two instances of windows 7

[vint]

I re-installed win7 to fix some issue and by mistake I didn't delete the previous one. Now I've two instances of win 7 installed on C:\>. Is there any way to delete the older version ?

you reinstalled, that is on same partition, right.

in this case, it would have created windows.old at root. If you need some thing out of that you can copy it, else just delete it and you are done.
