note that the msi installer is redis-64, aka the windows port; support on that is patchy since the department they was doing that no longer exists.
Frankly, if you're using redis on Windows for local dev purposes, IMO the easiest way to do that is to use the Windows Subsystem for Linux on Windows 10 (aka "bash on Ubuntu on Windows", although more flavors than Ubuntu will be available very soon). This lets you use the exact same instructions as for "regular" redis on Linux, because *it is*. It also means you can use 4.* etc features.
But let's assume you can't use that for some reason...
If you have installed it as a service, check your services list. If there's a redis one: start it. Then run "redis-cli" at the command line. If you haven't installed it as a service, then: run "redis-server" at the command line. If these tools don't work, I blame the MSI. I always use cinst for this, i.e. "cinst redis-64" (job done).
