As I stated before, your proposed fix is good because Windows XP doesn't
use the Dynamic DST data.
Thanks,

Hi Masayoshi,
I think the workaround is good, but many customers may not know this
fact and when they need change the timezone, they just select another
time zone which does not support DST and ignore that the auto-adjust
option should be checked first.
To Yoshito, thanks for your information!

I thought Windows XP might (internally) use the Dynamic DST data in
the Time Zones registry for supporting any DST rule changes,
because Dynamic DST was introduced for the US DST rule change IIRC.
But as far as I tested, XP seems to ignore Dynamic DST data. If
that's the case, your proposed fix should be good.
As far as I know, the dynamic DST data is used by Windows Vista/2003
server or later Windows versions.
The registry data for dynamic DST is included in Windows XP time
zone updates, but not used by Windows XP.
