What do you mean by on a remote wireless keyboard?
Are you using the Seeda keyboard on the computer that's remoting into another computer?
If you are hoping to find the Windows key on Seeda keyboard, that's not a Windows question, but more specifically to Seeda. Some compact or multi-device Seenda keyboards (especially for tablets/Mac/iOS) may:
Replace it with a Fn (Function) key combo
Use another key as Windows when switched to Windows mode
Try Fn + another key (need to refer to Seeda instruction)
Check for a mode switch (Windows / Android / iOS)
What's the exact model of the Seeda keyboard?
