After 10 years, support for Windows 7 ended on January 14, 2020.
In line with this, Microsoft will be stopping support for Power BI Desktop on Windows 7 on Jan 31st 2021.
After that, Power BI Desktop will only be supported on Windows 8 and newer versions.
The January 2021 release of Power BI Desktop Optimized for Report Server will be supported as per the Modern Lifecycle Policy i.e. supported until the next release (currently scheduled for May 2021), after which it will only receive security updates until January 2022, after which support will stop.
Microsoft is also making a change to the version of .NET that is required to run Power BI Desktop.
Starting from the October release you need the .NET 4.6.2 or greaterversion to be installed. This is installed by default with Windows 10 and for older versions of Windows the Power BI Desktop installer will launch the .NET installer for you.
