I agree. W10 is total garbage...I bought my son a brand new Lenovo
laptop and it was slow as Christmas with all the bloat and Mcafee installed.
The bloat has got nothing to do with Windows 10. If it had come with Windows 7 preinstalled, I'm sure it would have just as much bloat installed. You complained about McAfee, but these days it doesn't impede performance much and if you don't like it, you can easily remove it. It's worth noting too, that the laptop has a lower price because of bundled junk. If Lenovo was not making money from the included extras, they would have to raise the price.
You can make the laptop run faster by doing a clean install of Windows 10 (or even just uninstalling anything you don't want) and as others have mentioned, replacing the hard drive with a SSD. Also upgrading to the maximum of 8GB of RAM would most likely help too. After doing that Windows 10 would be really fast on that computer as its CPU is quite fast. I'm running Windows 10 on some laptops from 2006 which have much slower CPUs and it runs very well.
I will always stick to the best OS ever made other than XP which is W7!
On that laptop, Windows 10 will run just as fast as Windows 7, if not faster. Bear in mind that support for Windows 7 ends in January of next year. After that, there will be no more updates released, making it more vulnerable to being infected, so it makes sense to run Windows 10 rather than Windows 7..
Also, you missed the humor in Spawn's post. It was a not a serious post, he was just listing some of the things that people like to complain about in regards to Windows 10, that aren't actually true.
