Posts automatically delete with WLW

Assuming you mean Windows Live Writer, it is a plugin that been not updated in more than seven years by an author who hasn’t posted on ww.wp.xz.cn in at least three years: https://ww.wp.xz.cn/plugins/windows-live-writer/

I suggest you look for an alternative. I’m afraid that I don’t have any suggestions, as it is not a problem I’ve experienced. One of my plugin’s users uses the P2 Theme, but that is not likely to work for you.

If you use a private computer where physical security is not an issue, you may want to try staying logged on all the time, and having a bookmark for the Add Post admin panel. My jonradio Remember Me plugin might help keep you logged on: https://ww.wp.xz.cn/plugins/jonradio-remember-me/

kindly help because its difficult for me to post everything via admin panel since i have to post a lot daily..

Can you explain why that’s difficult exactly? The WordPress admin panel is very user friendly and doesn’t need an extra helper to publish content (in my opinion).
