Fix Msvcr120.dll_clr0400.dll Missing Error

In recent times, some Windows 10 users have seen an error code BCM20702A0, when using Bluetooth and they are concerned as to what it is all about. We can say for certain that it has something to do with your Bluetooth driver. The error message in question is:

The drivers for this device are not installed. There are no compatible drivers for this device.

The problem here tends to no longer allow specific Bluetooth components to properly communicate with your Windows 10 operating system. It also affects laptops that do not have native Bluetooth support; therefore, the manufacturer installed a dongle on the inside to deliver the service. This is not the best way to do things because native support is always better. On the other hand, maybe you’re using a Broadcom USB Bluetooth dongle that is acting up, and as such, the error is showing. Below are solutions provided for this particular error and how to eliminate it.

1. Run the Bluetooth Troubleshooter

   Press ⊞ WINDOWS to open the menu and select settings In settings choose Update & Security Go to troubleshoot and on the right panel click on additional troubleshooters Click on Bluetooth Select Run the troubleshooter, then sit back and allow the tool to do its thing. Once you’ve completed the task, click on Apply this fix if any repairs are needed Reboot your computer

2. Install Broadcom driver from official website

   Windows drivers for Broadcom Bluetooth devices are no longer posted on their website. They should be available through Microsoft’s Windows Update service. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update. However, the Broadcom Bluetooth drivers seem to be available here on the Lenovo website. To fix the BCM20702A0 driver error, you may download and install them. After downloading it, right-click on the downloaded item, and select Run as administrator. After installation, restart your computer, then check again if it works.

3. Remove all Bluetooth drivers and USB controllers

   If previous solutions did not work, go to device manager and remove all Bluetooth devices along with all USB controllers. Reboot your computer and Windows will automatically reinstall and set all devices.

Upgrading your computer from Windows 7 or Windows 8 to Windows 10 or even upgrading Windows 10 to a new version is not that simple. The setup initially checks for all the drivers and other software utilities installed on your computer and verifies and blockages or upgrade or upgrade blocks with respect to any of those drivers or any of those software utilities regardless if you use the Windows 10 ISO or the Windows 10 Upgrade Assistant. One of these common errors, when you upgrade or update your computer, is the “The Display is not compatible with Windows 10” error. This kind of Windows Upgrade error is related to the compatibility of the Graphics Driver installed in your computer. But worry not for this post will guide you in fixing this problem. The “The display is not compatible with Windows 10” error has the same workarounds as the following errors:

• These devices aren’t fully compatible with Windows 10.
• The display is not compatible with Windows 10. Check with the manufacturer for support.
• The display manufacturer hasn’t made your display compatible with Windows 10. Check with the manufacturer for support.

To resolve this Windows Upgrade error, here are some suggestions that could help:

Option 1 – Check for incompatible drivers in your computer

• Open the Device Manager from the WinX Menu.
• Then expand the list for Display Adapters.
• Next, right-click on the NVIDIA Graphics Card list and select Enable.
• After that, right-click on it again and click on the “Update Driver Software…” option.
• After doing so, a new window will appear and from there, click on the “Search automatically for updated driver software” option.
• Then check if Windows is now able to detect your Graphics Card as well as the latest driver for it. If not, proceed to the next step.
• Right-click on the driver again and click on the “Update Driver Software…” option.
• Now click on the Browse my computer for driver software option and then click on Let me pick from a list of device drivers on my computer.
• Afterward, select a compatible driver for your computer named NVIDIA Graphics Card and then proceed.
• Wait for the whole process to be completed and restart your computer to successfully apply the changes made.

Option 2 – Get the latest version of Graphics drivers from the manufacturer’s website

In case you don’t know the manufacturer of the Graphics Processing Unit or GPU of your computer, you need to check first. They’re usually NVIDIA, Intel, or AMD. So if your computer’s Graphics Processing Unit is manufactured by NVIDIA, you need to get the latest version from their official website.

