Like the fact that Microsoft chose to implement HTML 5 and dumped any integration (that I could find...) that enabled Flash.
That right there is going to be the end of Flash (which deserves to die by death of a thousand cuts!) and all the insecurity/vulnerabilities it introduces.
I've been on Windows 10 since the Developer Preview and really like it now. It's much faster, the CPU and Memory processing requirements to support the OS are actually quite low as Microsoft seems to have optimized the OS Code throughout the development cycle of Windows 10.
Still don't like how they re-implemented the Start button and I choose to use Classic Shell as a replacement but overall I'd say Microsoft has a winner on their hands.
I've been updating and patching the 12 desktops, laptops and servers in my house since Monday getting them prepped and ready. They all now have the Windows 10 Upgrade icon in the status bar, which was the goal of getting everything patched up. :-)
If classic shell is available I feel better about 10.
I have a cpmputer savvy young man that helps me and can guide me...He LOVES 10.
