Windows 10 messed up my laptop

<p>I recently upgraded to windows 10 and my laptop is like a tortoise right now. i wish I had never upgraded. The laptop is so slow that i feel like i am use the computer of 20 years ago. Please microsoft do not dump your software upgrades on us before they are properly tested. </p> <p>Should this be because of compactibility, why then force this upgrade on us. I have been resisting the upgrade for the last 6 months. I am now messed up. opening a website which used to take 2 seconds now takes 10minutes if at all it opens. i now have to take my laptop to a technicians and incur a cost for nothing. please do not dump products that do not help much before they are tested.</p> <p>Thoroughly disappointed</p>
