In this video I install Windows 10 Technical Preview (Build 9926) on my Acer Iconia W4 tablet, its a very simple and straight forward upgrade from Windows 8.1 Pro.
Just downloaded ISO file from Microsoft:
http://windows.microsoft.com/en-us/wi...
Extracted in C drive using winrar
Ran the setup.exe
followed the instructions
Problems so far:
1. sometimes Start menu does not open and does not open at all on Administrator account, this is a well known problem on this build of Windows 10
2. Generally the OS felt very sluggish occasionally the touch malfunctions.
3. Screen scaling issues and blurred text in certain windows
