Yep there are indeed approx. 44000 vendors on the list after a clean CIS install.
You either deleted cmddata file as futuretech indicates or you selected All Vendors (you ticked the All-box) and then you deselected 30 of them and then you clicked on the Remove button (by accident) deleting 44000-30 vendors from the list. All of that can be done with just a few mouse clicks in less then a minute.
lol nope at least here on my end. Recently removed v220.127.116.1162 and installed v18.104.22.16812 from the Offline Installer and the issues I reported long ago in this topic are still happening.
Believe it or not, I’ve accomplished this strange achievement in the past with my bare hands, and also recently when installing v22.214.171.12412 I was able to manually remove one by one all unwanted vendors within a single day :o leaving only a few vendors (less than 100, certificates from big companies only).
I reinstalled CFW (ciscleanuptool_x64.exe 126.96.36.199 + CIS Offline).
I found the complete list of publishers. Good news.
It is possible to change the status of a whole set of publishers at once (select the publishers, right click “Change Vendor Rating to” and the rating of all selected publishers changes).
The pity is that the next time you install CIS, you will have to redo the job because the export/import doesn’t exist.
The size of cmddata has been divided by 2 to 98 Mb. Good news.
