I checked my Windows Update ..... and there it was....ready to install... all 2.7GB of it.
I have the Win10Pro Version .... so I have installed it ... took about 30mins to do the upgrade from Win7 64bit Ultimate.
I customized my install to suit myself.... turned off all ' suss ' data sending Apps and location sending....

I still use Firefox and many of my own Media Programmes.
I checked ' Device Manager ' ... everything is good...all drivers accounted for.... no ' unknown devices ' showing.
It ' appears ' to be quite fast ... boot up time is quicker, although I'm running an i7 Processor at 4Ghz / 16Gb DDR3 Ram.... that certainly helps.
I had no issues at all .... detected my Internet connection / Wireless Printer / WD Cloud Storage connected at Modem Router.
So far I'm happy... found my way around it after ' playing ' with it for an hr or so.
It's all good here.....
