The performance measurement is not a true one.
There should be a way to reflect to the hassle and the headache that Microsoft enforced people to live through with this upgrade.
My Lenovo twist was working perfect with 8.1. I was totally convinced that it was the best ever Microsoft OS.
I read this article, and with the free upgrade, and the new touch features Microsoft promised, I went through the upgrade .....
The performance suddenly became BAD, and kept going from bad to worst.
I checked almost every technical article to resolve problems, half of them never worked with me, and still waiting for answers
My tablet used to restart in 5 seconds, not 2 minutes and 18 seconds; this is until yesterday, and after 4 days of suffering and agony.
Even when I rolled back, 8.1 is never working the same ....
Some apps don't work ... most importantly Windows Update ... it still insists that I should upgrade to Windows 10 for FREE ... as this word is the catch that will convince everyone to become Microsoft Rat Lab.
I reached to a point where I signed a petition for Bill Gates to fire all executives in Microsoft and get back to behind the steering wheel of this company, because those guys are ruining everything.
Just wanted to share this with you all. Hopes you never face this
