Hi, this is Wayne again with a topic “What If You Turn Off Your PC During An Update?”.
Warning don’t turn off your computer during this update, as often as you’ve seen this message, you’ve probably wondered: well what exactly would happen if i turned off the computer or worse yet lost power during an update and what, if windows, update, gets stuck and just never completes Is it safe to restart the pc, or are you doomed to have something go wrong? So here’s the deal back when windows vista first came out. Microsoft was trying to find a way to make the update process a little more robust, with more and more people getting updates delivered over the internet. So they introduced a mechanism called component based servicing cbs, then no, not that one does a couple of things differently to ensure that updates are installed correctly. First, it checks to make sure that all required files are present before starting installation, and this is perhaps more relevant for what we’re discussing today.
It marks an update as complete after it’s installed. Cbs is part of the underlying architecture of windows update. So if there’s a power loss or you just unplug your computer, during an update as part of some kind of masochistic experiment, it’ll kick back in once you boot back into windows and see that an update wasn’t marked as complete.
Now i won’t know why the update wasn’t completed, but it also doesn’t have to instead cbs just rolls back whatever changes the updater made and restores whatever the previous state was before you started the install allowing you to try again later without damaging anything on your pc. So those please do not turn off your computer messages. Don’T always mean that you’re at risk of an imminent catastrophe. If you don’t follow the instructions with a caveat, cbs obviously requires critical files that help run windows itself in order for it to operate. So while cbs might work perfectly, if a shutdown occurs, while windows is updating the gui or installing some non-critical feature you still might be in for a world of trouble. If the power loss happens, while core windows components are being updated and unfortunately, you’ve got no way of knowing when that’s happening, because windows doesn’t tell you, the result can be anything from certain aspects of windows not functioning correctly to windows, refusing to boot at all.
Instead, giving you a blue screen of death or simply a blank display when you try to start up the system uh-oh, but if this happens, try not to panic even the most disastrous, failed updates shouldn’t touch the personal data on the drive. So if your pc won’t boot into windows, you can use a windows. Installation usb drive that you can easily create on another system and boot into that under troubleshoot.
Then you can use startup repair to fix the damaged windows files that are giving you the issue. Then, if that doesn’t work for some reason, you can always open up command prompt from that same usb type. Notepad.Exe to open notepad then use the open command in notepad to bring up a file explorer window. That will allow you to copy any files you need to another storage device, or this is the much easier way you can just remove. The drive from your computer entirely connect it as a secondary drive to a different pc and copy all your files.
That way, but okay, what if you feel like you have to restart during the update process, because windows update is simply not moving and is stuck at a certain percentage for a very long time like even for hours. This can happen for any number of reasons, but if it’s been stuck for an excessive period – and it looks like your drive – isn’t busy anymore, like the leds – not blinkity blinking, it probably won’t hurt anything to restart the system and take another crack at it once it Comes up, you can use a troubleshooter, that’s built into windows, to clear the windows, update cache, which can often fix problems with windows, update just type troubleshoot windows, update into the windows, 10 search bar to find it so bottom line. Then try not to panic. If your update gets interrupted far worse, things could happen to your data like having linus handle it.
