“Windows could not search for new updates” – is an all too common problem for Windows users nowadays. When encountering one of these errors, the most important thing is the error code. Why, because it determines the cause and possible solutions.

Although your Microsoft operating system needs regular updates to run smoothly, meeting these basic requirements can seem like a real challenge, especially if you are getting error messages that Windows cannot check for new updates.

However, you shouldn’t be discouraged: one thing at a time. , and today we are going to help you fix Windows Update Error 800B0001.

What Causes Error 800B0001

Error 800B0001 occurs quite frequently on Windows-based systems, and for 3 most common reasons. These are the following:

  • The Windows update component is unable to find the cryptographic service provider.
  • A catalog store file, required by Windows update has been corrupted.
  • The Windows registry has been corrupted.

Because of the high prevalence at which this error occurs, Microsoft went ahead and created a solution, in the form of a tool, which has proven to be quite efficient (though not fool-proof) at fixing this error 800b0001.

How to Fix It

As I previously mentioned, the Microsoft tool is probably your best option, but it’s not infallible, which means, it may or may not work. If it doesn’t, then there are a number of other things that can be done, all of which I have outlined below.

1. Scan Your System For Malware

First, it is important to rule out malware issues. Therefore, run a full system scan to check whether your PC is malware-infected. You can do that by using your third-party antivirus tool or the built-in Windows Defender solution.

Here is how you can use Windows Defender in Windows 7:

Start -> Type ‘Defender’ into the Search box -> Windows Defender -> Scan

Scan Your System For Malware

To do that in Windows 10, follow this way:

Start -> Settings -> Update & Security -> Windows Defender -> Open Windows Defender

You should also scan your system with a special anti-malware tool, such as Auslogics Anti-Malware, to make sure your main antivirus has not missed some particularly treacherous intruders. Teamwork matters, you know.

2. Perform A Clean Boot

It may seem surprising, but one of your programs or services might have taken against Windows Update, which means your PC is a kind of battlefield now. The point is, in a situation like this, you have to pick sides.

All things considered, we recommend you to stand by Windows update. As such, you should clean boot your Windows to figure out what item is to blame for the 800B0001 update annoyance.

To perform a clean boot, take the following steps:

  • Hit the Windows logo key and S buttons simultaneously-> Type ‘MSConfig (without quotes) -> Enter
  • General tab -> Selective startup
  • Load startup items -> clear this panel
  • Services tab -> Hide all Microsoft services -> Disable all the items
  • Save your changes and restart your machine

If the Windows update error 800B0001 is notably absent, enable your Microsoft services as well as startup items one at a time to figure out which of them is the root of the problem.

3. Run Gpedit

This process entails using the group policy editor to repair the integrity of the Windows update component. It sounds more complicated than it actually is, all you have to do is the following:

Note: This option is only available on the later versions of Windows (8/8.1/10).

  1. First, boot into your computer with administrative access.
  2. Then press + R, type gpedit.MSC and click on OK.
  3. Once the group Policy Editorloads up, navigate to the following path: Computer Configuration -> Administrative Templates -> System and then double click on Specify settings for optional component installation and component repair.

Run Gpedit

  1. Once the Specify settings for optional component installation and component repair dialog box appears, click on the Enable button, then check the box next to Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS) and click on OK.
  2. Lastly, restart your system.

4. Use The DISM Tool

If you are a Win 10 user, try running the built-in DISM (Deployment Image Servicing and Management) tool:

  • Open your Search box and type CMD into it -> Select CMD from the list
  • Right-click on it and choose to run it as an administrator -> An elevated command prompt will open
  • Provide an administrator password or your confirmation if prompted -> Allow
  • Type the ‘DISM.exe /Online /Cleanup-image /Restorehealth’ command (without quotes) -> Press Enter -> Its execution may take several minutes -> Wait for the process to finish
  • Then type the ‘SFC /scan now command (without quotes) -> Press Enter -> It may take a while for the operation to finish

Close the command prompt and open your Windows Update to see if it is OK now.

5. Use The System Update Readiness Tool

To fix Windows Update corruption in Win 7, you should download the System Update Readiness tool from the Microsoft Support website and install it on your PC. The tool will run automatically and help you install the necessary updates.

6. Fix Your Registry Issues

If resetting your Windows Update components has been to no avail, this might mean your system registry is corrupt. You can try to fix it manually, but you should bear in mind that committing even a tiny error while editing the registry can cause your system to malfunction. Besides, you may find it difficult to find out what exactly is wrong with your registry.

That is why we recommend you use special software to get the job done. For instance, Auslogics Registry Cleaner is a 100 % free tool that can fix your registry and ensure its smooth and stable performance.
