In case you don’t know, Windows 10 supports installation and use of a number of removable devices which includes plug and plays mouse, keyboard, and other USB-based devices. But this could actually pose a threat to the integrity of a computer system and thus, some organizations pose a restriction in using these kinds of devices. the restriction on these devices is also useful especially if you keep on leaving your computer idle and someone tries to mess it up by plugging in a removable device. In such situations, the restriction will defend the user against data theft. Thus, in this post, you will be guided on how you can prevent the installation of removable devices on your Windows 10 computer. There are two options that can help you in preventing the installation of any removable devices on your computer – you can either try to use the Registry Editor or use the Group Policy Editor instead. Follow whichever option you want to use the instructions given below but before you start, don’t forget to create a System Restore Point first.

Option 1 – Prevent installation of Removable Devices via Registry Editor

• Tap the Win + R keys to open 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_MACHINESOFTWAREPoliciesMicrosoftWindowsDeviceInstallRestrictions
• From there, look for a DWORD named “DenyRemovableDevices” and set its value to “0”. On the other hand, if you can’t find this DWORD, just simply create it and set its value to 0.
• Once done, exit the Registry Editor and reboot your PC to apply the changes made.

Option 2 – Prevent installation of Removable Devices via Group Policy Editor

Keep in mind that the Group Policy Editor is not available in the Home Edition of the Windows operating systems. Thus, if you are using one, just stick to the first option, otherwise, proceed to the following steps.

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” and click OK or tap Enter to open the Group Policy Editor.
• After that, go to this policy setting: Computer ConfigurationAdministrative TemplatesSystemDevice InstallationDevice Installation Restrictions
• Next, look for the “Prevent installation of removable devices” entry and once you find it, set it as “Enabled”. From this window, you should see the following description of this policy setting:

“This policy setting allows you to prevent Windows from installing removable devices. A device is considered removable when the driver for the device to which it is connected indicates that the device is removable. For example, a Universal Serial Bus (USB) device is reported to be removable by the drivers for the USB hub to which the device is connected. This policy setting takes precedence over any other policy setting that allows Windows to install a device. If you enable this policy setting, Windows is prevented from installing removable devices and existing removable devices cannot have their drivers updated. If you enable this policy setting on a remote desktop server, the policy setting affects redirection of removable devices from a remote desktop client to the remote desktop server. If you disable or do not configure this policy setting, Windows can install and update device drivers for removable devices as allowed or prevented by other policy settings.”

• Then click the Apply and OK buttons to save the changes made.
• Now restart your computer to save the changes made. This should prevent the installation of any removable devices in your Windows 10 computer.

One of the most useful utilities on a Windows 10 computer is the Windows File Explorer. It is undeniably one of the File Managers out there full of features on all the platforms. However, it is not without its issues and one of the most common ones most users encounter is when you are trying to open a folder or a location on File Explorer and it displays a message saying, “Working on it…” as it tries to load the content of that location or folder. This kind of issue mainly occurs to computers that run on an HDD although that doesn’t mean that it can’t happen to other computers that run an SDD. And so if the File Explorer on your Windows 10 computer keeps getting stuck on the “Working on it…” message along with a green animation bar moving very slowly while loading the contents of the folder, then it’s best if you follow the options given below to resolve this problem.

Option 1 – Try deleting the contents of the Automatic Destinations folder

• Tap the Win + R keys on your keyboard to open the Run utility.
• And then type “%AppData%MicrosoftWindowsRecentAutomaticDestinations” and hit Enter to open this location.
• From there, select all the files and tap the Shift + Delete key combination.
• After that, you will get a prompt that will ask you if you want to delete all the files permanently, just click on Yes. This will delete all the Quick Access cache.
• Now check if you can now open a folder or a location without the “Working on it…” message.

Option 2 – Try to rebuild the Search Index

• First, open the Indexing Options using the Search bar.
• Next, click on the appropriate listing, e.g. Users folder.
• After that, click on the Advanced button. This will open a mini-sized window and from there, go to the Index Settings tab.
• Then click on the “Rebuild” option under the Troubleshooting section.
• Now click on OK after the rebuilding is completed. This should rebuild the search index for all the files and thus, fix the File Explorer stuck on the “Working on it…” message.

Option 3 – Try to optimize the folder for General Items

You might also want to try optimizing the folder for General Items as it can help the File Explorer to load the contents faster.

