How to fix this water damage?
Window moisture problem has been fixed. But how should I fix the drywall damage without removing the drywall?

It looks like a seam that has raised. I would remove anything that's raised and loose. You might need to re-tape that section. Then mud over the damaged area. After that a oil based, stain blocking primer might be a good idea. Then top with a water based latex to match the existing wall. Even with a perfect paint match you might still be able to see a slight difference in the paint color so if you want perfection you might have to repaint that wall or the whole room.

I'd definitely recommend a solvent based primer to hide the water stain - they generally bleed thru latex paint.
I'd also check out the window to make sure there isn't a re occurrence.

Really, you need to start cutting into the damage area to see what you have, what extent the moisture damage is and to confirm that there isnt anything behind the wall that needs to be dealt with, like mold.

Until that it's a little premature to assume that it's just a minor cosmetic repair!
