after XP support ends then Adobe *may* not provide an update for XP
As I've said a million times before on the subject, its not a case of the third-party vendors providing updates for their products, otherwise anti-virus etc. on XP would be a viable option.
The problem is that anti-virus, Adobe and every other software package is running on top of the Operating System and are dependent on it and its APIs (developer coding interfaces).
As a result... unsupported, obsolete and vulnerable Operating System equals vulnerable software.... no matter what the software or whether its developer is still providing updates.
