Page 1 of Strange stuff appearing on my PC

Sometime back, probably as a result of one of those annoying blue screen windows updates, One Drive appeared or came into use on the PC.
I never use it or look at it so just ignored it and filed it as one of those I'll deal with it later problems.
Pootling around last night looking for something I go through the list of folders and in 'videos' is loads of backed up clips with JPG attached which appear to be from someone's phone but nobody in the family or that I even recognise.
Some look personal some just stuff looked at or gifs sent and received.

I've uninstalled One Drive and deleted everything on it, or rather it's sitting in the recycle bin awaiting the final sanction in case I need it for further investigation. All 110GB of it.

No Malware problems, anti virus keeps reporting nothing detected.
Just wondering if anyone has any idea How the **** it got there and where from.
Also anything I should check or do other than what I've already done.

EDIT: Just thought if it's on One Drive then it's not actually on my PC is it, just in the cloud. So has some random person been innocently backing up and it's in my stuff rather than his own? ie: a Microsoft problem

Very strange.
What is in the One Drive folder in your profile - c:\users\<snaps!>OneDrive ?
Where is the video folder you mention - in your main profile or within the OneDrive folder?  If it's in your actual videos folder that's even strangererer.
Also, it's not quite true to say it's all Cloud and not local - it depends how it's configured - i.e. could be local and backed up to the Cloud etc.

Difficult to say what was in the whole One Drive or the set up as minor panic mode set in with the whole uninstall/delete thing.
It was definitely in the One Drive video folder though not in the PC main drive.
I do pay Back Blaze as a regular back up service (thanks RJS) so I suppose I could go back before I deleted everything but I'm loathe to do that.

I did notice that my main screen has a lot of icons missing which is probably all shortcuts to files for family stuff. The stuff will still be there just not the shortcuts.

This sure is strange and scary.

Onedrive uses your Microsoft account, so make sure it's your Microsoft account! Also roll the password on it. By all means write down the password, but make sure it's not in any password leaks or is easy to guess.

Windows 10 and 11 also use the Microsoft account to log in.

Is there any possibility an old PC or phone of yours could have had your account logged in? Also you could use an exif tool to see if there is any information on where the photos were taken. If they were shot with a phone then it may be adding GPS locations to each one.

I did have a phone nicked a couple of years ago but I got the IMEI switched off and it was finger print and passcode locked when it went.
Not worth more than about 50 quid on the legal market at the time so I don't see it being worth anyone's effort to un lock it.
Nothing else has ever surfaced from it so not sure that would be it.

Just changed the Microsoft password which must have been the same just about forever as I never use anything that needs signing in to.
Used a randomly generated one.

Further info.
All images say they were generated on 5th March 2018 but all were uploaded to One Drive on 23rd August 2021 in a two minute timespan.

EDIT: Ran a Malware scan and a deep virus scan both found nothing.