Option 3 – Try to install the latest Graphics driver in Compatibility Mode

If you’re not able to install the Graphics drivers you’ve downloaded, you can try installing them again but this time using Compatibility mode. Follow the steps below to do so:

• You need to download the driver and place it on your desktop.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you should see two options:
  • Compatibility troubleshooter, and let Windows figure out what works best for you. If it fails, follow the next.
  • Manually choose the version of Windows it was correctly working.
• You also have the option to change the DPI settings and see if that helps. Then click the Apply and OK buttons.
• Now right-click on the file and select the “Run as administrator” option to install. After that, you should now be able to change your screen aspect ratio to what you were using early on.

Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.

Option 4 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job.

TPM 2.0 requirement for Windows 11 has produced a lot of discussions since it was announced. A lot of somewhat older hardware seems to be left behind with this decision from Microsoft. So naturally, when something like this is announced, especially when it is stated it is the must-have thing, people find a way to break it and to prove it is not the case. In that spirit, I am proud to present you with not one but three-way you can install Windows 11 on hardware that does not has TPM 2.0. Please note that by bypassing this you will not be able to use some Windows 11 features tied to modules like Device encryption, vTPM in Hyper-V, and all TPM-related services. I will cover methods from the most simple and straightforward ones to the more complicated using registry editor.

Bypass TPM with changing installation media

For this method to work you will need both Windows 10 ISO and Windows 11 ISO since it will require some file copying between them. You will also need Rufus or another tool to make a new installation media once files are copied All you have to do in this method is to go into your Windows 10 ISO and delete the install.esd, then just copy install.wim from Windows 11 installation media into the same place, and you are done. Make install ISO with Rufus and install Windows 11.

Change DLL on installation media method

For this method, you will need everything like in the previous one and the process is almost the same, but this time instead of migrating the whole installation file, we will just replace the appraiserres.dll file. Copy appraiserres.dll file from your Windows 10 installation media over the same file on Windows 11 installation and you are good to go.

Bypassing TPM via registry editor

If for some reason previous easy solutions have not worked for you do not lose hope just yet, there is one more way you can bypass TPM. In this given method you will not need Windows 10 installation media but the process is a little more complicated than previous ones.

1. Create Windows 11 media installation
2. Start the installation process
3. Click the Next button.
4. Select region, language, and time when asked. You can change these settings later.
5. Click the Install now button.
6. If your device was already activated, click the I don’t have a product key option to continue.
7. Click the Next button. Select the edition of Windows. When you’re installing the OS on an existing device, Windows won’t activate if you select the incorrect edition.
8. Click the Next button.
9. Select the I accept the license terms option and click next.
10. Select Custom: Install Windows only (Advanced)
11. During the Windows installation screen, now you will see a message stating that the PC can’t run Windows 11 if you do not have TPM 2.0
12. On this screen, press SHIFT + F10 to open Command Prompt window.
13. Launch the registry editor, type regedit.exe in Command Prompt, and press ENTER
14. Create a new key “LabConfig” by right-clicking on the Setup key and select New > Key under HKEY_LOCAL_MACHINE\SYSTEM\Setup.
15. Type LabConfig and press ENTER.
16. Right-click on the LabConfig key.
17. Select New > DWORD (32-bit) value.
18. Create two values: BypassTPMCheck and BypassSecureBootCheck.
19. Set their DWORD32 value to 1.
20. Press ENTER.
21. Close the Registry Editor.
22. Type exit in the Command Prompt and press ENTER or close its window.
23. Press the back button in the Windows installation setup if it still says “This PC can’t run Windows 11”.
24. Accept the terms & conditions.
25. Select Custom: Install Windows only (Advanced) option and configure the partition with the current installation.
26. Click the Next button.
27. Finish Windows 11 installation

Random freezing in a Windows in the middle of work can be a very frustrating experience and can even cost us the loss of work. From time delays to sometimes complete crashes this behavior is something that every PC user wants to avoid or at least have very little of. In this article, we will cover solutions on what to do and how to fix the random freezing of computers.

1. Run a virus scan on your computer.

   Viruses and other malware can cause freezes and other issues in your computer, run a complete system scan for any kind of viruses and malware and if needed remove them.

2. Uninstall applications that you are not using

   Besides taking your hard drive space some applications can have and require to have some services always running on your computer which can cause some issues, if an application is not needed and it is not used, removing it might solve freezing issues.

