Fix The backup application could not start

nslookup is a command-line tool that helps in finding the DNS records of a website. It sends a name server query to the DNS and obtains the corresponding IP address. Aside from that, it can also perform some complex functionality such as finding details about FTP server, Mail server and many more but most of them are used by administrators. The best thing about nslookup is that it queries the DNS server directly and it does not rely on the cache. On the other hand, there is another tool called PING that is used to verify connectivity. PING sends a packet of information to the IP address or Domain and gets back a response in the form of packets. So if everything goes well, all packets are received but if not, it will help you find out where the delay in the network exactly is. However, the ping command does not always attempt a DNS lookup which means that it might be using the DNS cache and use the IP address available in that table. Although both nslookup and PING help you in identifying the host or IP address, however, they don’t always work and sometimes fail. So if your nslookup works but ping fails on your Windows 10 PC when querying the IP address of a website then it could be caused by many reasons. It could be that the nslookup queries work for you but when you try to use PING, it fails. For instance, if you open the abc.com website, here’s how it will look like:

nslookup xyz.com Server: dns.company.com Address: 192.168.1.38 C:> ping xyz.com Ping request could not find host xyz.com. Please check the name and try again.

The domain is converted into an IP address and then data is sent to that IP address when you use PING. So when a reply comes back it means that the data is going back and forth to that domain without any problem. However, if the DNS fails to resolve the IP address of the website or if your PC does not attempt a DNS lookup, you will receive a similar error message that says, “Could not find host” and so on. To resolve this issue, here are some options that might help.

Option 1 – Reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the issue with nslookup and PING. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 2 – Force Windows to do a DNS lookup using FQDN

• Go to Settings > Network & Internet > Status > Change adapter options.
• From there, right-click on the network and select Properties.
• Next, in case you’re using IPv6, from the list of connections available in the list, select Internet Protocol Version 4.
• Then click on Properties and click Advanced.
• After that, switch to the DNS tab and select “Append these DNS suffixes (in order)” and click on the Add button and then add “.” as a suffix so that each time you query using PING and another tool, it will add a “.” at the end and will force the lookup.

Option 3 – Make sure that there is only one default gateway

If your computer has more than one NIC connected and there are multiple default gateways, then it will most likely create confusion which is why you need to remove the default gateway from the configuration of all NICs and make sure that there is only one default gateway.

Option 4 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the nslookup and PING issues. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – 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 PING fails even when nslookup works. There are instances when some third-party application modifies the file and adds some websites to the blocklists. So if the website is indeed blocked, you need to remove it from the list.

Option 6 – Delete the WLAN Profiles

Deleting the WLAN Profiles might be a good idea if you are not able to connect to the internet on your computer and if you’re using Wi-Fi. It could be that the networks that were connected previously have gone rogue which is why it is not connecting properly. And so deleting the WLAN profiles might help you in fixing the issue with nslookup and PING.

Option 7 – Reinstall the Network Adapter Drivers

• Tap the Win + R keys to launch the Run window and then type in the “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 it.
• Then right-click on each one of the Network drivers and select “Uninstall device”.
• Restart your PC.

In case you don’t know, Windows 10 actually allows users to set the Keyboard Repeat Rate and Repeat Delay. Both of these terms are interrelated and when you make active, any text field or an editor and then press and hold a single character key, it will quickly type the character for the first time and will show delay until the second and later characters appear. This is what you call the Keyboard Repeat Delay. On the other hand, the rate at which the later character appears is known as Keyboard Repeat Rate. There are two ways you can set the Keyboard Repeat Rate and the Keyboard Repeat Delay on Windows 10. The first one is using the Keyboard Properties while the second one is using the Registry Editor.

Option 1 – Set up Keyboard Repeat Rate and Repeat Delay via Keyboard Properties

• First, tap the Win + R keys to open the Run dialog box and type in “control keyboard” in the field, and hit Enter to open the Keyboard Properties.
• From there, you can use the slider to make the respective options for both Keyboard Repeat Delay and Repeat Rate shorter or whatever you prefer them to be.
• You should also see a text field in the mini window where you can test out your preferences. Once done, click on the Apply and OK buttons to save the changes made.

Option 2 – Keyboard Repeat Rate and Repeat Delay via Registry Editor

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_CURRENT_USERControl PanelAccessibilityKeyboard Response
• From there, you can set your own value for both the AutoRepeatDelay and AutoRepeatRate registry keys so that you can set the Keyboard Repeat Rate and Repeat Delay in Windows 10.
• Once you’re done, exit the Registry Editor and restart your computer to save the changes made.

