Microsoft’s initial Windows 11 hardware requirements were not really well received by users and they were not really clearly represented from the start making a lot of potential customers slowly drift away from the hype. It seems that Microsoft has acknowledged this since they have changed their tune about system hardware requirements for the upcoming Windows 11. It seems that Windows 11 will be able to be officially installed on unsupported computers but with a little inconvenience.

What is a catch?

Windows 11 will still have the same hardware requirements and if the PC meets them, that computer will be officially supported, other ones (any that can run Windows 10) that do not meet system requirements can still run Windows 11 but the system will have to be clean installed. So no upgrade option for old computer users, just a clean install. This means of course that you will need to download the ISO image and make a bootable USB in order to install it. Also since you will be doing a clean install do a backup of the hard drive since it will need to be formatted. Also, Microsoft has stated that with unofficially supported PC some driver updates might not be delivered leaving you with either older driver versions or relying on your hardware manufacturer on them. This is still not confirmed by Microsoft, just stated as an option. We will see how it goes.

Conclusion

It is very good that Microsoft has reconsidered its system requirements and will not stubbornly push its initiatives over the top requirements allowing even older computers to install new OS. I am sure over time lot of users will upgrade their hardware and drive into officially supported waters, but it is good that they will be able to use new OS on their current hardware.

In case you don’t know, Windows 10 comes with a native ability to project to another screen, be it wireless or wired.

If you do have a third-party program installed, try uninstalling it then manually starting Windows Defender.

Method 2:

If method one does not work, you may be infected by malware or a virus that has tampered with the settings on your computer and will not allow Windows Defender to start automatically or manually.

First, open Run by holding the “Win” key and pressing the “R” key. Then type “Regedit”. The program will ask for permission to follow through with this action. Click on “Yes” and the Open Registry Editor will open.

Find the HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionImage File Execution Option and check to see if there are any files similar to MSASCui.exe or MpCmdRun.exe. If there are any file entries that resemble that, you will want to right-click on them before selecting the “Delete” option. If you do not see any entries that match, this is not the issue with your Windows Defender and you will want to try another method.

The Registry on your computer is very important. It helps tell your computer what programs are safe to run, what programs should be run, and what programs should not be run. If it is tampered with by a virus or Malware, multiple system operations can be affected.

However, if you did find similar file names, and you deleted them, try to start Windows Defender manually. If it does not work again, move on to the next method. 

Method 3:

If the first two methods do not work for your issue, and you are still receiving error code 0x80073afc when attempting to start Windows Defender, this step should solve the problem if you have Restore Point installed on your computer, which you most likely do.

For this method, we will be restoring your computer to a previous Restore Point. First, just like in method two, hold the “Win” key and press the “R” key. This will open run. Next type “Rstrui.exe” and click “ok”. After some time, you will see System Restore Windows. Click “Next” and select the restore point that you would like to go back to. After your computer has restored to the point you selected, check to ensure that Windows Defender has started correctly.

If the above methods aren't able to rectify the issue, you might have to download and install a powerful automated tool to get the job done.
