Hi Gill, I never had any issues with this. This registry key is just a list hot fixes that are applied. Deleting this key will tell the system the particular hot fix is not installed only WHEN YOU DO A SCAN FOR AUTOMATIC UPDATES or WHEN YOU REAPPLY THE FIX. But the installed hot fix files are not deleted from the system. This is a workaround to force reapply a hot fix, not to remove an installed hot fix. HTH Regards, Raj ________________________________ From: Sarbjit Singh Gill [mailto:ssgill@xxxxxxxxxxxxxxxxxxxx] Sent: Thursday, November 04, 2004 10:26 AM To: [ExchangeList] Subject: [exchangelist] RE: Exchange Hotfix questions... http://www.MSExchange.org/ Is that supported, i mean hotfix removal via registry deletion ? You never know what else key gets used. Backup the registry before you try this.

This might help because the hot fix looks at this location to decide if it is already applied.

One of the steps included removing Exchange from the system (Following KB article 259158). To make a long story short, this KB article never mentions that you should remove all Hotfixes prior to following the steps. Now I have a functioning e-mail server after re-installing, but several features of OWA are not working correctly. These issues are resolved by installing Hotfixes. Unfortunately, each time I try to install the hotfix, a warning appears stating that the hotfix is already installed on the server. However, when I go to Add\Remove programs and select to remove the hotfix, it errors out. Does anyone know how to manually remove a hotfix so that it can be re-installed?
