Fix UNEXPECTED STORE EXCEPTION in Windows 10

What is Webguard?

Developed by Interesting Solutions, Webguard is a tool supposedly used for tracking those online who’ve developed a habit of tracking you. The application would provide logical analysis into a user’s website history, providing insight on what websites you’ve visited and also how persons are able to track your every move while browsing. While Webguard is unable to dispose of who specifically is tracking your computer usage, they’re able to determine what computer installed tracking codes or cookies on your computer system. In this case, it’s then left up to the user’s discretion to determine who they want to allow or block from tracking their online use.  Overall, this application allows the user some measure of freedom and control over their online experience. Like any other application, however, which has landed themselves a spot on Virus Total, Web guard has hidden agendas. At a distance, Webguard installs a service for Windows but later distributes advertisements. Technical details about Webguard include:

Product Version: 1.0.0.0 Original File Name: crss.exe Entry Point:  0x000C5AAE

Assessment of Webguard Potentially Unwanted Program

While Webguard claims to track your computer usage, information reported by the application isn’t sufficient for the common computer user. This brings us back to the ulterior motive or principal objective of developing Webguard – to advertise and generate revenue from clicks made by users on Ads displayed on Internet Browsers – namely Chrome, Internet Explorer and Firefox. Why should a computer user remove Webguard? Simply, it compromises one's Internet privacy and security and it keeps abreast of your Internet history. If you’re online for an extended period, you’ll see what Webguard does. While the publishers behind the application did not alert users to the use of web beacons, cookies for tracking, and other related tracking technology, that’s not why Webguard is considered unwanted. The program is potentially unwanted because of the unpredictable advertisements it displays. Not all sites are trusted and so it’s difficult to determine, in some cases, what websites are legit for business.

Remove Webguard with Spyhunter

In most cases, at least from what I’ve seen, Webguard is installed as a single application. After it was installed for this assessment, it could be found in ‘All Programs”. This meant that one could manually delete the application from their computer system (see manual steps below). However, is that really sufficient to completely rid your PC of Webguard’s blueprints? While you might opt to remove Webguard manually – maybe because it’s more economical – an automated process is able to completely eradicate hidden threats from Webguard. In comparison to manually removing Webguard, Spyhunter penetrates your computer system for all infections. In most cases, nasty threats are unable to be removed manually. Additionally, Spyhunter not only removes installed threats, but it detects incoming ones – hence, acting as a preventative tool. Furthermore, Spyhunter detects cookies placed on your computer by Webguard. These are all undetectable threats and so an automated tool, as Spyhunter, should be used to remove Spyhunter effectively from your computer.

Manual Steps for Removal of Webguard

I found this removal pretty simple. Depending on your Operating System, there will be slight discrepancies in the manual removal steps. Using the Windows 8 (8.1) OS on your computer:

• Step 1: Locate the CONTROL PANEL on your computer using the SEARCH option.
• Step 2: Once the search box appears , input 'CONTROL PANEL'.
• Step 3: The Control Panel option will then appear. From the menu, choose the "Programs" option.
• Step 4: Another menu will appear. Select "All Programs and Features".
• Step 5: From the 'Programs list', search for the Webguard application.
• Step 6: Right-click on Webguard when it's found.
• Step 7:  Choose the "Uninstall" option.
• Step 8:  Follow the uninstall wizard instructions until the Webguard application is fully removed.

When you upgrade your Windows 7 or Windows 8.1 system to Windows 10, you’ll undergo a phase called Out of Box Experience, or simply OOBE. This phase is intended to allow users to customize their Windows 10 experience, which includes defining personal settings, creating user accounts, and more. Some users reported having issues when creating their user account during the Out of Box Experience (OOBE) on Windows 10 upgrade. Some also reported issues about non-responsive behavior (Welcome Back) page.

Solution

Error Causes

Unfortunately, there’s no known cause for this error. However, some users reported that this occurs when:

• There’s a problem with the ISO or CD used to install Windows 10
• There’s hardware malfunctioning on the computer

Further Information and Manual Repair

Your Windows 10 upgrade will not be successful if you’re not able to create a user account or finish the Out of the Box (OOBE) phase of the installation. Here are some methods that will help you fix this manually.

Method 1 – Wait and retry

Some users reported that waiting for about an hour and retrying the process again will solve this problem. It’s also recommended that you keep your computer in a ventilated place while you wait to retry the process.

Method 2 – Load default user manually

This method has 2 requirements in order to work.

1. You need to be upgrading from a previous Windows version, and
2. Your Windows was originally configured to automatically boot to desktop

If you meet these two requirements, you can solve the error by following the steps below:

1. Hold CTRL+ESC keys. Windows should load the default user after doing this step.
2. Press the Windows key + X. Then, click the Computer Management icon
3. Choose “Local Users and Groups”
4. Double click on Users
5. Right-click on the right pane, and then choose “New User”
6. Create a new user account and password

Method 3 – Power down your laptop

This method only applies if you’re a laptop user.

