We had already done this:
But the installer has gained weight again:
Xpra-Python3-x86_64_Setup_2.4.3-r21365.exe 2019-01-15 06:47 53M Xpra-Python3-x86_64_Setup_2.5-r22135.exe 2019-03-19 16:21 95M
The 3.0 builds are over 100M
Bundled icon trimmed: #2563
Most of the remaining weight is from the cuda library (~40MB!) The 32-bit builds don't have CUDA and weigh around 60MB.
As for the rest:

The next big saving would be to ship a trimmed down avcodec DLL.
