For me yes, it literally builds all the stability and the future of our Windows installation. If you are someone who reinstalls often, I advise you to make clones. Windows Vista RTM is a stable bone, you just have to know that some services crash but you can restart them to fix them. For example the control panel can either not open or be empty, it is these services that must be restarted: net stop EMDMgmt net stop slsvc net start EMDMgmt net start slsvc If we master Windows Vista RTM well after it becomes our friend and if we correctly sort all the updates to install, it becomes as clean as an arch linux.
