Steam Deck release is almost upon us and more news comes to light. The Latest officially confirmed technical detail is that the user will have access to device's BIOS and that dual booting will be officially supported. This, of course, means that you will be able to have both Proton and Windows on your device letting you play anything that you wish if the hardware is strong enough. Valve also said that you can launch OS from an SD card! This of course will save space available for games themselves, especially for entry models with less than one available. All of this information really pushes Deck into the territory of a handheld PC and not just another console and I must admit that this announcement left a smile on my face.

If you are trying to connect to the internet using a Wi-Fi, Ethernet, or a Wi-Fi connection and you suddenly encounter Error 633, then read on as this post will guide you on how you can fix this problem in your Windows 10 computer. According to users who encountered the same problem, when they try to connect to the internet, an error pops up that states, “The modem or other connecting device is either already in use or not appropriately configured”. This error is the VPN Error 633 which indicates that the modem is malfunctioning due to some broken configuration. It is possible that this broken configuration is caused by the WAN Miniport device which is associated with your preferred VPN protocol. It could also be due to the TCP port that’s required for the VPN connection to work might be used by another application. There are instances when Error 622 could occur when there are multiple internet connections set up on one device or when the communication port is exploited by another program. It could also occur when the affected modem is not bound to one specific device. Thus, any model and computer can be affected by this problem. The first and basic thing you can do to fix the VPN Error 633 is to turn off or unplug the modem your computer is using and then plug it back in to see if the problem is fixed. If not, then there are several other potential fixes you need to check out to resolve the problem. You can try the suggestions provided below and see if any of them help.

Option 1 – Run the Network Adapter Troubleshooter

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 2 – Try to explicitly reserve the TCP port

The next thing you can do to fix the error is to reserve the TCP port explicitly and to do that, follow the steps below.

• Tap the Win + R keys to pull up the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters
• After that, follow the path New > Multi-String Value on the edit menu and rename the multi-string value as “ReservedPorts” and then double click on it.
• Now in the value data of ReservedPorts, input “1723-1723” and click OK to save the changes made.
• Close the Registry Editor and restart your PC. Once your computer has restarted, check if the VPN Error 633 is fixed or not.

Option 3 – Try to use the netstat command

• In the Windows Start Search, type “cmd” and from the search results that appear, right-click on Command Prompt and then select the “Run as administrator” option.
• After opening Command Prompt as admin, type this command and hit Enter: netstat –aon
• After that, the output will be displayed and from there, look for the process ID or PID of any program that uses the TCP port 1723 on your computer.
• Next, type this next command and hit Enter: taskkill /PID PID /F
• Once the command has been executed, the concerned program will be forced to close and the TCP port 1723 will be freed up. Keep in mind that the taskkill command ends the process corresponds to the process ID number and the given command above, “/F” option is used to end the program’s process forcefully.
• Now restart your computer and after that, the concerned program should start using a TCP port other than 1723 which leaves the TCP port 1723 free for your internet device to use.

Option 4 – Remove any irrelevant internet device programs

You could also try removing any irrelevant device programs since it is possible that any of these programs could be the one that’s causing the modem to malfunction. These irrelevant programs could be an internet booster or third-party tools that comes with the modem and so on. These programs are not necessarily needed for your modem to function. Thus, if you want to fix the VPN Error 633, you can try uninstalling them and see if it fixed the error.

Option 5 – Update the Network Adapter drivers

You might also want to update the Network Adapter drivers by following these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand them.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the VPN Error 633, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly. To reinstall the network adapter driver, refer to these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

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.
