Safe to delete "C:\WINDOWS\SoftwareDistribution\Download"
Solution 1
After you have installed all the pending updates, it is safe to delete all the files and folder under C:\WINDOWS\SoftwareDistribution\Download\
As @Zab said, stop the Update Service while you clean up the folder
- Enter
net stop wuauserv
into an elevated command prompt - Manually clean up
C:\WINDOWS\SoftwareDistribution\Download\
- Enter
net start wuauserv
into an elevated command prompt
As soon as the service starts again, some folders will be re-created. This is ok
Solution 2
You should stop "automatic updates" and "windows update" services, then you can delete all downloaded/(and already installed) updates
You can also clean the database folder nearby to "reset" windows update.
Harry reports problem with people who deleted the directories, as opposed to people who deleted files in directory.
Solution 3
If I were you I'd run the Microsoft Disk Cleanup wizard and see if it proposes deleting this directory.
If it doesn't do that, then I wouldn't touch it.

One of our Windows 2003 servers has a fairly small C-partition, which is approaching full. I've had a quick look round using Disktective as to where the space has gone, and a fair bit of it seems to be taken up with
C:\WINDOWS\SoftwareDistribution\Download
I think this folder is used as a temporary storage for Windows Update, but as all the pending Windows updates have now been installed, is it OK to delete the contents of this folder?

harrymc over 14 yearsSome people reported problems with Windows Update after deleting these files, while others didn't. It depends apparently on what you do.
