YESSS : I finally found that KB5001649, to address the printing problem of my users : blocked on photo prints since a week...
So I went to install it on a computer to give a try ... but the OS version is 21H1 (ie v 19043.867 ) ! So it refused to install.
Am I the sole with this problem ?
Does someone have the solution ?
Or is this KB to be updated soon ?
printf('Have I missed something ?');
