Hi Pete,
For things like the narrator, you would want to look in the Control
Panel/Ease of Access center. For third party software you've installed, you
want to check within that program's options/preferences/settings to disable
it from loading as part of the startup group.
For things not quite so easy to discern, you can also use the system
configuration utility or windows defender to block them. This is usually a
last resort as it's better to disable them from within the programs own
controls rather than forcibly disable them.
