Hi. After resetting the registry settings for folders (http://support.microsoft.com/kb/813711/en-us), that is removing more than 5000 keys of folder settings, and limiting the number of folders to remember to 2000, and compacting the registry, my UsrClass.dat hive could compact from 9.0 MB to 1.5 MB (Compression: 82.64%), but RegCompact says:
Error: Too large compression! Skipping hive for safety...
Too bad, is there a way to force the process? I hope so...
