You can use your Microsoft account to sign in to the Windows Store and install your apps on different PCs.
Sign in to the PC you want to install your apps on using your Microsoft account.
On the Start screen, tap or click Store to open the Windows Store.
Swipe down from the top edge of the screen, and then tap Your apps. (If you're using a mouse, right-click, and then click Your apps.)
Tap or click the apps you want to install, and then tap or click Install.
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.
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.)
Tap or click Your account.
Under Your PCs, tap or click Remove next to the PC you want to remove from your account.
You can remove a PC from your account when you're signed in to the Store on any PC.
After you've removed a PC from your account, you won't be able to use the apps that were installed from the Store on that PC.
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.
