For a lot of my searches, I am just using an AI app so I never go to the website

On my Surface Pro I installed WSA (Windows Subsystem for Android) which emulates Android under Windows. Though I set it to run "Continous", after not using an Android app for a while WSA seems to shut down and needs to start again (that takes a long time) when using an Android app again.

Yesterday I googled for an hour to find the cause. No success. It was as if nobody else had that problem. Always only links to why Microsoft shuts down support for WSA, which is completely different.

Then I somehow had the idea to - for the first time - ask "Copilot", Microsoft´s AI. It presented me with 3 possible causes and one of it was it indeed (Though I set WSA to run "Continous" I nevertheless additionally had to set the Windows app setting "Run in Background" for the WSA process to "Always" (Default is "Energy optimized")).

Would have saved me this hour of googling, so I will use it more from now on --- and assume that's the thinking of everybody after trying such.
