What they said originally about Windows 10 is right. It needs lots of RAM. It also appears to need a clean install and they said that too. My other version of Windows 10 was an upgrade from Windows 8 on an 8Gb computer. It improved Windows 8 , it ran okay but there were problems. The taskbar dismantled its function early on in the piece and no updates or fiddling around has ever fixed that. I installed a 3rd party start menu and at least got that functionality back because I lost the tiles as well. The customisations have held that version of Windows 10 together. It has been okay. Just okay. My Steam Castle has 16 Gb RAM and is very much graphics dedicated. It has an OEM version of Windows 10. I have Cortana, a functioning taskbar, the tiles in the menu and it all runs very efficiently and smoothly. Updates are fast and I am not there for ages waiting for downloads or installs. They do not take any time. This version will put up little pop ups bottom right about what is happening on my computer and that works well for me. The messages are by way of Did you know? Do you want to do anything about it? Just letting you know… That is all very helpful. Everything runs well and I can access everything easily. What I can’t find Cortana does and I use it like Apple Mac Spotlight . Now I have seen this version of Windows 10 I am more than happy with it and it is a pleasure to work on. Visually it is very good and technically it seems to be in control of everything. With Windows you get used to odd things happening and you just carry on anyway. This version of Windows 10 is competent in its capacity to function and troubleshoot.
