Cannot edit photos any more

The pictures I have had for years I cannot edit. I can save them to my desktop and the computer does not argue with that. I had the pictures on Windows 7 and now I have 10 and these photos cannot be edited at all. The message is this when I try to do any kind of edit. "This .jpg already exists and is read only. You can save the file with another name or to another location"
Anyhow when I right clicked on the jpeg it does not have a checkmark in the Read only box but Windows says it is read only. Never had any issues with these .jpgs before. I was getting the same message with some .docs that were created in Word as well. If I hit Don't save then the no editing has happened and the photo closes. I am opening them with Microsoft Office 2010 Picture Manager.

Don't know why this is happening.

Note: I just opened this one jpeg in Paint and added a caption and it did save that. I then opened it in Microsoft Office 2010 Picture Manager and did a simple crop to see if I could save it and got the same stupid error message. So I had to hit Don't Save again. But whatever I did in Paint it was on the image though.

Create a folder called C:\TEMP and copy a file or two there and test..

Windows can get overprotective when it thinks ownership of the file is in question... The Desktop and My Docs folder can cause the error...

I added OIS.exe to Windows Security>>Ransomeware Protection>>Mananage Ransomeware Protection >> Allow an app through Controlled folder access to this list and then I was able to edit and save my pictures that I was having a problem with. Same with some Word documents. I had to add chkdsk there as well because my Windows 10 would not let me check external hard drives for errors. Now these problems have so far disappeared.
