There are windows zip files in github:
32 bit - https://github.com/strcoin/starcoin/releases/download/v1.7.1.0-str/starcoin-1.7.1.0-win32.zip
64 bit - https://github.com/strcoin/starcoin/releases/download/v1.7.1.0-str/starcoin-1.7.1.0-win64.zip

edit - it takes a long time for the wallet to open, so just be patient.  Just let it run over night.  If you have addnodes, it will open and sync eventually. There is probably a ton of bloat in the block chain from millions of .001 STR minting transactions.

For nodes, I'm using:
addnode=107.170.3.87
addnode=95.27.95.182
addnode=173.208.172.242
addnode=50.149.31.242
addnode=192.99.13.127
addnode=54.209.148.72
addnode=201.213.232.241
addnode=124.198.136.100
addnode=107.170.195.237
addnode=74.208.250.49
addnode=198.199.110.176

Good luck
