When upgrading to Windows 11 from Windows 10 or when installing an update to Windows 11, some features may be deprecated or removed. Here are the known issues in the first Windows 11 Insider Preview Build And unlike the leaked build, the Insider Preview version allows you to personalize the operating system without validating your license, even though the Settings app tells you need to activate Windows. Windows 11 is fast, you will notice the difference in performance, it's unmistakable. The version number of the build is Windows 11 Insider Preview 0.51 (co_release).
So, I installed the latest Windows 10 Insider Preview, and followed the steps that I mentioned above, to get the Windows 11 Insider Preview. I was using the leaked version of the operating system for about 10 days, and could not get the Dev Preview update to show up when I tried to. The installation was slow, it took about 30 mins, but that could be because I was installing it in my virtual machine. I was expecting it to prompt a restart, but to my surprise, Windows 11 was being installed in the background. The Windows 11 Insider Preview should start downloading, wait for it to complete. Now, go to the Windows Update section in the Settings App, and click the Check For Updates button. Existing Insider Preview users can continue on the Dev channel. Since Microsoft has only released Windows 11 to the Dev Channel, you have to set it as your preferred channel. Sign in to your account using the "Become an Insider" option, or if you're already signed in, choose the Insider Account. Select the Windows Insider Program at the bottom of the sidebar.
If your PC meets the Windows 11 minimum system requirements, open the Settings app, and navigate to Windows Update. Microsoft won't explain why your system may not be compatible with the new OS, but there are a couple of new tools that tell you what the issue is.
If you aren't certain about it, check the PC Health Check app to verify your computer's compatibility. Make sure the system is capable of running the next-gen OS. To enroll in the Windows 11 Insider Preview Program, you need to have Windows 10 installed on your computer, in other words, PCs running on Windows 7 or 8 aren't going to make the cut here.
