Hi, Piotr.

Let's get more specific on a couple of points:

> Tried from both OS'es (XP and Vista); tried taking ownership;

Ownership of what? Owned by whom?

Can you create a new User (if you haven't already) named "Piotr" (perhaps),
and have that User take Ownership of the entire drive, or, at least, the
entire \Windows.old folder? In my experience, this took much longer than I
expected because it had to take ownership of each file and folder, one at a
time. But when it finally ends, the User Piotr should be able to delete the
folder.

Let us know, step by step, exactly what you did and exactly what error
message or other result you saw.

In the Command Prompt window, what command and parameters did you use? As
I'm sure you know, we don't "delete" a folder, we "remove" a directory. If
we enter simply "rd \windows.old", we probably will get a message that the
directory is not empty. If we append the /s switch, it will try to remove
the entire directory tree, including all subfolders and files, even though
not empty - but it will first ask us "Are you sure".

Again, please tell us exactly what you typed in the Command Prompt window
and exactly what results you saw.
