I setup various physical laser printers and pdf printers on my 64bit Win 7 Pro system.
They work fine for a long time.
Then I decided to try out Wise Registry Cleaner v8.82 with Default scan.
Since I cannot validate each found issue I had to trust Wise and fixed all problems.
After a while (and a reboot) I had to use one of the printers mentioned above.
Much to my surprise they did not work any more.
Further investigations show that when I go to
ControlPanel--->Devices and printers
select one of the listed printers, right click and selected "Printer Properties", go to to tab "Ports" then the list
is completely empty - for ALL printers.
Have a look at the attached snapshot
Even worse: I found no solution to re-create them
The only reason for that can be a false wiping from Wise Registry Cleaner of ActiveX/COM components or other registry entries (possibly
or a branch below)
This is very, very annoying.
Why does Wise Registry Cleaner think it must remove these branches?
Devs should fix this urgently.
