Here we show you how to fix the “Service Registration is Missing or Corrupt” error in Windows 10. This is one of the fairly common Windows errors, but one that Windows Update troubleshooter cannot rectify. It’s up to you to fix it yourself. Here are some ways of doing that – but first, what exactly is this error and why does it appear?
The error notification is given while updating the Windows OS. Every now and again, Microsoft issues Updates for Windows, designed to improve security, performance and other aspects of the operating system. These updates are usually made automatically on most PCs and laptops, but sometimes your system may not identify and install them.
That’s when you may get the message that the service registration is missing or corrupt error in Windows 10 – and also in Windows 7. If you are running Windows 7, you may get the message that ‘Windows 7 Service Registration is Missing or Corrupt.’ For Windows 7, the solutions are much the same as Windows 10 – so also follow the advice below if you have a Windows 7 Service Registration is Missing or Corrupt Error.

The various symptoms are as follows:
- Windows will not update, rather it will get stuck at a particular percentage.

These are the most common symptoms associated with this error, so the experience may be a little different, for you. This error can also adversely affect system performance and prohibit you from using certain Windows features.
Windows offer an update troubleshooter. You can also get a version from the Windows App Store. These will resolve most problems you may come across, but not always.

Method 1. Disable Any Antivirus Software You Are Running
Sometimes the problem can be caused by antivirus applications. Before going further it may be wise to check this first. Turn it off and then see if the problem persists. If it does then check that any Windows update related services are running OK. Don’t forget to turn the antivirus program back on!
Method 2. Use Windows Troubleshooter
Windows comes with a built-in troubleshooter, yet few people resort to it if they get problems. Like our #1 option it’s a fairly simple thing to do, and could solve the problem immediately. To use this method, you must first start your computer with full admin rights.

Method 5. Repair Windows 10 with Windows 10 ISO
Perhaps you need to repair your Windows 10 installation using Windows 10 ISO. To do that use the following steps:

Method 6. Run Windows Update Commands
Running the Windows update commands can often resolve the Windows 10 service registration is missing or corrupt error. Here is how to do that:
- Open the Command Prompt as Administrator (Command Prompt (Admin)).
- Now run the following ten commands one after another. To do that, enter the command and hit Enter, and once each has executed, type in the other and so on:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
Now check if you are still getting the same error message. If so, then carry on to Method 5.
Method 7: Disable Windows Firewall
Sometimes the Windows Firewall can be causing the Windows to update service registration is missing or corrupt error.

Check if this resolves the problem. Once the problem has been resolved, then you can switch the Windows Firewall back on.
Method 8: ThresholdOptedIn Registry Edit
Our final method is simple to carry out and often works well. It involves the deletion of a registry key. We put this last because you must be careful when accessing your registry. If you follow these steps exactly then you should be OK. People have used it with success.
- Boot up your computer with full admin rights.
- Press the Windows key + R then type in regedit into the ‘Open’ window and click OK.
- The Registry Editor will now load up. Navigate along this path:
- Now find and delete the ThresholdOptedIn REG_DWORD value. Do this by right-clicking on it and selecting Delete.
In another case, it is possible that Applicability key doesn’t have any value other than the default value. In this case, follow the method listed below to add some keys so our error message goes away.
- Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability.
- Right-click in the empty space and select New > String.
- Rename the string to BranchName. Double click the string and type the value fbl_impressive in the Value data box. Save Changes.
- Now, create a string just as we did above and rename it to Ring. Set the Value data to low. Click Ok.
- Now, reboot and check if you still get the error. One of the above solutions will likely solve your problem if your windows update service registration is missing or corrupt.
There’s also a workaround in case changes to the registry don’t work.
- Navigate to the same path as we did above.
- Double click the Ring string we created and change its value from “low” to “WIF”.
- Now create a new string ThresholdRiskLevel” and set the Value data to “low”. Press Ok to save changes.
- Exit Registry Editor and restart your computer to save all the changes.
