For this old timer, my Christmas present of a MacBook Pro is giving me a headache, stressing me out. [View all]

I just talked to my computer guru about my situation. He is not making house calls now and suggested that I keep using my desktop(Win10) and laptop(Win7). He has done all the service I have needed for years and advised me that the change from a PC to a Mac is probably a little too much for me. He and I both know my limitations.

My Problem: I want to post things on Facebook using my old digital camera. I am moving and want to sell some good stuff. I have a desktop that works fine but I can't use the digital camera with it. Cannot find the installation disk for that camera. My old laptop has a dead battery. I can get a new battery but the laptop is still Win7. If I plug it in, all is fine. I asked if I could still use it to post to Facebook and was told that it was OK. I would not use the laptop for anything else.

I know some of you still use Win7. Do you feel comfortable posting on Facebook with Win 7? I can plug in the computer and perhaps shortly buy a new battery. My concern is using 7.
Do you who still use Win7 feel this is OK? I can get a battery cheaply by way of a suggestion from A DU member. I just don't want to make myself vulnerable to some awful event.

My wonderful family thinks they did me a favor since I have an iPhone and thought this would be easier for me.
Yikes. At my age, this change is too much without help that I cannot get at the moment.
I would appreciate any advice from Win7 users.

Thank you for any advice. I've tried the Apple tutorials but am still lost. Don't laugh, I'm 78 years old!
