From scratch:
- 30 minutes to do a fall Macrium Reflect of my existing 8.1 partitions, OS, apps and data to an external 3TB Western Digital over USB 3.0. I was able to simultaneously uninstall all my 8.1 apps that like to phone home (Adobe Acrobat), keep track of license count installs (MS Office 2013 and Visio Premium 2010) and authorize (iTunes) while the image backup ran. In fact, pretty much uninstalled all apps in that half hour.
- 30 minutes to extract the 9926 .ISO to a 32GB, class 10 SanDisk MicroSDHC in a microSD adapter on the SP3's USB port. Used Rufus to make the USB bootable.
- 22 minutes from jump drive boot to Win10 TP desktop with two re-boots at 8 and 16 minutes in respectively.
- Another 15 minutes for the January 27th updates, it stayed on 95% complete a good long while on that reboot.
- Now laying down Visio 2010 Premium and Office Pro 2013 because once Windows Update sees those guys there I know there will be about a gigabyte of service packs and security updates.
This go 'round it's looking a lot "peppier" than the in-place 8.1 > 10 upgrade. I always construct a custom .jpg or .png from
Control Panel > Programs and Features of what I have installed on a machine so I probably have another 2-3 hrs of re-installing another two and a half dozen apps, but all in all not too bad.
One thing I have noticed on my SP3 under 8.1 or Win10 TP is it takes a solid 2-3 minutes after a warm or cold re-boot for the bluetooth mouse and keyboard to be seen and work consistently.
Flip side though is I've got 150% scaling at 2160x1440 on the SP3 and 100% on my external AOC 2963 at 2560 x 1080 so this is a BIG improvement. Thanks to
@jnjroach and others who've pointed out where that setting is.
Cheers, B
