how do i chage my skin on minecraft windows

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

Download the skin mod and choose whatever skin anda want. Then go to minecraft.org and hit upload skin. And there anda go

I believe I can be of lebih assistance.
I recommend downloading a minecraft skin maker app on your iDevice. If your skin maker app happens to have an autosave function, anda should know that there's no way of deleting this. It will automatically save every pixel anda ubah and will be a lifesaver, should the app crash at any diberikan moment.
The app is easy to use. anda can choose from a variety of premade kulit and ubah them.
Know the minecraft username of one of your friends, atau a different person? anda can tap "Search oleh username" and anda can type in the username. Be warned; cari oleh username 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 anda just uploaded to Minecraft.

anda can go on Planet Minecraft, go to skins, and cari what skin anda 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
