Noticed, that despite disabling auto updating appx in settings of Microsoft Store, Windows still auto updating in background appx such as: Phone Link, Mixed Reality Portal, etc. which is labeled as "System Components". Other Windows appx like Calc, Photos doesn't auto updating. Is there are way to turn off updating these "System Components"? OS is Windows 10 Pro. Background apps all turned off, check for system updates is automatic.
You can block WU updates for Removable Apps. System Components are updated whenever they're included inside the Monthly LCU.
