Clearing IE temp files don't erase CRL history. How can this be purged?

Question

Even after I purge all my Internet temporary files, I still see information when I type

 certutil -urlcache

How do I purge this information?

Answer 1

The information is stored here in Windows 2008 and R2 (Vista and Win7)

Per User
C:\Users\username\AppData\LocalLow\ Microsoft\CryptnetUrlCache

Per Computer
C:\Windows\System32\config\ systemprofile\AppData\LocalLow\ Microsoft\CryptnetUrlCache

To delete the cached entries run the following command:

certutil -urlcache * delete
