I upgraded to 10 on my laptop. After a couple of days i reverted back to 8.1. I uninstalled the update to get 10. Now i want to install 10 on my laptop again. I installed the get windows 10 update. It says windows 10 is downloading in the back ground but it's be like this for 4 days now. Anyone know why? Can you not revert back to 8.1 then back to 10? It's not that big of a deal. I like 8.1 okay. Thanks....
