Hello,
I downloaded and installed latest JV16 PowerTools 2016 Beta 4. After rebooting, and trying to use your program, I noticed a warning about BitDefender Free AntiVirus asking to put files on its whitelist. However, BitDefender Free doesn't have a whitelist, so I disabled its realtime protections and exited it.
Next, I tried to use 'Clean and SpeedUp My Computer' tool. However, the scan doesn't finish. It keeps going for hours, even after all green checkmarks are completed. I attached a screenshot showing the dialog that never ends.
Next, I tried the 'AntiSpy'. I don't know if it worked, but it asked for a reboot and I rebooted.
Next, I tried the 'Registry Compactor' tool. I don't know if it finished its job, but it asked for a reboot and delayed the boot a bit after I rebooted.
Next, I tried the 'Registry Cleaner' tool. Got the same problem that happened with 'Clean and SpeedUp My Computer' tool.
Next, I tried 'Clean and SpeedUp My Computer' tool a bit more times. And it now worked, but the registry was apparently clean, only tmp files appeared to clean. This made me suspicious.
I'll send a private message with the zipped 'Backups' download link. Thanks!