• Just right click on the folder that takes time to load the contents in it and is showing the “Working on it…” message.
• After that, click on Properties to open the Properties mini window.
• From there, go to the Customize tab and click on the drop-down menu to “Optimize this folder for” under the “What kind of folder do you want?” section and then select General Items.
• Then check the checkbox with a label that says, “Also apply this template to all subfolders” and click on the OK button to save the changes.
• Restart File Explorer and check if the problem is now fixed or not.

Option 4 – Try performing a System Restore

Running System Restore can also help you resolve whatever issue that’s causing the “Working on it…” message. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Error Code 0xc004f210 – What is it?

Error code 0xc004f210 is one of the many activation errors that affect Windows 10 users. Users will be able to identify error code 0xc004f210 because of the following common symptoms which occur:

• Inability to activate Windows 10 operating system
• Message box with error code 0xc004f210

Solution

Error Causes

Error code 0xc004f210 usually occurs due to issues related to one’s product key or digital entitlement. Both the product key and digital entitlement are used by Microsoft to enable customers to activate the version of Microsoft that they have legitimate access to. If you enter the wrong product key or if you upgrade to Windows 10 but the current version of Windows to which you are attempting an activation does not match the edition of your digital entitlement, error code 0xc004f210 may occur. To correct this issue, you will need to implement one or more manual repair procedures. This will depend on the problem that caused the error to occur in the first place.

Further Information and Manual Repair

The methods below are simple procedures that Windows users lacking technical knowledge will be able to successfully complete. However, do contact a Windows repair technician if you have difficulty completing the manual repair methods listed below, or if the problem persists after completing these steps.

Method One: Enter Valid Product Key

In order to successfully activate your Windows 10 operating system and resolve error code 0xc004f210, you will need to enter a valid product key. Ensure you enter the 25-character code in the order it is given as making a simple mistake while typing the product key can lead to the reoccurrence of the error code. Follow the instructions below to enter the product key.

• Step one: Click the Start button then select Settings
• Step two: Select Update & security then Activation
• Step three: Click the Change product key
• Step four: Type in your valid product key with its 25 characters in the correct order

You should be able to successfully activate Windows 10 once you complete the process. However, move to the next manual method suggested below if the problem persists as error code 0xc004f210 could be due to an issue with your digital entitlement.

Method Two: Reinstall Windows 10 Edition that Matches Your Digital Entitlement

Digital entitlement, a new form of activation that doesn’t require the use of a product key, could be the real reason you are experiencing error code 0xc004f210 on your device. To combat any issues related to your digital entitlement, ensure the version of Windows 10 installed on your system matches your digital entitlement. This will require that you reinstall your operating system as well. After reinstalling Windows 10, follow the steps below to complete the process.

• Step one: Click the Start button then select Settings
• Step two: After selecting Settings, click Update & Security
• Step three: Select Windows Update then the Check for updates tab
• Step four: Activate Windows 10 update

If this method is successful, you will no longer see the error code 0xc004f210 pop up on your screen. However, contact a Windows repair technician to evaluate your system if the issue persists.

Method Three: Use an Automated Tool

This method involves the use of a powerful automated tool. But why is this important you might ask? A third-party tool is often the best solution when all manual repair efforts fail. Automated tools come equipped to tackle the most serious PC problems including error codes which can cause frustration and result in reduces PC performance.

If you are running a System File Checker scan but got an error message instead that says, “There is a system repair pending which requires reboot to complete, Restart Windows and run SFC again”, worry not for this post will walk you through how you can fix the problem. This kind of error can be addressed and fixed with several potential fixes which will be provided in this post. You can try to restart your computer and run a System File Checker scan again or delete the pending .xml file or use the “revertpendingactions” parameter for the DISM tool. For more information, refer to each one of the options given below.

Option 1 – Try restarting your computer and run the SFC again

The first thing you can do to fix the problem is to restart your computer and let the pending process be completed. After your computer restarted, try to run System File Checker again and see if the error is now fixed or not. If not, refer to the other options below.

Option 2 – Try deleting the pending .xml file

The next thing you can do to fix the problem is to delete the pending .xml file. How? All you have to do is navigate to this location at CWindowsWinSxS and from there, look for a pending .xml file and rename it or delete it. This will get rid of any pending tasks and will build a fresh new check.

