" Make at least one other account with administrator rights and use that for changes in your system. "
Without a spare admin account, the issue of corrupt profiles could mean that you get to reload the OS when having a spare would have made a fix trivial.
Also, I rarely enable the Guest account. In fact I only do to test out issues with that account. Why use that and not a new account?
I'll try and keep this as short and concise: I've got Windows 8 on a new Toshiba Satellite S855. I didn't create a guest acct. after I got it back in March - as I remember, it seems like I had some issues creating it because of the stupid Msoft forcing me to join/create and acct. for their new setup or something. Anyways, so I just skipped it and been using the desktop on my admin acct. to do all my net browsing, email, etc. I put my wimpy little music collection and some movies on it from my last lapT, and then last week I bought and downloaded Elder Scrolls V: Skyrim from Gamestop/Bethesda/Steam and installed it. I've been playing catch up reading up on all the different things to do to make a more secure computer other than just letting MS essentials or AVG (on my last lapT) alone to do the work. I've got CCleaner and Malwarebytes on all the computers in the house and running MS essentials on my 8 & my old vista as well as my roomies running 7, but I'm not sure what all else I should install. Mainly though, I just want to know how to transfer things (For Dummies as I'm totally not very tech savvy) from an Admin acct. over to the Guest acct. on the same computer. I was thinking I'm sure there's some way to log into the guest, and then run admin in it and then transfer it over, but I haven't figured out how it's done yet. thanks for any and all help and sorry if I went on too long about it!
