I just finished upgrading 4 computers to W10, an adventure to say the least. The play-by-play rundown:
HP Laptop– A pretty smooth transition, Microsoft decided that since it is a laptop I didn’t really want to use the Nvidia graphics. Easy to fix once I found the problem.
Main Gaming Computer– Again pretty smooth. The graphics were all wrong initially but a simple restart and all was well.
[This isn’t so bad, what can go wrong?] When will I learn never even to think that!
The little machine that runs 24/7 keeping 3 bots alive in Brocade– Installation went well. The desktop flashed continuously, impossible to interact with anything! Contacted Windows Support, “Help, call me asap!” They got back to me within the hour and after spending over 2 hours poking around on the computer he deleted every file and folder that even suggested Norton or Symantec. Problem resolved. Reinstalled Norton antivirus and everything was still good. Lesson learned: No matter what Micro$oft says, manually uninstall antivirus first!
The older machine I use for general surfing and graphics while I am in SL– Install would not run at all, error code. Back to Windows Support. This time it took a couple of days for a response. Level 1 tech spent 4 hour before giving up and passing it off to a Level 2 – (2 day wait for him to call back). Another 3 hours of watching the cursor do things “by itself”. Stumped. Call back the next day. After an hour or so, we decided to do a clean Windows 7 installation. Another day while I did that and ran updates half the night. Tech back one more time to validate the installation and I was able to upgrade!!!!
[Whew! Finally all set.] I never learn!
When reinstalling apps I discovered that Windows did not recognize the DVD drive — On Any Of My Machines!!!!!! Back to Tech Support. After a couple of hours figuring things out he solved the problem and gave me a snippet of code to fix it on the other machines.
All told Microsoft invested over 12 hours of Windows Tech Support time getting me up and running. Obviously not sustainable, hopefully they are learning and modifying the install to avoid the problems. I have to give the tech guys high praise, they are overwhelmed atm, working 7 days / week, and yet they were polite, helpful, and very persistent.
As to Windows 10 itself; YAWN Once I turned off the various spyware features and got rid of most of the unwanted tiles and apps, it runs virtually the same as W7. Some people say SL runs better for them, for me it was much the same.
