Windows 10 - Upgrading Experiences and general first impressions

I've taken the plunge and upgraded my beloved Pavilion dv7 to Windows 10 from 7. I watched with baited breath yesterday to see if anything would happen, after all, I had signed up to get the upgrade and was prepped for it to happen. Nothing happened. I experienced sadness and then I watched my download widget in Rainmeter jump up to 1.5MB/s - our full download speed here. It stayed there for some time and then trailed off. OMG! I thought exultantly that my laptop would then upgrade magically and instantly.... but alas no. Nothing happened again. Anti-climactic was the theme for Windows 10 day. After several hours where I pointedly ignored my laptop and hammered away on the desktop, I patiently waited for something to happen. Around 4pm it did - a new windows popped up and said it was ready. Just a few things to do over 10 seconds, then the install would start. I click on the Go button and waited. It turns out that 10 seconds lasted 14 hours - I went home, slept, came back and the laptop was sitting in the same spot. I killed the upgrade and then a Windows Update "Updating" popped up. The upgrade started again! Oh the excitement! I pointed it out to my fellow IT chaps here in the office. Their response was underwhelming to say the least.... especially as it seemed to stall at 15% - always a bad sign. Thankfully it got going again and my laptop continued to upgrade. Over the course of an hour it completed and now I sit here, typing away in Edge on Google's Blogger. Apart from layout changes and the GUI interface upgrades, it seems a lot like business as usual. The upgrade brought across all my apps, including RainMeter and all the widgets, Chrome and Firefox and all that other stuff as well. I'll play with it over the course of the day and see how it goes. This is a production laptop and I intend to show it off to people so they know what to expect when the upgrade comes through. First up I quite like the new icons and the look of it. The network stuff all looks very similar - there is quite a blend of the Windows 7 functionality and a bit nicer than windows 8 GUI stuff going on. I don't know that I'm loving the Start Menu - perhaps it will grow on me in time. The ads to "Get Office" annoy me - I already have Office 2013! I did have some issues in the preview "Insider" version where scrolling in the Store menu caused it to crash. That seems to have gone away for the moment. I'll keep at it for a while and see how it goes!
