So I am one of the many who can't do the quest blood on the ice because for some reason I can't buy the house or get the quest to start after entering and leaving 30+ times at night.

So anyways, I was going to try something else. Use the console commands to "setstage" of the quest to buy the house "Buy a house in Windhelm" and set it to "complete" and then use the console to give me the keys and books. But I was wondering, does anyone know the quest ID or how to find hte quest ID? I tried doing help windhlem 0 but I couldn't make it out which one I wanted...

I'd like to know too. I currently have some miscellaneous quest which says "Ask wilhelm about reyda" i've already finished the quest but the game didn't remove it from my quests :/

It seems harder to find the quest IDs for misc quests...

I think 'showquesttarget' shows the ID's but i don't know how to read it :S

you can try this website but i don't think you will find every quest you need but is very useful.
