Under normal circumstances, even with a "hard shutdown" (that is, holding in the power button until the power cuts off, creating the equivalent situation that a power outage would) Windows tends to recover gracefully.
It is really impossible to state anything definitively without knowing exactly what was occurring before the shutdown and exactly how the shutdown was caused. Even if those things are known it's not 100% predictable.
Your best bet is just to fire it up and see what happens. Don't be in any rush if Windows goes into a repair state, as it can take a while.
