how do i chage my skin on Minecraft windows

There is something on Planetminecraft that allows bạn to change your skin

Download the skin mod and choose whatever skin bạn want. Then go to minecraft.org and hit đăng tải skin. And there bạn go

I believe I can be of thêm assistance.
I recommend downloading a Minecraft skin maker app on your iDevice. If your skin maker app happens to have an autosave function, bạn should know that there's no way of deleting this. It will automatically save every pixel bạn chỉnh sửa and will be a lifesaver, should the app crash at any được trao moment.
The app is easy to use. bạn can choose from a variety of premade Skins and chỉnh sửa them.
Know the Minecraft tên người dùng of one of your friends, hoặc a different person? bạn can tap "Search bởi username" and bạn can type in the username. Be warned; tìm kiếm bởi tên người dùng is case-sensitive.
Once the skin is edited to your liking, tap the "Preview" button and find the "Upload to Minecraft" button. This will swap out your current skin for the skin bạn just uploaded to Minecraft.

bạn can go on Planet Minecraft, go to skins, and tìm kiếm what skin bạn would like, click one then scroll down to find "Download" then click Change My Skin! and then log in, and your skin is there! :D
