Can't sign into Gaming Account on PC.

If this is on PC are you signed into the Microsoft account that purchased the game, signed into the PC itself.

No. You only need to buy the game once. You would sign in from your account on the PC and your wife would sign in from her account on the console. As long as you have the console set as your Home, she can play the game from her account.

The information you posted means you can't be signed into the same account and play the same game in both places.

Family sharing on the Windows 10 PC is possible, but a bit more awkward than on the Xbox console where you just set the console as your Home Console.

While your brother can't download your Game Pass games himself, you can install them for him like this:

Make sure your brother's account is added to your Family at
https://account.microsoft.com/family

Then let him sign in on his Windows 10 Account on his PC.

Start the Windows 10 Store app, and sign him out of the store.

Sign in with your own account in the store app, and install the game(s).

After the installation is done, sign out of the store and let your brother sign in on the store again.

Be aware that you ONLY sign in on the store app. You do not need a complete own separate account on your brother's PC.

If you sign in on a separate account on his PC, your brother won't be able to access the games you install in your user area on his PC.

Hello, no two people can't play on PC and console, using the same Xbox account. However, the account that buys the subscription can set the console as home Xbox and anyone else can make an account, sign in and use the subscription and any games. The account
that purchased the subscription can sign in and play on PC or any other console.
