\S{faq-ports-general}{Question} What ports of PuTTY exist?
-Currently, release versions of PuTTY tools only run on full Win32
-systems and Unix. \q{\i{Win32}} includes versions of Windows from
-Windows 95 onwards (as opposed to the 16-bit Windows 3.1; see
-\k{faq-win31}), up to and including Windows 7; and we know of no
-reason why PuTTY should not continue to work on future versions
-of Windows.
-
-The Windows executables we provide are for the 32-bit \q{\i{x86}}
-processor architecture, but they should work fine on 64-bit
-processors that are backward-compatible with that architecture.

+\#{XXX-REVIEW-BEFORE-RELEASE: The 64-bit executables will only

+than 32-bit executables would on the same processor, but will
+consume slightly more memory.}

(We used to also provide executables for Windows for the Alpha
processor, but stopped after 0.58 due to lack of interest.)