Option 3 – Try to use the “revertpendingactions” parameter for the DISM tool

If the two options given above didn’t work, you can try using the revertpendingactions parameter for the DISM tool. If you’re not able to boot into Windows, then run Command Prompt from the Recovery Console and execute the given command below.

dism.exe /image:C: /cleanup-image /revertpendingactions

After you execute the command, restart your computer and try to run System File Checker again and see if it has fixed the problem or not.

If you have encountered the “YOU ARE NOT AUTHORIZED TO ACCESS THIS WEB PAGE AS PER THE DOT COMPLIANCE” error while trying to visit a website using either Firefox or Chrome browser, then read on as this post will guide you on how you can fix this error. Apart from this error message, you might also see an alternative message that says, “Web Page Blocked! The page you have requested has been blocked because the URL is banned as per the Government Rules”. When you get any of the aforementioned error messages when visiting a website, this means that it has been marked. It is mostly recommended to not access the site as it might be blocked for some illegal reason. However, if you are certain that the website is legitimate and safe and you believe that it has been blocked by accident, then you can check out the given methods in this post to unblock and access the blocked or restricted website. There isn’t actually a straightforward way to remove the restriction on the website or the DOT compliance. And it won’t matter what browser you use as you will still get the same error. Thus, the best way to go about this issue is for you to bypass the ISP restriction. But before you proceed, keep in mind that the ISPs (Internet Service Providers) can block any website when a request goes through their servers.

Option 1 – Try changing the DNS

If the request to access the website does not go through the ISP’s DNS server, you might have a chance in accessing it by changing your DNS settings. You can try using the Google Public DNS.

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 2 – Try to install a Proxy Extension

You could also try installing a Proxy extension or Proxy software as it could also help you access the website you are trying to open as it allows you to access the blocked websites by routing the request through their server. Aside from that, it can also hide it from ISPs to make them look like the content is coming from the proxy servers.

Option 3 – Try using a VPN connection

There are instances when the network that your computer is logged on might have blocked your access to the website you are trying to open and so to fix it, you can try to use a VPN connection. There is a lot of free VPN software out there but just make sure that you install a trusted one. Once you’ve connected using VPN, try to open the website again and see if you can now access it.

Option 4 – Check the Windows Host file

You can also try to cross check the Windows Hosts file to find out if the website you are trying to open has been blocked because if it is, then it’s no wonder why you’re getting the ERR CONNECTION TIMED OUT error in Chrome. There are instances when some third party application modifies the file and add some websites to the block lists. So if the website is indeed blocked, you need to remove it from the list.

Option 5 – Try to contact your ISP

If none of the options given above worked, then you can try to contact your ISP as there are times when DOT clears a website, the ISPs are still blocking it. Thus, it’s probably better if you reach out to them and ask them to unblock the website from their end.

When you try to open Outlook 20016 and other programs on your Windows 10 PC and end up getting an error instead saying, “Failed to register a VB Script DLL. Reinstall or run Regsvr32.exe Vbscript.dll to self-register”, read on as this post will help you resolve the problem and help you re-register the vbscript.dll file. Follow each one of the steps below carefully to fix the problem.

• Step 1: In the Start search, type “cmd” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
• Step 2: After opening Command Prompt as admin, type the regsvr32.exe vbscript.dll command and hit Enter to execute it.
• Step 3: After entering the command, it will re-register the concerned DLL file using the regsvr32.exe, a Windows OS tool. The Regsvr32 tool is a command-line utility that allows users to register or unregister OLE controls like the DLL and ActiveX (OCX) controls in the Windows operating system. After the command you entered has successfully run, you will see a message saying, “DllRegisterServer in vbscript.dll succeeded.”

On the other hand, if re-registering the DLL file didn’t work, you might have to log on to your computer using an administrator account and then try re-registering the DLL file once more. But before you do that, you need to create a system restore point first so that if anything goes wrong, you can always undo the changes you’ve made. After creating a system restore point, double-click on the downloaded .reg file to add its contents to the Registry. After that, try opening the program you were trying to open but weren’t able to because of the error. If it doesn’t work, you can always reinstall the affected programs that throw up the error and see if it resolves the problem. You could also seek the help of a one-click solution to fix the problem for you. This program is a useful tool that does not only repair corrupted registries and optimize your PC’s overall performance but also resolves any DLL issues like the Failed to register a VB Script DLL. Reinstall or run Regsvr32.exe Vbscript.dll to self-register” error. Aside from that, it also cleans out your computer for any junk or corrupted files that help you eliminate any unwanted files from your system. This is basically a solution that’s within your grasp with just a click. It’s easy to use as it is user-friendly.
