Do like the new GUI.
Here are a couple of items that I have run into thus far.
1. If System Protection is not enabled on the primary drive, jv16 hangs if the User selected to have a restore point created prior to cleaning.
2. When running the System cleaner is "aggressive" mode, it finds a significant number of *.db files that it thinks are Unneeded Temp files that should be deleted. This breaks several programs that use/store important info as .db files. For example, Cyberlink's PowerDVD 19 stores its playlists as .db files that jv16 detect as unneeded in aggressive mode. I recommended that jv16 white list *.db files.
3. Registry Compactor appears to non-existent in the new version.
4. I also very pleased that the program has been trimmed down as for as the number of features and tools...many of which 99% of the clients never or very rarely used. JMO