3. Increase RAM memory

   Sometimes the problem with freezing is not a software issue, having less RAM memory than the application requires can cause the application not to work properly and it can cause freezing of the entire system since precious RAM can not be allocated to the required application.

4. Run system checker

   Corrupted Windows system files can cause freezing of the entire system, to fix this, start the command prompt in administrator mode and type sfc /scannow

5. Keep running applications to a minimum

   Having too many applications running in the background can drain system resources and can cause system freezes because of lack of memory. Close applications that are running in the background and keep them minimal.

6. Delete files and folders which you are not using

   Having many files and/or folders on the hard drive can cause a lot of system resources to be wasted, from indexing size to less free space for caching. If you have files that you no longer need, removing them will free up space and can increase performance and introduce the stability.

7. Run memory check

   Memory issues could lead to system freezing. When an application needs to write or read to a corrupted memory cluster, freezing will occur since it can not. To check memory bring up run dialog and type in ti mdsched.exe, click on restart now and let the memory test finish.

8. Update all drivers

   Hardware issues can cause freezing of applications and having the latest drivers can make a world of difference. Make sure that you have all device drivers to the latest versions.

9. Optimize Disk drives and check for errors

   Windows 10 has built-in tools to check hard drives for errors and to optimize them, use them in order to see if this issue is causing freezes.

10. Clean your registry

    A Clean registry is a happy registry and Windows is appreciating it. Make sure that you do not have any keys which you do not need in the registry and that long-forgotten application trails are deleted for good.

11. Upgrade SSD firmware

    Like updating drivers, updating firmware is also important, and having the latest firmware for your SSD can help a lot, newer firmware can eliminate freezing if the issue was in Windows not using SSD properly.

12. Update BIOS

    Like updating SSD firmware can help so it can update Firmware on your BIOS. Make sure that you have the latest firmware version and freezing can go away if that was the issue.

The Volsnap.sys is a Windows operating system file that is related to the Volume Shadow Copy Service or VSS. It is known to cause a Blue Screen of Death error. The main cause of the Volsnap.sys Blue Screen errors include conflicts with the RAM, issues with the hard disk, incompatible firmware, corrupted drivers, malware infection, and many more. Despite its many possible causes, its fixes are quite straightforward so won’t have any problem following them. The Blue Screen errors that are related to the Volsnap.sys file are:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• SYSTEM THREAD EXCEPTION NOT HANDLED
• IRQL NOT LESS OR EQUAL

You might want to try performing System Restore as it could resolve Blue Screen errors like the ones related to the Volsnap.sys before you proceed with the troubleshooting tips given below. To run System Restore, follow these steps:

• 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.

If System Restore didn’t help in fixing the Blue Screen error, now’s the time for you to resort to the troubleshooting tips provided below but before you get started, make sure that you create a System Restore point first.

Option 1 – Check if the Volume Shadow Copy service is running and restart it

The first thing you need to do is check if the Volume Shadow Copy service. To do that, refer to the following steps:

• Click on Start and type “cmd” and right-click on Command Prompt from the search results.
• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, type “net stop sdrsvc” and hit Enter to execute the command in stopping the Volume Shadow Copy service.
• Next, type the “net start sdrsvc” command and hit Enter to start the service again.

Note: You can also restart the service using the Windows Services Manager.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager.
• From there, look for the Volume Shadow Service (sdrsv) from the list of services. Its Startup type should be set to Manual by default.
• Restart the service and if you don’t encounter any error while you turn it on, re-run the backup service and see if the backup process runs successfully.

Option 2 – Try checking the Memory for the Errors using Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the Volsnap.sys Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

• Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select your preferred option, your computer will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

Option 3 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or rollback the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then go to the section of IDE ATA/ATAPI controllers as well as Storage Controllers 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.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 4 – Try to run the CHKDSK utility

Running the CHKDSK utility might also help you resolve the Volsnap.sys Blue Screen error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 5 – Run the System File Checker Scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer.

Option 6 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like Volsnap.sys. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.

If error code 0x80070490 in Windows 8 or 8.1 persists on your device, proceed to the solution below.

2. Perform Clean Boot

A clean boot is one of the best ways to reduce conflict among files – an issue that may arise whenever users update, install or run programs on their Windows device.

