Word 2007 docs in read-only mode

I recently upgraded from Windows 7 to Windows 10. Unknown to me until just the other day, my documents are in read-only mode. I can edit one, create one, and print one, but I can't save any of them. An error pops up saying I don't have permission to save in this location. Contact the administrator to obtain permission! I am the administrator. I researched this problem on line, and I think I inadvertently followed instructions found to solve this with Outlook. I don't even have Outlook. Nonetheless, I followed the instructions and the doc problem is solved. BUT, I lost access to Microsoft Edge. I can't get online with Edge. I didn't care for it anyway, so I'm using Chrome now. Should I reverse what I did, assuming there is another solution to fix the Word problem?
