Not sure if this has been covered before, sorry if it has, however hear goes.
I am running Window 10 on a Spare rig that I built up, Basically an E6500 running at circa 3GHz with 4gb memory. So, basically I am only using Windows 10 as an occasional play thing, nothing more. I've just installed 10056. 10041 to 10049 went ti*s up during an update.
I would love to duel boot via a second Samsung SSD on main PC and really use Windows 10 on a daily basis as my main operating system, this would be used for Games, Internet Browsing, basically general use. This way, if any issues crop up (and yes they always find me) I can simply revert back to Windows 8.1 within seconds. All my data, documents, music, photos are installed on additional SSD's.
But here's the problem, programs that I use such as Microsoft Office 2010 Pro etc are paid for and installed legally on my main PC running Windows 8.1 Pro. So I am NOT able to test these on Windows 10. I would swop the likes of Office over to Windows 10 if it was 100%, but for security/safety, I currently feel I need to keep it installed on my Windows 8.1 installation.
