100% CPU usage on Windows 7 for R2022a
13 views (last 30 days)
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?

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.
