Modifying folder locations before windows installation

[inkognito]

1. I would like Windows not to create a different folder for each user, but to use one Desktop, one My documents, Temp, App Data and so on for all users. I actually do not need more than one user and I do not want Defaul User and All users folders to exist separately - I want just ONE App Data folder, one Temp folder, one Desktop, one Start menu folder. Is it possible to tweak Windows installation files - to set folder paths, replace "%currentprofile%" (something like that) with ""... In other words, is it possible to change paths BEFORE installing Windows - I can change Documents and Settings, Program Files, Temp and Windows install dir in nLite, but that is not enough for me - I want more paths to change.

3. And I would like my start menu to look not like Start menu>Programs and only then all installed software shortcuts, but like you click on the start button and see everything that normally is in Programs sumenu. I've tried to set Start menu\Programs as Start menu folder, and then I get what I want - I see all shortcuts that are in Programs subfolder directly in the main Start menu, BUT I also see Programs submenu and it shows the same programs - I want Programs submenu to disappear, since I already see those shortcuts in the Start menu.
