I wonder how much performance will be used to run all the advanced Microsoft telemetry software (which collects & reports user data for Microsoft and which can't be disabled) and all that ad software they force on users. I still wonder how it is legal to use Microsoft software in the EU in government surroundings. The German authorities publish tons of papers on how to use Windows&related ( https://www.bsi.bund.de/SiteGlobals/Forms/Suche/EN/Servicesuche_Formular.html?nn=907774&resourceId=149134&input_=907774&pageLocale=en&templateQueryString=windows&submit.x=0&submit.y=0 https://www.bsi.bund.de/SiteGlobals/Forms/Suche/EN/Servicesu... ) , instead of simply disallowing to use Microsoft software. With the data collection for "AI" it only gets worse.
