The commands to download and register the Windows agent in the agent registration slide-out were not compatible with both CMD and Powershell.

Avoid compatibility problems with older versions of Powershell that don't support && by splitting the Windows download and installation command into two: one for download and a second one for installation.

Additionally, avoid compatibility problems with Powershell by not splitting the registration command into multiple lines using ^.
