Hello
Unfortunately there's no way to simply switch the plan holder from one account to another.
Your wife needs to cancel it from her account. Please go to https://account.live.com
Sign into her Microsoft account. Then go to Services. Click on Manage for the subscription plan you want to cancel.
Then you just need to subscribe it with your account, and then share with her and others.
