Q: Is it true the number of devices I can install my Windows Store applications on has increased?
A: When the Windows Store applications were first launched, an application could be installed on up to five devices, which covers most user scenarios. However, as times have changed, the five-device limit is becoming a blocker for some people. So Microsoft has raised the number from five to 81 as documented at the Windows App Builder blog. It's hard to imagine one user needing to install applications on more than 81 machines!
