There are times when you see a message in Windows Defender saying, “The Threat Services has stopped, Restart it now” when you try to use it. This kind of error is usually fixed by simply clicking on the Restart now button.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager
• After opening the Services Manager, look for the following services and make sure that their Startup type is set to their default values:
  • Windows Defender Advanced Threat Protection Service – Manual
  • Windows Defender Antivirus Network Inspection Service – Manual
  • Windows Defender Antivirus Service – Manual
  • Windows Defender Firewall Service – Automatic
• You can right-click on each one of the listed services and then select Start to start them.
• And if some of the services don’t have their default values, just double-click on the Services to change the Startup types and select the correct option from the drop-down menu of the Startup type under the Properties box.
• Next, set up the Startup type of these services to Automatic and then click on the Start button if the services are not running yet.
• Now click on the Apply and OK buttons to save the changes made and then see if it fixed the problem or not.

Option 2 – Try modifying some entries in the Windows Registry

If the first option didn’t work in fixing the problem, you can try to alter some entries in the Windows Registry using the Registry Editor.

• First, tap Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKLMSoftwarePoliciesMicrosoftWindows Defender
• From there, look for the “DisabledAntivirus” and “DisableAntiSpyware” DWORDS from the right pane and change each one of their values to “0”. On the other hand, if you don’t see any of these DWORDS, you can create them instead and give each one of them a 0 value.
• To create a DWORD, simply right-click on any empty space and select New > DWORD. Then name them both as “DisabledAntivirus” and “DisableAntiSpyware”.
• Afterward, set the value of the newly-created DWORDS to 0.
• Now exit the Registry Editor and reboot your PC to apply the changes made and then check if it has fixed the error in Windows Defender or not.

New Apple's upscaling technology called MetalFX will place iOS and macOS devices back into the gaming world. Apple had great games back in the old days and some all-time hits like the prince of Persia have been made first for apple but along the way, it just lost it.

Same as NVIDIA's DLSS and Intel's XeSS systems, Apple MetalFX also uses AI algorithms to upscale the resolution of output game frames. So, for example, the GPU inside your MAC might render the game at 1080p, but through MetalFX and AI upscaling it will look like a 4K image but have a good frame rate since it is rendered in base resolution.

The ability to make AI strike a good balance between performance and image quality is a key to technology in today's modern gaming and having this technology will help developers a ton to be able to achieve great results on Apple hardware.

The First MetalFX Games

So far three official games that will use this technology and be released natively for Appl hardware are Resident Evil 8 Village, GRID legends, and No Man's Sky. All three games have been confirmed and Resident Evil 8 Village is already sent for review people are impressed since the game can run smoothly on all Apple devices, even ones with an M1 CPU.

Apple is back into gaming

When you say Apple gaming is probably the last thing that comes to your mind but truth be told Apple makes more money from games than Microsoft, Nintendo and Sony combined. Also, Apple itself was a big player once regarding computer games as well, Myst and Prince of Persia are games that were made and have been released for Apple first. Bungie was also founded by Apple developers and Halo was originally announced as a Mac game.

Apple has been trying and pushing gaming on its platform since it kind of died down. Today all Sony, Nintendo, and Microsoft controllers work without any issues with all Apple products. Apple also has its own gaming subscription service, Apple Arcade, and its Apple TV is packed with GPU that can rival Xbox ones.

MetalFX API ties and brings it all together, it is designed to get the most performance from the hardware by minimizing overhead.

Now, computers and laptops do not hold any large numbers if we look at the user base, and that could deter developers but if we look at iPad and iPhone things are different there, much different. How same CPU power these devices and how MetalFX is available across all products it is clear that there is a market for games there. No Man's Sky is coming to iPad using these technologies and bringing full computer experience to tablets.

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.
