My HFS+ for Windows updated itself a few days ago & I noticed that it was no longer starting on login.
Autoruns showed that it starts from Task Scheduler and couldn't find c:\program files (x86)\paragon software\hfs+ for windows\hfs+ for windows.exe
Not surprising, because the HFS+ executable appears to have changed names to \hfs+ for windows by paragon software.exe
Once corrected in Task Scheduler all was well.
Naughty boys Paragon!
