well it cant be done that way at all.
lol i dunno what the hell your trying to do but it won't work.
ALL OF THE PROGRAMS WONT WORK !!! (properly)
God just back up the files you need to different Hard Drive or partition and reinstall.
Its windows we're talking about it is impossible to do it EVEN if you could it would be half assed job which would be unstable.
windows installs in a folder called windows if tht folder exists then you cant do anything about.
Just back up your files and start from scratch that way you free up your PC it will be faster as well and you get rid of unwanted programs and files that have been left behind(like there always )
TBH i think the way your doing or wanting to do it is bad for system and also stupid
No offense but i never ever done it that way and wouldnt advise anyone else to either lol.
