Use your razor blade to "get it started", then spritz some solvent
(WD-40 or lighter fluid works well, I've found) into the gap between
sticker and glass. Give it a minute or three to work, then use your
razor to increase the "start", and repeat the solvent application/wait
process. Repeat until sticker is gone. Wash off any adhesive residue
with solvent, and you're done.

Your chances of scratching your window with a razor blade - ANY razor
blade, are pretty slim - glass is harder than all but specially hardened
metals/alloys, and I can't see any realistic chance of a finding a razor
blade constructed of such material. Even assuming that such a beast
exists, I'd be *VERY* doubtful about anyone going through the time,
effort, and expense needed to harden it to the point where it would be a
threat to even the lowest quality glass.

You mention acetone - A lot of plastics (not all, by any means, but a
decent number of them) will literally dissolve, like sugar in hot water,
when exposed to acetone. That may be another option for you, depending
on exactly what formula of plastic was used to make the sticker.

The razor-and-solvent method is a sure bet, though.

It should go without saying that you probably don't want to get any of
your chosen solvent on the paint-job unless you're an admirer of the
"streaks and dribbles" look...
