Block background activity of Store apps

Recommended

Microsoft Store apps do not run in the background until you open them. Regular programs are not affected.

Expected effect

Slightly fewer background processes and less network activity.

Possible side effects

Store apps (Mail, Calendar, Phone) will stop sending notifications while closed.

What exactly changes

Registry key	Value	Type	New value
`HKCU\Software\Microsoft\Windows\CurrentVersion\BackgroundAccessApplications`	`GlobalUserDisabled`	DWord	`1`

How to undo it

Before a change NyxBoost saves the previous values; "Revert" brings them back and removes those that did not exist before.

In NyxBoost: Recovery → “Revert” next to this setting's entry.
Without the program: open the Registry Editor (regedit), go to the key from the table and put back the previous value — NyxBoost records it in its change history.

How NyxBoost checks the result

After applying, NyxBoost reads the values again and compares them with the expected ones. To see the real effect on your PC, use FPS Lab: it measures the same game before and after.
