hi,
I have some old laptops running Win 10 Pro 32 bit. The machines with 1703 have no problems updating the Printer List from Windows Update when we need to install a legacy printer driver such as Brother HL-1450 and others. (No driver is available direct from manufacturer).
But 1709 and now 1803-RTM both time out, often within 15 seconds advising it cannot update the printer list, and to try later. This issue has existed for weeks.
I have tried running windows update troubleshooter. I also tried stopping services and deleting the Contents of the Software Distribution folder. I've also tried a completely clean install of 1709 on one laptop. Printer lists just simply refuse to update. Cumulative and other updates download and install just fine.
The only workaround I found to successfully install a legacy printer driver onto 1709/1803 machine, was to use a machine running 1703 and configure a shared printer using the desired legacy driver previously retrieved from Windows Update. Then permit the 1709 laptops to connect to the shared printer on 1703 laptop. Once the driver is installed on the 1709 laptop, I can then set up the local printer.
I've seen a few other similar posts reporting same symptoms but with no successful resolution.
