To say that Microsoft have made Windows 8 less efficient at multitasking than Windows 7 is a total nonsense - I feel sorry for Microsoft employees and developers who have to put up with all this disinformation that floats around about their products.
Here's a list of the things in Win XP / Vista that did not impress. Are they back in WIn 8?
Search function - Windows XP/V search requires indexing, which I refuse to enable as it spends an inordinate amount of time looking through my files for the rare occasion I want a file or folder. WHen I do want one, I have to type the filename, then hit advanced search, then click to search locations (said window is not resizeable, not does it offer the option to save custom searches), enable tickbox to seach in non-indexed locations. Verses
this it's pathetic. When I want a file, I want a file. Let's use the hard drive when searching is asked for. Not before. Simples.
Winsxs - Started in Vista, continued in Win7 - Currently uses 31.5% of my 50GB C: installation. NO way to reduce it without severe (and potentially disastrous) hacking of the file system.
Office 2007 ribbon (apparently continued in Win 8) - Hard-coded and created massive loss of productivity, hence, I hacked in the old menu:

After a year or so of use, the ribbon is more useful, and I have nothing against a single bar of one-click shortcuts; indeed the idea is great, but the lack of being able to disable and go back to the old system, or generally configure it at will is bad. Like having the Win taskbar only at the top all of a sudden. I like it at the bottom, and want it to stay there.
So is the taskbar gone in Win 8?
There are probably a couple of dozen others, but after 3.5 years of fiddling, I've ironed them out. I don't think I fancy fiddling for the next 3.5 years for Windows 7 / 8 or any other Windows OS. If I can figure a Linux setup with MS Office, that will be my next system.
