I compiled a win10 msieve r1044 binary, CPU is an i5-1135G7.
Brief install step is:
1. Install tool cygwin64
2. Install gmp (using download method).
3. Install msieve (using make method).

I'd suggest to do the 'NFS Filtering' step 50 hours first , to look what will happen then. Since the relations count is 2000 million, it will meed more patience than 1000 million.
