Windows users will periodically run into situations where a Windows Update either slows or completely removes their ability to connect to the Internet. This problem is usually due to some component of the updated operating system not functioning well with older drivers, though sometimes Windows Updates have been known to break things for no reason. In the past, Microsoft has even recalled some updates. Whatever the reason, if you know that your machine was working well before the Windows Update, the best way to restore functionality is often to remove that Windows Update. There are a few ways to do this.
First, you should check the Device Manager and make sure it’s not a simple error. To do that, right-click Start, click Device Manager, then double-click Network Adapters and look for your network adapter, be it a wireless adapter or an Ethernet adapter. If you find your network adapter, and it has a Code 10 error on it, then click here for a guide to manually install a driver for the device. If that’s not the issue, or if that doesn’t fix it, read on.
Try System Restore First
System restore is often the fastest, easiest way to get your system back in working order, when it’s available, and when it works. Luckily, if it doesn’t work, it won’t do anything at all. Here are the steps:
- Temporarily uninstall any third party antivirus application as these will almost universally prevent System Restore from restoring correctly, resulting in an error.
- Click Start
- Type system restore and click Create a Restore Point (don’t worry, you’re not doing that, that’s just what comes up)
- Click the System Restore button.
- Check the “Recommended restore” option to make sure the date is very close to when the Windows Update happened, but still before it happened. If so, click Next. If not, you can click “Choose a different restore point,” but those will usually be earlier dates if any.
- There may be another confirmation prompt or two, depending on your build of Windows, but after that, System Restore should do its thing. This process can take a while, so be patient.
Uninstall The Windows Update
- If the System Restore doesn’t work or isn’t available, you will need to uninstall the Windows Update. Uninstalling Windows Updates works surprisingly well and generally does not have many drawbacks, though making a back-up is recommended. After you make your backup, you will want to set a System Restore point, as they are much faster and easier to use than restoring a backup, if necessary. Creating a System Restore point is similar to using one:
- Click Start
- Type system restore and click Create a Restore Point
- Check to make sure your system disk, probably (C:), has Protection “On.” If not, click it Configure, and click Turn on System Protection, move the slider until it’s using around 5% – 10%, then click Apply > OK.
- Click Create
- Name it something you’ll remember, like “Uninstalling Windows Updates.” It will append the date, so you’ll also have that information. Click Create and give it some time to finish.
- Once finished, close the “System Properties” window that opened when you searched for System Restore.
- Now to uninstall that update. These are hidden in your Windows Update History. Click Start, and type Windows Update.
- Click Windows Update Settings
- Click View Update History
- Click Uninstall Updates
- Click the Installed On column header to sort by the Installed On date until the newest updates are at the top.
- This part is important. Even though you sorted by the newest updates, you’re probably still not looking at updates for Microsoft Windows. Instead, you’re probably looking at updates for Microsoft Office, or Microsoft Visual C++, or possibly some other Microsoft product that you didn’t even know you had. You can tell because, just under “Name,” it will list the name of the application with no other information to its right. Scroll until you find Microsoft Windows, and you will have found the updates that we’re looking for.
- You will want to uninstall any update that took place between now and when your machine last worked correctly. To do that, click the update, and click Uninstall, which will hopefully appear beside “Organize” at the top of the columns. If the option to uninstall does not appear, this means that you cannot uninstall that update and keep your operating system intact. The same goes for updates that are not listed.
- If you are unable to uninstall the update, you may have to resort to restoring a backup or, if that’s not possible, resetting Windows. Click here for Microsoft’s article on resetting Windows.
