There are still things from previous versions and other OS’s that would make me upgrade to the next/best just for convenience – maybe MS could almost do a ‘best of’ feature set to get back some old time enthusiasts as well.
Folder thumbnail preview – in XP you could add ‘Folder.jpg’ in order to see a full size thumbnail preview for your folder or you could just see a selection of folders – in future version you only get to see half a thumbnail preview or simply a stack of your images which are in no way as clear as XP’s precise view of what you was looking for visually.
More control over the taskbar: With older versions I could use the Quick Launch toolbar to keep static icons in place, following versions move icons as you open multiple windows within the shortcuts application – my brain knows where its icons are and always liked to go to the same point to select them.
Allow us to make the taskbar non transparent – I’m so sick of seeing items that are half way off my screen still visible when I’m editing another document in full screen mode whilst using Win 8.
Allow me to organise non html based shortcuts in IE – I know there is currently a bug report in place - https://connect.microsoft.com/IE/feedback/details/808697/ie11-favorites-bar-bug-local-html-file-links-are-automatically-pushed-to-the-bottom-of-the-list - but come on, it should be sorted by now – you are Microsoft!
Put everything that requires change as a simple icon in the control panel – why do I have to go to obscure settings in order to make changes?
Some things you do are so great, why take away features or make it so unintuitive that even long term users become frustrated and annoyed. What basic features would you like to see? Im sure most of us don't want the world, just simple little things that make us love Windows.
