I don’t think you can opt out since they anticipated that people would want to after the big backlash and integrated into the OS so it was essential and couldn’t be. No reason for that if it’s truly a nice tool for the users , the only reason for that is it’s a nice too for microsoft to get the users data.
You can enable or disable.
Enable Recall
If the system hasn't already prompted you to enable the feature, you can use these instructions to opt into the Windows Recall:
- Open Settings[Windows key + i key].
- Click on Privacy & security.
- Click the Recall & snapshots page on the right side.
The "Filter lists" settings allow you to prevent the Recall feature from saving sensitive information. By default, the feature can filter passwords, credit cards, and more. However, you can also exclude apps and websites.

In any case, I recommend using Autoruns
This utility, which has the most comprehensive knowledge of auto-starting locations of any startup monitor, shows you what programs are configured to run during system bootup or login, and when you start various built-in Windows applications like Internet Explorer, Explorer and media players. These programs and drivers include ones in your startup folder, Run, RunOnce, and other Registry keys. Autoruns reports Explorer shell extensions, toolbars, browser helper objects, Winlogon notifications, auto-start services, and much more. Autoruns goes way beyond other autostart utilities.
Autoruns' Hide Signed Microsoft Entries option helps you to zoom in on third-party auto-starting images that have been added to your system and it has support for looking at the auto-starting images configured for other accounts configured on a system. Also included in the download package is a command-line equivalent that can output in CSV format, Autorunsc.
You'll probably be surprised at how many executables are launched automatically!
I store my files in folders where I know where they are. I do not need a 3rd party program to record what I am doing.
