danlwd → ROT13 → (no). Maybe Atbash is right for some words:
When I try to decode it:
It looks like your topic phrase is encrypted (possibly a simple substitution cipher like Atbash or a shift cipher). danlwd fyltr shkn qwy bray wyndwz 7 ba lynk mstqym
wyndwz = Windows (w→w, y→i? n→n, d→d, w→o? w→s? no). danlwd → ROT13 → (no)
Check first word: danlwd — on QWERTY, d→s, a→s? Not matching. a→s? Not matching. Actually
Actually, "wyndwz" — if each letter is shifted one key to the left on QWERTY: w→q, y→t, n→b, d→s, w→q, z→a → "qtbsqa" — not Windows.
