsIf the above steps didn’t work to fix the error about Windows not being genuine, or you couldn’t complete them because of what you found during Step 4, you can try adjusting the permissions Network Service has to access a specific registry key.
Delete the KB971033 UpdateThis method applies to Windows 7 only. If Windows 7 won’t activate properly, there might be an issue with an update installed via Windows Update, specifically, one for Windows Activation Technologies (KB971033). If you know that your product key is genuine, removing and reinstalling this update could solve this problem.
It’d be a good idea to now check for updates again with Windows Update and then install any available ones, like a fresh version of this KB971033 update. It might not make sense to reinstall the same update that caused the error in the first place, but the update could have been installed incorrectly; trying again will allow the update another chance at installing properly. Check Your Computer for MalwareA virus is an unlikely reason for a “Windows is not genuine” message, but you can’t rule it out without checking. You can use plenty of programs to check for various types of malware, including on-demand scanners, spyware cleaners, and full antivirus software programs. Another option is a bootable antivirus tool. These are useful if you can’t even boot into Windows to run a scan because they work before Windows starts. You’ll need a flash drive or disc to use a bootable malware cleaner. Reinstall WindowsOf course, deleting Windows from your computer and reinstalling it is the most drastic solution to a "Windows is not genuine" error. However, if you've tried all of the above and Windows still won't properly activate, you're left with starting from scratch. Before installing Windows over your current version, make sure to have a copy of your Windows product key to avoid having to buy a brand new copy.
