How big is the Download folder in SoftwareDistribution? I usually empty this manually every few months.
You can safely delete the entire contents of the SoftwareDistribution folder, but it's quite likely that any Windows Updates you've chosen to hide will return and nee re-hiding. That's why I just delete the Downloads folder.1.2GB. Is this safe to clear?