A number of users reported lately that their Windows 10 PCs automatically boots into the BIOS whenever they start their computers. And when they tried to exit the BIOS and restart their computers, it still boots into the BIOS. If you are one of the users who experience the same problem, worry not for this post will walk you through what you can do to resolve the problem. Each time a Windows 10 computer boots, it goes through a lot of processes and one of them is where it checks the computer for any hardware issue such as hard drives, peripherals, as well as external devices. So if it finds some issue, the computer will halt the boot process and will boot into the BIOS. To fix this, there are several suggestions you can try. You have to check if you’ve pressed any key, especially the F2 or F12, or Del keys. You also have to check the peripherals and external devices in your computer or update the BIOS or reset it. For more information, make sure to follow each one of the options laid out below.

Option 1 – Try to check for any pressed key

The first thing you can do is to check for any pressed key. This might not make any sense but a pressed key can actually cause this problem. So you have to check if you have the F2 or F12 or Del buttons pressed since these are hardware keys that are usually set by the OEM to boot into the BIOS.

Option 2 – Try checking the physical device connections

You might also want to try checking if there are other devices that are connected to your PC. This is because the configuration of the BIOS or UEFI might be configured in a way that any external device connected to the computer has a higher boot priority compared to the hard disk.  And if it’s really the case, the externally attached disk might be the drive your computer is trying to boot into and not the hard disk. In such cases, Pen Drives, USB storage devices, CDs, DVDs, and so on, are included in this category of physical device connections.

Option 3 – Try to set a proper boot device

If the Boot Manager wasn’t able to locate a proper boot device, then it could be the reason why your computer boots into the BIOS when you turn it on. Thus, you have to check if there is an available proper boot device. You can usually find it under the Boot priority section. However, if you’re unable to locate your hard drive or SSD under the Boot device, then you have to change the hard drive but you have to check first if it is properly plugged in and that it works on other computers. If it works on other PCs, then the problem lies in the motherboard of your computer, and in that case, you have to consult its manufacturer.

Option 4 – Try to update the BIOS

Updating the BIOS can help you fix the issue but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Note: If updating the BIOS didn’t help, you might want to consider resetting it instead.

Option 5 – Try resetting the BIOS/UEFI configuration

You might also want to reset the BIOS configuration which will lead to arranging the boot configuration since it is intended by the manufacturer. Note that this will get rid of any blockage in the boot process. All you have to do is take out the CMOS battery for a couple of seconds and then put it back again. After that restart, your computer and will be booted directly into Windows. Resetting the BIOS would also get rid of any password set for BIOS and you need to change your CMOS battery in case it didn’t work.

When you get an igfxem.exe error in Windows, it is not really clear what does this means, usually, Windows throw us some code or we get a DLL error, rarely we get an EXE error. So what does this error means? Intel Graphics Executable Main Module, shortly called as IgfxEM module is a part of the Windows operating system. When you run Microsoft .NET Framework applications that use the AS/400 Data Queue ActiveX control (Mseigdq.dll) to read from and to write to IBM iSeries (AS/400) data queues, you may experience this error. In order to overcome this error and cope with it try the following things:

1. Increase Virtual Memory

   Go to the Start Menu and click on Settings. Type performance. Choose Adjust the appearance and performance of Windows. In the new window, go to the Advanced tab and under the Virtual memory section, click on Change. At the bottom of the new window, check what the Recommended value is and how it compares to Currently allocated. If the current setting is significantly less than the recommended, uncheck the Automatically manage paging file size for all drives box at the top of the same windows and then click on Custom size. Enter the Recommended value in the Initial Size box, and a larger figure in the Maximum size box. Click OK to save the new settings.

2. Download and update .NET framework

   Go to the Microsoft website and download the latest .NET framework. Once the download is complete, install the package following onscreen instructions.

3. Reinstall INTEL graphic drivers

   Go to the intel website and download the latest graphic drivers for your graphic card model. Once the download is complete, install the package following onscreen instructions.

