If you increase the window unit or size you potentially increase the number of SSTable candidates for compaction inside each window, which is why you would see more compactions. If you decrease the window you shouldn't see any new compactions kicked off, however be aware that you will have SSTables covering multiple windows, so until a full cycle of your TTL passes your read queries won't benefit from the smaller window size.
