Hello!
Making my first post from my shiny new Windows 10 machine

Seems like a BIG step up from XP. I've copied over most of my data and am working on getting everything up and running as close as I'd like it to be as possible.

With a new OS comes a new learning curve (for me) and I'm finding a few quirks(?) that I can't seem to figure out, that I knew exactly how to do what in XP.

Rather than making a new thread for every issue, I decided to do it all in one thread to remove clutter. Hoping someone has come across these issues before and can help me out (or at least point me in the right direction)...

Startup menu: How do I get things to load automatically at startup? On XP, I'd just drag the application to the Start folder on the menu in XP. 10 doesn't have anything like that. I've tried searching and found some way to enable a service and add it to lusrmgr.msc - but they don't startup automatically when 10 loads (even if I select "Start with Windows" from inside the app). Conversely, Spotify (which I loaded once) now loads automatically every time I start up, and I can't find a way to stop it from loading on boot. I also can't figure out how to stop Onedrive from loading at startup either.

Firefox applications/plugins: This may be more app specific, but how do I add the Firefox Classic theme? It doesn't seem to be available for 10 - or is it? I also can't find "Hide Tab bar with One Tab".

E-mail: What application do you use? I have MS Outlook 2016 on here (I have a couple of POP addresses), however the default Mail application looks horrible and completely non-customisable. Windows Live Mail doesn't seem to be available anymore. Any suggestions?

Malwarebytes: With the talk in the other thread of only needing one application (no AVG required), would I still need Malwarebytes?

WinRAR: is this needed in 10? Or does Winzip (which I think is on here by default) unpack everything?

Thanks in advance for the assistance
