Today I wanted to talk a small bug I seen from some Windows 10 with UWF enabled.
The error I seen was 0x000003EB and 0x000006BA
The error is pretty generic, but the system greyed all the printers in the Windows 10’s list, and you can’t connect to other printers from the server, nor add them by GPP or by deploying them.
In the past I used to use a Microsoft KB .exe to fix and erase all the spooler, by a hard reset, but the utility was removed from the website, as such to find the exact cause or to reset the error I suggest to get that small Kyocera’s utility (KM Deleter) now;
The error in my case seemed to come from UWF, as I unlocked the spooler folder for read and write, but I miss some registry key. As seen there;
As you can see no file or driver were present, but the registry were, so it blocked the Windows 10 to reconnect to those printers.
In my case I allowed more exceptions in the UWF, but you can see those two errors can happen if the driver is badly setupped, or missing necessary files.
