> When setting up the blog, it also check what features are available with your blog. However, I find it useless.

This panel is mainly for debugging purposes. The algorithm we use to figure out what capabilities your blog has is complicated, so this is an easy way for support people to figure out whether a feature should be showing or not (we try to hide features that are not supported by your blog).

> For example, for File upload, I cannot really use it since I can’t upload images to my wordpress upload directory.

This could be due to a PHP bug that we’ve seen on some configurations. Writer generally works fine when uploading images to WordPress. E-mail me and I can help you get to the bottom of this.

> And I don’t even have clue about comment policy, and author field. There is no such field in the editor for me to enter my name.

Comment policy and author are available at the bottom of the screen. Next to “Set Categories” and “Set Publish Date” there’s a little up-arrow, which reveals more post options.

> However, the quality for resizing doesn’t seem good enough. It’s getting really blurry.

Yes, we have an image processing bug that’s causing that. It will be fixed in the next release.

> One thing is really bothering me. Whenever I press the return key, it just generate a tag to wrap the paragraph. This is annoying. I am a person. It’s just make me feel that the code it generates is not clean. Just like the FrontPage or Office Word. It inserts a bunch crap code to take the space.

Actually most web standards advocates consider tags to be much more semantically correct for separating paragraphs than ; that’s why we do it. If what you actually mean is , you can use Shift+Enter.

> It also allows me to add category and tag. However, it doesn’t allow me to add custom keywords and description for meta tag

I believe you can do this by filling in the Excerpt and Keyword fields. These are in the same panel as comment policy and author (see above).

> However, when I have more than two windows opened the same time, and with real-time spell check enabled, my CUP usage is going crazy. It slows down my entire PC. I close all of the running application and still get 70% CPU usage and 94MB memory usage.

That must be a bug–we have never seen that before. Unless the CPU usage is coming from svchost.exe, not WindowsLiveWriter.exe. If it’s the former, the workaround is to go into services control panel and disable the Windows Live Setup Service. If it’s the latter, can you please e-mail me?

Thanks again for the feedback–it’s how we get better!
