I finally got the upgrade updates to windows 10 for my computers today.
Got it installed on my laptop and my desktop and running ok on both. However, a few notes for anyone about to do the upgrade:
First on my 4 yr old high end gaming laptop it was smoothe sailing, had the OS installed and everything working in about half an hour. My older desktop (8 years old but with a newer video card) had a few problems, first windows installed a driver for my Reatek network card that just didn’t work so on upgrade I lost internet access until I was able to go in and find device manager to manually remove the driver, find a driver and manually install it (even then it didn’t work until machine was restarted twice - why I have no idea) it also couldn’t install a driver for my Nvidia GTX 750 Ti video card, had to manually install that one too.
Also I have found quite a number of basic features of the new OS that just don’t work (try going into windows defender to tell it to exclude a folder or file from scans and you will see what I mean) other things work fine on my laptop but not my desktop (things like, windows update and the backup program to name a couple).
It is a lighter Os than 7 or 8 and they seem to have removed a lot of unescessary code (as well as the recursive code that overloaded memory over time and forced you to restart windows every week or so).
Overall one of the best upgrades for windows I have seen yet, the probelms seem smaller and the final product looks and acts pretty much like the previous one but a bit faster and with a few more features (although fewer than advertised at the moment).
Just my experience so far, your mileage may vary.
I managed to get a number of features working on my desktop in Win 10 by reinstalling over the OS with itself. I now have windows update and system restore working.
The OS is designed to better use what hardware you have, so if you have 3 GB of ram it will use 2.5 GB and if you have 16 GB it uses 11 or 12 GB. The processor usage shouldn’t be above 20% without active apps running and my computers sit at 8% and 7% at “idle” for my laptop and desktop, repectively.
If you are seeing exessive CPU usage it may mean that win 10 is still setting itself up (cataloging drivers, indexing apps, etc) which take a few hours after install to complete (my old desktop took a good five hours for this to finish).
I guess I should have mentioned that I installed Win 10 on a laptop weeks ago and played with it for a few days before doing a complete HDD wipe (low- level format included) and reinstall of my win 7 / ubuntu so that I knew which “features” needed to be turned off on install and which switches and options I wanted. BTW, you can only do a clean install if you have a full version key for win 7 or 8. Since I had only upgrade keys (since I updated from XP) I had to wait for the MS upgrade push. If you do have a full version key (or want to pay over $100 for win 10) then you can download an iso of the OS from MS to do a clean install.