1. Power down your laptop
2. Remove the battery of your laptop
3. Wait for about 10 minutes
4. Connect your laptop using direct current
5. Turn on your laptop again
6. Create a new user account and log in

Method 4 – Create a local account if you’re trying to set up a Microsoft account

Instead of connecting to a Microsoft Account after the set-up, you might want to try creating a local account. To do this, follow the steps below:

1. Power down your computer if you are to set up a Local Account.
2. Disconnect your computer from the Internet, either Wired or Wireless
3. Unplug your computer, and wait for about 10 minutes.
4. Reconnect your computer and start Windows. Do NOT connect to the Internet and make sure you’re disconnected to any devices you don’t need.
5. Try creating a user account again

 If the steps above don’t work, you might want to try Startup repair.

Method 5 – Boot your computer from Windows 10 media

In order to do this step, you need to have official Windows 10 ISO files.

1. Go to the “Install Now” screen
2. Choose Repair your computer
3. Click Advanced Options
4. Click Safe Mode

After doing the steps above, there’s a chance you get an error message that says “installation cannot be completed in safe mode”. When you see this, just press Shift+F10. This will execute and open the command prompt of your computer.

 From the command prompt, you can try and create a new user account.

 For example, net user Username Password /add

 The username here should be replaced with the account name you want to add, and the Password here should be replaced with the password you want to use for the account.

 After replacing the username and password on the text, press the Enter button on your keyboard. You’ll know if the command is successful once you see the message, “The command completed successfully.”

You can now close the command prompt. Restart your computer and try to log in using the account you just created.

Method 6 – Use a powerful automated software

If all the above methods still don’t work, it might be best to try automated software to help you fix this problem.

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.

Error code 0x800ccc0f - What is it?

Error code 0x800ccc0f is an error that occurs when users attempt to send/receive emails in Outlook or Outlook Express. Though information regarding the error is limited and sometimes difficult to decipher to those unfamiliar with error code issues, the following are possible symptoms users can expect when this error occurs:

• Unexpected termination of the connection
• Inability to access email messages sent to one’s account
• Inability to send email messages

Solution

Error Causes

Errors in Outlook or Outlook Express may occur due to a multiplicity of reasons. It may be due to a problem with your network connection or the server. You may also encounter this problem after an extended period of inactivity.

Since the error could be due to one of many issues, several solutions are recommended. However, note that these suggestions require you to make changes that come with various risks. Be sure to implement these instructions correctly to avoid causing more problems to occur.

If you are not confident that you will be able to successfully implement the solutions below, get help from a certified Windows technician or IT professional.

Further Information and Manual Repair

As with other error codes, manual procedures are available which users can take to correct the problem. To implement manual repair, follow the methods suggested below:

Method one: Troubleshoot your Internet Connection

Since error code 0x800ccc0f may manifest itself due to an issue with your network, you can seek to rectify the problem by first checking your connection. To do this, open an Internet browser. Type a valid web address in the address bar and click Enter.

If you are unable to access the website, you may then seek to fix the Internet connectivity issue by using Microsoft Automated Troubleshooting Services. These free tools are available for download on Microsoft’s website.

Not only can these tools fix your Windows Firewall – if this is the cause of your connectivity issues. These automated troubleshooting tools can also resolve other issues related to your Internet browser or network.

However, if after downloading and running these tools error code 0x800ccc0f still persists in Outlook or Outlook Express, implement the solution below.

Method two: Verify your Network Connection

Verifying your network connection is another way you can resolve your Outlook issues, i.e. once the issue is in fact a network-based problem.

To verify your network connection, make sure your computer’s network devices are turned on and fully functioning. Also ensure that the cables that connect your computer to a network are secure. You may also contact your Internet Service Provider (ISP) to verify your connection.

If there is no issue with your network and error code 0x800ccc0f persists, you will need to implement method three.

Method three: Check your Firewall or Router Settings

Problems with sending or receiving email messages based on the 0x800ccc0f error code could also be due to configuration issues for individuals who connect using a router. If this is a misconfiguration issue, you may be able to resolve the problem by bypassing the router and connecting through your modem.

Before doing this, however, be sure to check if your firewall is turned on as connecting directly can leave your machine vulnerable. Prevent attacks by checking your Windows Firewall setting. After making adjustments where necessary to ensure the firewall is turned on, test your connectivity to ensure you can access a connection. Also, check Outlook to see whether the error message has been resolved. If the error persists, consider the next solution.

Method four: Disable Third-party Security Apps

Third-party apps like anti-virus software can sometimes cause interference, leading to errors. For this reason, check if the antivirus on your device is the source of the issue. Start by disabling the antivirus software. You may also turn off the software’s email scanning feature to verify whether or not that is the cause of the error.

Note that disabling your antivirus is only a temporary solution as it is not recommended that you use your computer without such protection in place. Consider replacing your antivirus or uninstalling and reinstalling for a permanent fix if indeed your issue with error code 0x800ccc0f was caused by interference from third-party apps.

Method five: Automated Tool

Also, consider downloading a powerful automated tool to protect your machine from possible errors in the future.
