If you are running the Windows Update service but decided to stop it but you encountered an error message instead that says, “The Windows Update service could not be stopped”, read on as this post will help you fix the problem. This kind of error appears when you use the Command Prompt to stop the Windows Update service, especially if you are using cmd without admin privileges. A lot of users reported that they were not able to disable the automatic Windows Update in Windows 10 using Command Prompt. The command used to stop the Windows Update service is the “net stop wuauserv” command. However, when some users executed this command, they got the error message. So if you are one of these users that can’t stop the Windows Update Service via Command Prompt, you can try to fix that using PID as well as checking the Service dependencies. For more details, follow the given options below.

Option 1 – Try to stop the Windows Update service via PID

In case you don’t know, each running service or process has its own unique ID or PID and you can find it in the Task Manager. You can use it to stop the Windows Update service. How? Refer to these steps:

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Next, go to the Services tab and look for the service named “wuauserv” and get its PID.
• After that, type “cmd” in the Windows Start search and right-click on Command Prompt from the search results and then select the “Run as administrator” option.
• After opening Command Prompt with admin privileges, execute this command: taskkill /f /pid <PID>

Note: You need to replace “<PID>” with the PID of the “wuauserv” service. For instance, the PID is 6676, then this is how the command should be “taskkill /f /pid 6676”.

• After you execute the command, you will this message on your screen, “SUCCESS: The process with PID 6676 has been terminated” which indicates that you have stopped the Windows Update service successfully.

Option 2 – Try to check the Service dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependant service will also be affected. This could be the reason why the Windows Update service could not start.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the following services:
  • Remote Procedure Call (RPC) Service
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
• After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
• If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.

Microsoft’s initial Windows 11 hardware requirements were not really well received by users and they were not really clearly represented from the start making a lot of potential customers slowly drift away from the hype. It seems that Microsoft has acknowledged this since they have changed their tune about system hardware requirements for the upcoming Windows 11. It seems that Windows 11 will be able to be officially installed on unsupported computers but with a little inconvenience.

What is a catch?

Windows 11 will still have the same hardware requirements and if the PC meets them, that computer will be officially supported, other ones (any that can run Windows 10) that do not meet system requirements can still run Windows 11 but the system will have to be clean installed. So no upgrade option for old computer users, just a clean install. This means of course that you will need to download the ISO image and make a bootable USB in order to install it. Also since you will be doing a clean install do a backup of the hard drive since it will need to be formatted. Also, Microsoft has stated that with unofficially supported PC some driver updates might not be delivered leaving you with either older driver versions or relying on your hardware manufacturer on them. This is still not confirmed by Microsoft, just stated as an option. We will see how it goes.

Conclusion

It is very good that Microsoft has reconsidered its system requirements and will not stubbornly push its initiatives over the top requirements allowing even older computers to install new OS. I am sure over time lot of users will upgrade their hardware and drive into officially supported waters, but it is good that they will be able to use new OS on their current hardware.

In most cases, this kind of issue can be fixed when you restart your computer and go to the Windows Settings and select the “Add Bluetooth or other devices” option and then put the keyboard into pairing mode. And when the keyboard appears in the “Add a device” dialog box, just select it. On the other hand, if your Bluetooth keyboard won’t get connected to your Windows 10 computer and you encounter an error that says, “Can’t pair Bluetooth keyboard, Check the PIN and try connecting again”, then you need to check out the options provided below but before you do so, make sure that you create a System Restore point first as some of the troubleshooting options provided involves the Windows Registry.

Option 1 – Try to use the Device Pairing Wizard

This should be the last resort method, as you should not have to purchase a new Windows 7 key code if it is not necessary. If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.
