Windows Update does not know if or when those files will be available to use, so your system requires a reboot to avoid any conflicts.

I received a call from a customer today who was suddenly unable to print to Epson Dot Matrix printers, after a LOT of troubleshooting I figured out that this is due to a Windows update.

Printers I can confirm that are not working after the updates are: There may be other updates which I am not aware of yet.

Don’t do this unless you know exactly what you’re doing and why, it’s truly only an option for advanced users, network administrators, and sysadmins who need to manage devices on their own without the constant update reminders.

– Really the best thing to do is just to install the software updates if you don’t mind doing so. For example, I’m traveling, and I don’t have the time to deal with a software update, the necessary backups, and potential restores from an update gone awry.

To get your printers working again, the quickest way is to remove the offending update.

As you might not be sure which update you have installed.* This deletes the available i OS update which stops the i OS update from popping up every day, however, the moment you’re on a sustained wi-fi connection for a while the i OS update will download itself again automatically and start sending pop-ups to install it again.Don’t worry, you won’t lose the ability to install the i OS update, you can download it again yourself by going to Settings Now that the update has been removed from the i OS device, you’ll want to avoid wi-fi, otherwise the update will just download itself at the next chance it gets.The quickest way is to run the following commands in an elevated command prompt:wusa /uninstall /kb:4048952 /quiet /warnrestart wusa /uninstall /kb:4048953 /quiet /warnrestart wusa /uninstall /kb:4048954 /quiet /warnrestart wusa /uninstall /kb:4048955 /quiet /warnrestart wusa /uninstall /kb:4048957 /quiet /warnrestart wusa /uninstall /kb:4048958 /quiet /warnrestart Until Microsoft release an updated security patch you can temporarily block the patch using this tool from Microsoft: Microsoft Patch Blocker Or if you are using WSUS then you can block the patch from there.This is really a difficult problem to resolve if you don’t realise that the problem is being caused by an update, because you would’t expect an old Dot Matrix printer that has been working fine for years to be impacted by a Microsoft Security Roll-up.This is a rather dramatic approach and can lead to many unintended issues, plus it will stop the ability to download any software update from Apple at all entirely for all devices through the network until it’s reversed.
