I have less issues with W10 than prior versions. But about trust. Do you mean security or what exactly?
I got a new HP PC for over a month, from day one, the pc is some how lagging, stall within page loading slow, most time while you reading an article, in half way, you need to wait the page load before you can get the rest come up to the page. contact the tech support from internet, told what the problem was and the tech done everything from their end to try to fix my PC, seems work for day or two, then, same problem, also, I think the front USB plug is not working at all because I asked how to down load the pics from my cell to PC, inserted the USB cable at front, not work, have to use the one at back, OK, he did loaded the pics from cellphone to PC, got the file set from their end, but when click, no pic at all, so, the tech said its the soft ware problem, he can't do anything. gave another number to call, at this point, I think its better send the PC back to HP for repair then just contact the tech support again, last year, I had a new laptop also did run very slow since day one, called tech support can't fix it, but sent the HP for repair, since then, no problem.
I just wonder, window 10 seems has more problem then any other like 7 or 8, even its new, Can we still trust the window 10 ?
