Hi,
The apps that you have purchased could install up to 5 PC. If you no longer use a PC that you've installed apps on, you can remove it from your account. You'll also need to remove a PC from your account if you've already used your account to install apps
on the maximum number of PCs allowed.
We could follow these steps:
1. On the Start screen, tap or click Store to open the Windows Store.
2. Swipe down from the top edge of the screen, and then tap Your account. (If you're using a mouse, right-click, and then click Your account.)
3. Tap or click Your account.
4. Under Your PCs, tap or click Remove next to the PC you want to remove from your account.
Note:If you remove a PC, but it has been less than five days since you first used your account on that PC, you'll need to wait until the five days are over before you can replace that PC with a different one.
