  • Windows11_Hardening

    A collection about Windows 11 security

    Project mention: How to prepare W11 from denied to collect any data from Microsoft? | | 2022-09-30

    checkout these two pages. there’s some other alternatives like SophiApp and Windows10Debloater, but i find following the microsoft documentation linked in the first two pages to be a lot more effective. since you’re doing everything yourself, you know exactly what is being changed and you won’t get any surprises if a feature you do like no longer works or works differently than expected. it isn’t too hard to do either, all of it is just registry keys you can copy and paste or group policy options
