I have a MATLAB R2022a version installed in Windows 7 64-bit Operating system. It has a network licence activated on a local network (not connected to the internet).
When I start the Matlab and click in “Help Documentation” the CPU usage becomes 100% and the Matlab freezes. I am unable to do anything more. My system has 8 GB RAM running on an Intel ® Core™2 Quad CPU Q9650 @3 GHz processor
Following previous suggestions on Matlab Answers I have allowed Matlab R2022a to be “Allowed” through the Windows Firewall.
This decreased CPU usage marginally, but it reverts back to 100% usage on something simple like clicking on help Documentation.
I have not even loaded any data or programs so far.
How to run Matlab R2022a in my PC in a normal way without the software consuming too much resources like this?

Experiment with
com.mathworks.mlwidgets.html.HtmlComponentFactory.setDefaultType('HTMLRENDERER');
which should change how the documentation is rendered.

com.mathworks.mlwidgets.html.HtmlComponentFactory.setDefaultType('HTMLRENDERER');
This is not having any effect on the problem.
Is Matlab R2022a compatible with older generation CPU's or is there a bug which can be fixed?
My PC can run RAM intensive and CPU intensive applications like rendering from a video creation software, but even basic run of Matlab command prompt takes up 100% of CPU and I have to force shut down Matlab through the task manager.

The System Requirements page lists the supported Windows operating systems for release R2022a as Windows 11, Windows 10 (version 1909 and higher), and Windows Server 2019. Windows 7 and Windows Server 2016 are explicitly listed as no longer supported.
In addition, Microsoft ended support for Windows 7 in January 2020. Their recommendation is to update to Windows 11.

I happened to notice yesterday that Windows 11 not only requires TPM2.0, but also requires 7th generation Intel or later.

Thanks for the response.
If there is anyway in which I can run Matlab 2022a on Windows 7 PC kindly let me know in this thread. I am not keen to upgrade to Windows 10 as my PC (CPU) is old.
