What is ‘SpeechRuntime.exe’? How to Disable / Fix it?

SpeechRuntime.exe is an executable file that is a part of the Microsoft Windows operating system. This executable file belongs to the Speech Runtime Executable process and is typically located in the following directory:


SpeechRuntime.exe is a critical windows component because it is related to Cortana – windows’ virtual assistant. So, it’s responsible for speech functions like “Hey Cortana”. Therefore, removing this file is not recommended.

with the path of the Registry Key as HKCR\CLSID\{…}

However, people often face different issues with this file while using a cleaning utility that leads them to think – Is this executable file harmful to the system?

Is it Harmful?

Cyber thieves often use executable files to inject malware into the system. Therefore, people are hesitant to open any unknown executable file. Similar is the case with speechruntime.exe. But there are ways of verifying its authenticity.

Checking the Authenticity via Task Manager

If the executable file is running in the background, then you can follow the following procedure:

  1. Open the ‘Task Manager’ by pressing ‘Ctrl + Alt + Delete’ or searching in the Start Menu.
  2. Now go to the ‘Processes’ tab and locate the ‘Speech Runtime Executable’.

  3. Right-click on it and choose the ‘Properties’ option.
  4. The file is authentic if the Properties dialog is displaying the following location:

  1. However, you should also check the ownership of this file by moving to the ‘Details’ tab. So, if you find the following highlighted things in the Details tab, then the file is authenticated and there is nothing to worry about.

Checking the Authenticity via File Explorer

If you can’t find the Speech Runtime Executable in the Task Manager, this means the file is not running in the background. For this, check the authenticity by using the following method:

  1. Open ‘This PC’ (if you’re on Windows-8/10 and ‘Computer’ for Windows-7) and in the address bar type the following:
Typing the Folder’s Path in Address Bar of File Explorer
  1. Now, windows should take you to a folder where you’ll find the following files:

    SpeechRuntime.exe Folder
  2. From here, you’ll open the ‘Properties’ of ‘SpeechRuntime’ by either pressing ‘Alt + Enter’ or via right-clicking and selecting the ‘Properties’ option.

    Selecting the Properties Option of SpeechRuntime
  3. The rest of the ownership authentication procedure is the same as ‘Step 5 of Method # 1’.


The file can be harmful in the following cases:

  • If you find a suspicious directory in the ‘General’ tab of the executable file’s properties.
  • If you find any other ownership in the ‘Details’ tab of the executable file’s properties.
  • If the file is using too many GPU and CPU resources. Because often .exe files containing malware are using most of the system’s resources without opening them.

Why does CCleaner Show it?

As mentioned earlier that speechruntime.exe is a windows entry, so if you’re using Windows 10, it’s recommended not to mess with the speechruntime.exe file. Because it’s necessary for the proper functioning of Accessibility options of Cortana for visually impaired users. Plus, Microsoft strictly prohibits the use of registry cleaners on windows.

Specifically talking about Windows 10, its registry entries are often changing, so registry cleaners can’t keep up with that. You can also check Microsoft’s guide regarding using Registry Cleaning utilities on Windows 10.

Even if CCleaner is marking speechruntime.exe as an issue, then it’s still not an issue. Because

  • First of all, CCleaner is a junk cleaner and not a malware cleaner. So, that means it can’t detect malware which shows that this executable file is not malware.
  • Secondly, Windows OS needs this executable file.

Plus, the officials of CCleaner don’t recommend using registry cleaner on Windows 10 unless:

  • You want to clean or locate the leftover entries of a software application that you have uninstalled.

So, it’s recommended not to mess with these files because deleting these files might lead you to reinstallation of windows. Plus, CCleaner will hopefully resolve this issue as well.
