Windows 11 has initiated a default 'Efficiency' mode for all .exe tasks. This lowers the priority of the .exe in task managers and slows performance. When Closing ArcGIS Pro without a project this can result in ArcGIS Pro hanging for several minutes on Close. To avoid this recommend ESRI update the Target for the ArcGIS Pro shortcut as follows:
"C:\Program Files\ArcGIS\Pro\bin\ArcGISPro.exe" --disable-features=UseEcoQoSForBackgroundProcess
This same pattern appears to work for a shortcut for to ANY .exe (e.g., works for your Chrome and Edge shortcuts).
