Happens when saving a draft.

Which blog host are you using? That might help the developers.

This is caused because OLW is using the same file extension (.wpost) as WLW and there is code comparing AppUserModelID for Windows Jump List registration. The following code does a comparison to make sure you are adding to the right jumplist:
https://github.com/OpenLiveWriter/OpenLiveWriter/blob/master/src/managed/OpenLiveWriter.PostEditor/JumpList/JumpList.cs#L222-L226

Since the AppUserModelID is actually WLW for the .wpost extension it fails and is getting noisy.

Options: remove JumpList support or change file extension.

Personally speaking, I'm ok with removing jumplist support as I never use it, although it depends on how much others use it I guess.

Using same file extension is not a problem. Most of us have more than one web browser installed side by side and any of them can open html files. The issue here is that OLW is not registering itself as an app that can handle .wpost files, which is a requirement to use the jump list. Normally such registration is done by an (msi) installer, but I don't think Squirrel is capable of doing that. If anyone is interested, there is an article on the MSDN detailing what needs to be done to become a default app - Default Programs.

Removing JumpList would be the easiest (and potentially the only) way to solve this, just changing file extension won't help.

Just a quick note to say that I am a user of the Recent Drafts Jump Lists.

Often for my Channel 9 posts, I'll draft a post and when the video is encoded (hours later), I go back to it and finish it up. In the end, I currently use the WLW Recent Drafts Jump Lists 3-5 times a week. It just makes it a few clicks easier to bring up the post in question.

That said, I understand the issue and think I could work around it with File -> Recent Posts...

[humbertoc26]

It seems like this behavior was removed from OLW.

Shouldn't it be fixed instead?

[scottharner]

Is there a work-around for the draft saving bug on Windows 10 in the absence of a bug fix?

This happens when attempting to publish as well. I'm on Build 0.6.0.0 en-US.
