Windows 10: One drive questions never used it

Hi, I never used MS OneDrive at all and never made an effort to register to it. However, it has been visible in my PC since January-2020. I do not recall what happened back then to make it appear. I have been using Win-10 for at least 5 years.So now I am thinking of using it but I have a few questions.1 If I never registered for it, why is it there?2 Can I password protect access to it?3 how can I find out how much available space I have in it?4 I am able to access all the files in it, except for the PDF file that is giving me an error. Why?

:)

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Optical Drive Issue

Hi Jerry, you're welcome.

Here's mine after I rt clk'd on my Documents Folder like you show in Scrsht 11:




I'd like to wait until you reply to my question in Scrsht 12, if it is a remnant of the process try deleting the one on the dsktp and see if the one in send to also disappears. If it stays in send to, test it, and if you're still having problems I'd suggest you could go back to: Option One: To Add or Remove Items in Send To context menu for Your Account (current user) and do Step 3 to remove it and start over using Step 4 but be very careful of your steps in creating the shortcut and be sure you d&d that shortcut to the send to part of the address.

I'm busy today and I probably won't be back until the evening.
