Changed from AHCI to IDE and then back, do i need a windows reinstall?

Hi all.
When i installed windows my bios was set to AHCI.

I needed to switch to IDE temporarily (had to do some tweaking to my WD green drive).
Booted windows and it installed some drivers etc.

Then i went back to bios and switched back to AHCI.

Any harm done to my system?
Anything i should check or worst case, a reinstall windows?

Thanks.

How is Win7 performance now? I would go by that.

The short simple answer is no.

The long complicated answer would be no, with a but.... as anything is possble in computers.

Bottom line is no.

Thank you.
