I have a Kobo e-reader which I like because it is small, exceptionally portable and when you use the light for the screen it does not glare. I find that better for reading text. The dictionary function is excellent ,and, all in all , it suits me well. I had not connected it to my Steam Castle PC which has an OEM version of Windows 10 and a very nice one at that. The e-reader started charging , updating and was showing up on MyPC for about 10 minutes but then it vanished. No amount of turning things on and off worked. It seems to be a problem with Windows 10 having searched for that problem on Google. Except it is not. The Kobo e-reader works perfectly fine on Windows 10 . It just doesn’t show in MyPC. I downloaded the Kobo desktop app which picked up my e-reader for the amount of time it was showing on MyPC. Then I could do nothing other than browse the shop, sync the device and look at my account. There is , however, a Kobo universal reader app which you can download from the link on The Digital Reader for Windows 10. I downloaded that. It comes up in the Start Menu as Kobo eBooks so you have to be careful not to confuse it with the Kobo desktop app which just comes up as Kobo. The app is very easy and cruisy. The interface is very clean and the menus top and bottom do everything. I could sync my e-reader, add new .pub and .pdf files, which I really wanted to do, and browse the shop. I can export files too to my desktop. It works very well and in a fuss free manner. Within 2 minutes of loading it I could navigate and use it. There is nothing mystical or troublesome about it. So, it didn’t matter that it was not showing in MyPC when I used the free Kobo eBooks app from the Windows store.
