I suggest to stick to the words of the PEP, which means that XP needs to be supported in 3.4. For 3.5, according to the PEP, XP support *may* be dropped - it doesn't have to be dropped. Notice that you cannot yet know for sure that XP support ends on April 8 - even though it's likely that it will. Microsoft might (and, in the past did) extend an earlier end-of-support date (although they probably won't do so for XP anymore). The most significant reason for dropping XP support in Python will likely be the desire to switch to new VC versions: Newer CRTs don't support XP anymore.

Win7 is now our default desktop for new machines, but we're still running a slight majority of WinXP machines.

The first thing that the PEP says about unsupporting code is: Unsupporting platforms If a certain platform that currently has special code in it is deemed to be without Python users, What a vendor supports is only a heuristic. Existence of users comes first. Note that the policy says that some Windows platforms *will* be supported. It doesn't say others will be unsupported (except implicitly: 3 years after the last version of Visual Studio capable of building releases for that platform goes out of extended support, the build infrastructure will be removed).

Why have the specification in PEP 11 if we feel we can change the rules arbitrarily when we feel like it? Because process PEPs are documentation of community practice, not an inviolable constraint (e.g. PEP 1 has frequently lagged behind what we *actually* do, and only been updated once we noticed we had drifted away from the nominal procedures). In this case, the question of What do we do when a Windows version goes EOL shortly after a Python release? hasn't come up before, so PEP 11 has never had to take it into account. That doesn't mean we *should* change it, it just means the option is one we have available to us. Fixing issue 6926 only requires setting the minimum API version to Windows *XP*, so it isn't actually relevant to the question of whether or not to drop support for XP (only W2k, which I thought we already dropped, but we mustn't have bumped the minimum Windows API version at the time). Issue 1763 looks like it could be better solved through pywin32 than through standard library changes. It certainly doesn't appear to be worth the cost of dropping Windows XP support. Unless there are more compelling examples of APIs that we can't access through Windows XP compatible interfaces, -1 on the change for 3.4.
