I've got a machine that is 64-bit, running 32-bit windows 7, which has 8GB ram.
I did the official upgrade to windows 10 that Microsoft was offering a few weeks ago, but I'm having a difficult time setting up the /pae boot option, which I have been lead to believe will allow me to use more than 3.5 GB of ram.
Is it possible to set up the /pae option to address more than 3.5GB ram on a windows 10 system?

According to this guide, you can use PAE to allow more than 4 GB of RAM to be used by a 32 Bit OS. But i am not sure Windows 10 still supports PAE and more than that, is does not make any sense to struggle with a 32 Bit OS in 2015, when all PCs are 64 Bit. He should go for 64 Bit.

1Windows 10, 32-bit fully supports and uses PAE. However, it is still limited to using 4GB of RAM. This limitation comes from the fact that 32-bit kernel drivers only use 32-bit pointers into kernel memory, and so can only address 4GB. Windows 10 doesn't support having kernel memory that drivers can't access. – David Schwartz – 2015-11-23T14:15:52.317
