changing HDD letter and path

[oscarcat]

I'm sure this has come up before but I'm after more detail.
I have a new PC. My 'C' drive is a SSD. A second 2 TB HDD was assigned 'E'.
I will choose, where possible to load apps onto 'E' because of the size restrictions of the SSD.

So far I've been hold back but have installed MS Office 2010 on 'E' and the Canon software for a Pixma multi-function.

I have now installed 3 more, 1 TB HDDs (from older PCs) and one of these is 'D'.

I'd like to change the 2 TB drive to 'D' and change the existing 'D' to 'E'.
Microsoft issue a warning that some windows apps will have problems if a drive letter is changed but don't specify any.

If I do change the letters, will this cause problems with the path to the Office suite?

If problems do arise, does reverting to the original lettering resolve things - or is the registry well and truly screwed by then? Would getting a registry backup done and having it on the desktop be of any use?

Don't change drive letters if some progarm is pointing to it!! Change it back using disk management. Name is D or E... who cares. leave it as it was!

What folders do you want to move from C to D (or E)? Whole "program files"?
