Another thing to do, right click the cloud(the picture of one drive down by your clock), go to Settings, then Advanced, then towards the bottom (on the newest version anyway) it should say Download all files to this computer
it SYNCS files, it’s not a cloud backup, if you delete a local file it replicates that action in the cloud.
Dropbox is more prone to be used as a “stick a file here and i have an online backup of it” app. Onedrive automates this unless you delete that file locally.
(3 Years of 1 man IT department here, I’m a bit familiar with that PITA…but it’s saved butts at work because of it’s use during a failure)
Keep in mind that even though Microsoft wants you to upgrade versions, you do not HAVE to (in most cases). Oftentimes you can continue to use your computer for quite some time yet.
When you are told that an operating system (or product) is not supported, it just means that the company will no longer spend time fixing it. (If you break it, you own both halves) Of course, even this is not 100% correct.
I am still running a Windows 7 computer and still get some updates even though it has been out of ‘support’ for many years. My Windows 10 laptop also cannot be upgraded to Win 11 (not that I would ever do that, anyway).
