Well, fuck. Windows finally released 24H2 despite all the controversy about Windows Recall.
If you have Windows 11, to see if you have it, go to
Settings >> Windows Update >> Update history
Look for an entry titled "Windows 11, version 24H2"
If you have it and want to see if it is enabled, start CMD as administrator and type in
DISM /online /Get-FeatureInfo /FeatureName:Recall
Theoretically, this should not be enabled by default except on CoPilot-branded computers, but who trusts MS?
