System errors can affect almost any operating system, and one of those errors is ERROR_TOO_MANY_POSTS. You can easily recognize this error by its Too many posts were made to a semaphore message, and today we’re going to show you how to fix it.

How to fix ERROR_TOO_MANY_POSTS error?

Fix – ERROR_TOO_MANY_POSTS

Solution 1 – Install the latest Windows updates

Windows 10 is a great operating system, but it has few bugs and compatibility issues. Sometimes system bugs can cause this error to appear while trying to run specific apps. To make sure that your PC is bug-free, it’s always a good idea to keep your Windows up to date. Updating process is streamlined in Windows 10 and all important updates are downloaded automatically in the background. This is great since you don’t have to worry about updating your PC. However, sometimes certain errors can occur and cause you to skip an important update.

If you don’t want to wait for Windows 10 to automatically check for updates, you can do that manually. To check for updates, do the following:

  1. Press Windows Key + I to open the Settings app.
  2. Now navigate to the Update & security section. Click on Check for updates button.

Windows will now check if your system is up to date. If any update is available, Windows will download it automatically in the background. After updating the system to the latest version, check if the error message still appears.

Solution 2 – Check your antivirus settings

In some cases your antivirus software can also be the cause for this problem. Some antivirus features can interfere with your system and prevent certain applications from running properly. To fix this problem you need to check your antivirus settings and disable the problematic feature. This isn’t a simple task since all antivirus tools are different, so if you’re not familiar with system security you might have some issues finding and disabling the problematic feature.

Solution 3 – Disable or remove your antivirus

As we already mentioned, your antivirus can also cause these types of problems to appear. If you can’t find the security feature that is causing the problem, you might want to try disabling your antivirus entirely. Keep in mind that disabling your antivirus won’t leave your system vulnerable because Windows 10 comes with Windows Defender that works as a default antivirus.

If disabling the antivirus doesn’t solve the issue, you should consider removing your antivirus software. Keep in mind that antivirus tools tend to leave certain files and registry entries behind even after you uninstall them. These files can also interfere with your system, therefore we recommend to use a dedicated removal tool. Almost all antivirus companies offer these tools for their software, so be sure to download one for your antivirus and use it to remove any leftover files.

If removing the antivirus fixes the problem, try switching to a different antivirus tool and check if the problem appears again. On the other hand, if you already have an antivirus license, you can try to install the latest version of your antivirus software or contact the antivirus manufacturer for technical support.

Solution 4 – Perform a Clean boot

Third-party applications can also cause this problem to appear, so it’s important to find and remove the problematic app. Many applications tend to start automatically with Windows, and that can cause this and other errors to appear. To find the problematic application, you need to do the following:

  1. Press Windows Key + R and enter msconfig. Press Enter or click OK.
  2. System Configuration window will appear. Go to Services tab and check Hide all Microsoft services. Now click on Disable all button.
  3. Navigate to the Startup tab and click on Open Task Manager.
  4. List of startup applications will appear. Select the first item on the list and click on Disable button. Repeat this step for all entries on the list to disable them.
  5. After disabling all startup applications, close Task Manager. Now navigate back to System Configuration window and click on Apply and OK to save changes.
  6. Restart your PC to apply changes.

After your PC restarts, you need to check if the problem still persists. If not, it’s certain that one of the startup apps or services was causing this issue. To find the problematic application you need to enable applications and services one by one or in groups. Keep in mind that you need to restart your PC after enabling each set of applications in order to apply changes.

After you find the problematic application, you can keep it disabled, update it or remove it from your PC.

Solution 5 – Keep your apps updated

We already mentioned that you need to keep Windows up to date if you want to be sure that your system is bug-free. Since third-party apps can cause this problem to appear, it’s important to keep them all up to date in order to reduce the chance for any bugs. If the problem appears while trying to run a specific application, you can try updating that app to the latest version and check if that solves the problem.

In addition to updating your apps, you can also try to reinstall the problematic application as a potential solution.

Solution 6 – Remove any recently installed applications

Third-party apps can often cause this problem, and in order to fix it, it’s recommended to remove any recently installed or updated applications. To do that, follow these simple steps:

  1. Open the Settings app.
  2. Go to Apps section.
  3. List of applications will now appear. Set Sort by to Install date. Select the application you want to remove and click the Uninstall button. Follow the instructions on the screen to remove the application.
  4. Repeat this step for several recently installed apps.

After you remove those apps, check if the problem still appears. Alternatively, you can remove applications by doing the following:

  1. Press Windows Key + S and enter control panel. Choose Control Panel from the list.
  2. When Control Panel opens, select Programs and Features.
  3. Once Programs and Features window opens, click on Installed On.
  4. To remove an application, simply double click it and follow the instructions on the screen. Repeat this step for several recently installed applications.

Both these methods are the same and both of them will remove third-party apps from your PC. Keep in mind that the first method will also allow you to see and remove Universal apps. Universal apps aren’t related to this issue, so there’s no need to remove them in order to fix the problem.

Solution 7 – Perform System Restore

Another way to fix this issue is to use System Restore. If this error started appearing recently, you might be able to fix it by restoring your system. Thanks to the System Restore feature you can restore your PC to an earlier state and revert any recent changes. Keep in mind that this process can remove any recently saved files, so if you have any important files be sure to back them up in advance. To restore your system, do the following:

  1. Press Windows Key + S and enter system restore. Choose Create a restore point from the menu.
  2. System Properties window will appear. Click on System Restore button.
  3. When System Restore window opens, select Choose a different restore point and click on Next.
  4. Check Show more restore points option and select the desired restore point. Click the Next button to proceed.
  5. Follow the instructions on the screen to complete the restoration.

Once your PC is restored, the problem should be fixed and everything should work normally.

Solution 8 – Reset Windows 10

If none of these solutions can fix the problem, you can try to reset Windows 10. This is a drastic solution and it will remove all files and applications from your system drive, so be sure to create a backup. In addition, you might need a Windows 10 installation media to complete this process. Once you have everything ready, you can reset Windows 10 by following these steps:

  1. Open the Start Menu and click on Power button. Press and hold Shift on your keyboard and choose Restart from the menu.
  2. You’ll see a list of options. Select Troubleshoot > Reset this PC > Remove everything. You might be asked to insert your installation media, so be sure to have it ready.
  3. Select your version of Windows and choose Only the drive where Windows is installed > Just remove my files.
  4. You’ll now see a list of changes that the reset will make. Click on Reset to continue.
  5. Follow the instructions on the screen to complete the process.

After you reset Windows 10, you’ll have to install all your applications and move files from backup. This solution will remove all files from your system drive, so you should use it only if other solutions can’t fix the problem.
