xp32, surprisingly, has more uninits than xp64 or win7:

start up and shut down:

1.5.0:
ERRORS FOUND:
0 unique, 0 total unaddressable access(es)
6 unique, 29 total uninitialized access(es)
0 unique, 0 total invalid heap argument(s)
4 unique, 61 total GDI usage error(s)
0 unique, 0 total warning(s)
31 unique, 31 total, 2668 byte(s) of leak(s)
0 unique, 0 total, 0 byte(s) of possible leak(s)

1.5.1:
ERRORS FOUND:
0 unique, 0 total unaddressable access(es)
6 unique, 46 total uninitialized access(es)
0 unique, 0 total invalid heap argument(s)
5 unique, 71 total GDI usage error(s)
0 unique, 0 total warning(s)
31 unique, 31 total, 2668 byte(s) of leak(s)
0 unique, 0 total, 0 byte(s) of possible leak(s)

but Qin hit a bunch of button and got xp32 calc up to:
0 unique, 0 total unaddressable access(es)
174 unique, 434 total uninitialized access(es)

this is another issue filed for "try to get to zero false positive uninits"
