Windows 7: How do I move my user profiles back to C:\user

On advice here to keep OS disk space small, followed the tutorial
User Profile - Change Default Location
and moved my user profile from C:\user\name to E:\user\name

The problem is Windows upgrade (need to run for repair) will not accept profiles being on separate partition to the OS.
Also it will be an issue when I need to upgrade in future ... Don't move your Windows user profiles folder to another drive | ZDNet

I need to move my profiles back, anybody got any tips for doing this ...

Although user profile is on E:\ there is also some files under same name on C: even though they were moved as per tutorial.
I assume it would be best to merge ... (may be appdata items)
I tried the copy active profile ... but when I opted to copy & merge it with C:\users\name it blocked telling 'file is open in System'


Do I need to log on as a different user to allow me to merge the files ?

Any help on steps\ sequence appreciated.

Did you try "Method 2" of the tutorial you referred to.

Did you move c:\users\your_account_name totally to E:\..... ?

I want to do that ... the issue (I assume) ... I will have to logged in as admin and different user to do this, do I allow profiles to 'merge' ... just concerned if I don't merge will there be some key appdata items lost.

User Profile - Change Default Location
check if registry setting still correct!
Did you do step 16 (it deletes profile on C)?

when I initially did this (over 18 months ago) yes ... since then 'some' profile items seem to have crept back in.

Just too alook in what is within teh C:\ profile ....

Some 'Wondershare entry' in appdata I can live without but aslo an Adobe folder in 'desktop' which contains historical versions information for Lightoom ... so again probably can be overwritten, or can I merge ?

Can you show screenshot with filenames that are on C without your knowledge.
Or did you do a half merge already?

this shows contents of the folders I described above as within my C:\ profile

As to Lightroom I now use a newer version, it must 'keep' these historical bits.

I'm going off-line now ... but happy to carry out any steps you suggest tomorrow morning.........

All Contents in C:\users\Rick\desktop is on your desktop as well?
