Before we go ahead, please understand that Insider builds may not be completely stable and have bugs. Installing it on your primary PC is not advisable. However, if you still want to install it, be prepared to meet crashes and instability.
Windows Insider Channel Limitations
When you are at Windows Insider Programme, the section will warn about any hardware limitations your PC may have for Windows 11. While it will allow you to join the insider program, you will not get access to few channels such as Dev, Beta. Microsoft restricts them mostly because the experience will be slower or degraded. The image below is from the Microsoft Blog.
It is also important to note that the PC will be marked if you roll back from the insider build to Windows 10. Microsoft will now give another exception and will now allow upgrading to Windows 11 Insider Preview builds again.