To run a clean boot, your device reboots using limited drives and programs. The process allows you to identify which conflict among programs is causing errors on your Windows device.

You can access the clean boot tool by entering msconfig in the search box. Select Services, then System Configuration. Check the Hide all Microsoft services checkbox then select Disable all. Next, go to the Startup tab, click and open Task Manager. After selecting the Startup tab, make sure you right-click each startup program. Click Disable from the context menu then close Task Manager when done. Select OK on the System Configuration menu then restart your machine to clean boot Windows 8 or 8.1.

If the clean boot successfully identifies and resolves issues with corrupted files, you will be able to access updates using Windows Update or Microsoft Update. Error code 0x80070490 will no longer occur. But if that proves unsuccessful, other options are available below including running Windows Update Troubleshooter.

3. Run Windows Update Troubleshooter

This method can provide a simple solution for users as it verifies whether your Internet connection, network adapter and Windows Update services are functioning properly. However, if you are uncertain as to whether you will be able to troubleshoot, seek assistance from a qualified Microsoft technician.

To run Windows Update Troubleshooter, simply download from Microsoft’s website. Be sure you are downloading the tool recommended for your operating system, in this case Windows 8 or 8.1. After you download Windows Update Troubleshooter, run it to enable the tool to check for and resolve update issues on your device.

4. Use DSIM or System Update Readiness Tool

The System Readiness Tool or DSIM is another method you can use to correct issues related to error code 0x80070490. This tool checks problems on your system that might prevent your computer from performing Windows updates including issues related to damaged system files.

Once you download and install this tool, it will be able to run automatically. The process may be technical, however, requiring specialized knowledge to successfully download and run the tool. Consider getting assistance from an IT professional in this case. Also, check Microsoft's online resources to download the tool.

5. Use an Automated Tool

Having an automated tool at hand will enable users to always be prepared. Download a powerful automated utility tool to provide solutions whenever error codes or other problems affect your Windows 8 device.

Each you connect time external devices like scanners, printers, and the likes to a Windows 10 computer, the device either pushes the drivers through the USB or any other port, or you are expected to install the drivers through external media. In both cases, the driver will be loaded into the system, allowing you to use the device. However, it doesn’t always go smoothly as you could encounter some errors like the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory ( Code 38 )”. If you encounter such an error in the Device Manager, then this means that a previous version of the device driver is still in memory and that each time the device is used, that previous version is loaded into memory and then unloaded which triggers the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory (Code 38)” error. This kind of error occurs if the operating system loads the unwanted driver or if it fails to unload the driver. It could be that there is an obsolete version of the driver that’s still installed in the system or it could also be that you need to update your USB drivers as they could be outdated or the problem could also be due to some third party program that is interfering with the installation. Whatever the cause is, here are some suggestions you can check out to resolve the problem.

Option 1 – Uninstall previously installed drivers and reinstall their latest working version from the manufacturer’s website

The first thing you can do is to uninstall the drivers that are currently installed on your computer and then reinstall their latest working versions from their official sites. This kind of error is commonly encountered while loading drivers for scanners and printers. This is due to the fact that their drivers and software come along with a package which is usually in external media like CD or DVD. So when you install the software package, there’s a possibility that a newer version has been launched by its manufacturer. When that happens, you have to uninstall the previously installed driver package and then download the drivers from the manufacturer’s website and install them.

Option 2 – Run the Hardware and Devices Troubleshooter

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.

Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.

• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 4 – Restart your computer in a Clean Boot State

If the first three given options didn’t work and you still see the error when you connect external devices, you can try putting your computer in a Clean Boot State and then try connecting them again.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect the external devices and check if the error is now gone.

Each year Steam makes a couple of large sales, and each year there are speculations and leaks on the date when the sale is going to happen and when it is starting. It seemed that Steam has become aware that these leaks will not stop and that store really cannot hide that kind of important date from the public so in the latest news Steam Purley has just given the date of this year's big winter sale. Probably tired of even trying to hide it, Steam has released that this year's big Steam Winter sale is officially starting on December 22nd, 2021, and closing on January 5th, 2022. So if you have someone to buy a gift or just want to drop a few great games in your library at a low price this is the time when you should do it.
