WER folder eating up disk space on Windows Server 2008

My ASP.NET app, running on Windows Server 2008, suddenly died:

Could not load file or assembly ‘Coolite.Ext.Web’ or one of its dependencies. There is not enough space on the disk. (Exception from HRESULT: 0×80070070)

So I dug around and found that C:\ProgramData\Microsoft\Windows\WER\ReportQueue was taking up GBs upon GBs of space. A rudimentary google showed that this is a common problem and running Disk Cleanup is the answer. Unfortunately Disk Cleanup is not installed by default on Windows Server 2008; an install requires a reboot, something I didn’t want to do. So I fired up a Command Prompt window:

cd \ProgramData\Microsoft\Windows\WER\ReportQueue
del /s *.tmp.hdmp
del /s *.tmp.mdmp

So far, so good …
