Hi lordpuffer,

Personally I do not recommend this type of additional un-install programs, Yes, iI agree that the standard un-install provided by applications can be a little too conservative in removing everything. Unfortunately these additional programs tend to be a little too severe and often cause future problems.

What I do is after an un-install is remove any remnant folders and then run Ccleaner to clear the remnant registry entries, (always do a registry backup before the registry is pruned)

CCleaner - Download

Hope this helps
