requires little effort to use. If I knew of an easier way I would tell you. Its not the most reliable way, for that you need to have full control of the backups. It should be easy to turn it off. Just sign out using the OneDrive icon in system tray/taskbar area. Right click it choose settings, on account tab choose unlink this PC. You can also disable it from starting up with windows under settings-apps-startup.

It automatically backs up work onto the secure cloud drive so the files are available at the office as well as at home.

I shoot hundreds of photo raw files every day, and the network traffic to back them all up to OneDrive way exceeded my service plan. The ISP said reduce bandwidth or pay for a more expensive data plan. Instead, I disabled One Drive and built my own NAS. I back up all my photo directories on the NAS and also back up the final, focus stacked results on Dropbox. So one file sent to cloud backup for each image and hundreds stored locally. Actually, I save all the directories onto removable USB drives first, and the NAS copies them from there. All the USB drives are physically stored in a box after they're full, so the raid NAS is further backed up by the intermediate pass through drives.

In Win 10/11 but if not, it can be turned off. I can't remember if I got rid of it completely of just disabled and hid.

Call me old fashioned, but I want my files right here, on drives, in my house.
