If your Windows 10 computer stops working
after you’ve installed a program or an update, you probably wish it had a big ‘Undo’
button. Well it does, and it’s called System Restore,
and in this video I’m going to show you how to use it. This is Dave’s Tech Rescue, where I solve
your problems with computers, Internet and technology.
If you have a question you’d like to ask me, leave it in the comments below and I’ll

my next video, where I might be answering your question. Today’s question: My computer has stopped working. It was fine
before Windows installed the latest updates. How do I get it working again? Well, you might not realise it, but Windows
is always making plans in case something goes wrong. Every time you install a program, Windows
takes a snapshot of your computer’s settings. If the program causes serious problems, like
the computer turns off for no reason or you get strange error messages, then you should
be able to turn the clock back to when the snapshot was made, and everything should work
again. It’s called System Restore, and it protects
you whenever you install updates, programs, or new hardware – like if you add a printer. You don’t have to worry about losing any
documents or other personal files, because System Restore doesn’t affect these. However
when your computer starts having problems like this, it’s a good time to think about
making a backup if you don’t already have one. There are a couple of ways to access System
Restore, depending on whether or not you can start your computer. I’m going to show you
both ways, and I’m also going to show you how you can check that your computer is being
protected by System Restore, because never know when you might need it. Before you start, you should remove anything
that you’ve plugged in recently. If you’ve installed new hardware, like a new graphics
card, then you should shut down the computer, unplug it from the mains power supply, and
remove the new hardware. IF YOU CAN START YOUR COMPUTER If Windows starts up, but you’re getting
strange error messages or other symptoms, then you can access System Restore from within
Windows. First though, if you know you’ve installed
a program recently, it’s a good idea to remove that program and see if it makes a
difference. Let’s take a quick look at how to remove
a program. Make sure you close and save anything you
have open. Then click on the Start Menu, and click on
Settings, which is the gear symbol. Then go into Apps. You should see a list of all the apps on your
computer. You can put this list in date order – click Sort By, and select Installation Date. The newest apps should be at the top. If you
suspect one of these caused your problem, you can select it, and click Uninstall. I’m just showing you this as an example, I
don’t have a problem with this app. Then you should restart the computer, and
see if the problem has gone. If you still have the same issue, then you
should open System Restore. Click on the Start Menu or Cortana, and type
Recovery. When you see Recovery, click on it. Its icon has a blue screen with a clock
and a green arrow. Then click on Open System Restore. System Restore should appear, and it shows
you when the most recent program or update was installed. It’s a good idea to start
with this as a restore point, but I’m going to show you how to choose other restore points. So click on the other option, Choose a different
restore point, and click Next. You’ll see the most recent Restore Point
again, and you can see if there are more restore points by ticking this box below. It looks
like my computer has made a few restore points over the last few weeks. This is good to know, because if the most
recent point doesn’t help, there are other things we can try. But for now, I’m going to select the most
recent restore point, and click Next. Now pay attention to the notices below, and
if you’re happy to go on, click Finish. Then read this message, and if you’re happy
to proceed, click Next. Then your computer will go to a screen like
this. You’ll need to wait a while for the System Restore – It took about 25 minutes
on my computer. When it’s finished, you get a notice telling
you whether the System Restore was successful or not. You can click Close on this. If the Restore failed for some reason, you
can open System Restore again and choose a different Restore Point. Click on Choose a Different Restore Point,
and click Next. And then Show more Restore points. Then you just need to try a different Restore
point. You can work through them all until you find one that works. Something I’ve found is that System Restore
can sometimes tell you that it’s failed, but the problem seems to be fixed anyway.
So if that happens, I think you can assume that it has worked. After you’ve done a System Restore like this,
you can normally work out what caused the problem in the first place, from the label
of the System Restore point that worked. Sometimes you can just install the software
or update again and the second time round it just works, but if you get the same problem
the second time round, you’ll need to roll it back again with System Restore, and then
you’ll need to work out if there is a problem with what you’re trying to install. So, now we’ve covered a basic System Restore,
we can now look at what we need to do if the computer won’t start up. IF YOU CAN’T START YOUR COMPUTER If your computer won’t start up, you’ll
find that it goes into Automatic Repair, where it tries to diagnose the fault and fix it. If Automatic Repair can’t fix the problem,
you’ll see this screen – Your PC did not start correctly. So, now you’ll need to try System Restore. You can get to System Restore by clicking
on Advanced Options. Then click on Troubleshoot, And Advanced options. Now click on System Restore. Click on your user name and enter your password.
If one of your user accounts is an administrator, you should sign in as that user. When System Restore starts, click Next. Now you’re on same screen we saw in the
first part of this video. Choose a Restore point from the list, and follow the instructions
on the screen to restore from it. Once the System Restore has finished, you
should be able to start your computer as normal. While we’re looking at System Restore, it’s
worth knowing how to check your computer is being protected by System Restore. Open file Explorer. Click on This PC, then right click on it,
and click Properties. Click System Protection. Look for the Protection Settings box, and
make sure protection is turned on for your main hard drive. If it isn’t, click Configure. Then select Turn on System Protection. Then click OK. Then you can close all these windows. Now you can be confident that your computer
is making Restore Points whenever it needs to. Did System Restore work for you? Please let