4. Run SCF scan

   If all else fails, run command prompt and inside type sfc /scannow

Windows uses 2 types of keys for its activation, KMS or MAK. These keys should work without any issues since they are elevated with higher permissions but in some cases, they are by accident run without their proper permission, and then we have access denied error or error 0x80070005 To resolve this issue please first check if not by any chance your antivirus or firewall is preventing slmgr.bs file to access the right permissions, that being said if the previous solution is not working note that you have to be an administrator of the system or have administrator privileges. As an administrator, you will have to use Software Licencing Management Tool or short SLMGR.VBS, a VBS file in Windows used for its activation purposes. As an administrator, open Command prompt with admin permissions and then run slmgr.vbs This will make sure that activation goes through, make sure to use proper options like:

/ipk <ProductKey> or /ato [<Activation ID>]

Steam has cemented itself as the largest digital game shop in the World. First, release all the way back on September 12^th, 2003, it was meant to be a standalone software client aimed to deliver updates to Valve’s games. It was soon expanded to include titles from third parties. The greatest Steam expansion and its popularity started in 2004 with the release of Half-life 2. Steam allowed prepurchased editions to be downloaded before the official release of the game making it available for play the moment it was officially out. Very soon after Steam gained its popularity, Valve has opened doors to other developers and offered them to use Steam as means for a digital distribution platform. Today it hosts over 30000 different game titles, not including DLC or applications. And how soon Valve’s steam deck is coming out soon we would like to share some great tips and tricks about Steam itself for easy everyday gaming.

Steam guard account security

Security of any of your accounts should be something that you really take seriously. So as always use a strong password for Steam but if you want an extra layer of security for it, and you should, use the Steam built-in feature: Guard Account Security. In order to activate Security Guard go to Steam>Settings>Account>Manage Steam Guard Account Security. Once enabled you will be able to use the Steam mobile application for special code when opening Steam or your email address.

Use Steam beta feature

Once a Steam account is created by default you will download and install the client. In the client, you will have the latest features available but there are more Steam features than default ones, beta features that can offer some improved and new functionality, and do not worry, they are stable and bug-free. I have been in Steam beta for years and not even once have I had any issues with the client itself but I have always had the latest features that will come to regular users later. To enable beta participation to go to Steam>Settings>Account, open the drop-down Beta participation menu, and choose Steam Beta Update. Confirm on OK and restart the Steam client. You will now get all the latest features first.

Manage your library via Collections

The collection is a neat idea for organizing your large game library into different collections or sections easily expanded and contracted for easier navigation and organization. To add the game to a collection just right-click on it and select Add To>New Collection, make a name for a collection like action, RPG, or whatever rocks your boat, and you are done. Once the collection is created other games can be added to it simply just by dragging it into the desired collection.

Make shelves

Shelves are ways to see your collections in the larger areas of the Steam clients. By clicking Add Shelf>Choose a Shelf, you can now add your collection to a shelf on the larger part of the client as a horizontal scrolling container with your chosen games. There are also some predefined shelves like All Games, Recent friend activity, and more.

Hide Game from Library

By right-clicking on a game and selecting Manage>Hide This Game you will remove the game from the active view of your Steam library. Note that the game will still be owned and a part of your library, you will just not be able to see it. This is a great feature when for example you have some things that came as a part of the game pack you are not really interested in when you have 2 different versions of the same game as for example standard and deluxe edition or just by simply not wanting to have game visible in the library. You can find a hidden game by typing its name in the search box and from there you can unhide it.

Play game soundtracks inside Steam

Some games offer you to purchase their soundtracks if you like music from them and some even include OST with a regular purchase. Steam lets you play these soundtracks and even lets you import your own music library folder into it in order to play all of your music inside the client itself. It has even options to automatically stop music playing once the game is run and you can make playlists as well. Your purchased game soundtracks are automatically included, the rest you will need to add by pointing Steam to the folder where you keep music in.

Configure gamepad

Inside Steam, you can configure your gamepad’s general settings, big picture settings, desktop settings, etc. Steam embraced the idea that many OC users these days own and play with gamepads so it has implemented configuration options inside it. To configure your pad go to Steam>Settings>Controller.

Use big picture Steam mode

Big picture mode is Steam's idea of making Steam an entertainment center. Once it is activated it switches from the application into full-screen mode aimed at large TV screens or monitors. You can easily navigate through it via gamepad, mouse, keyboard, or other devices. You have access to the store, your game library, etc. Same as your typical steam app but a little different. You can easily activate it via View> Big Picture Mode and see for yourself is this something you prefer over a standard application layout.

Enable Steam Cloud

Steam Cloud is a great feature that uses cloud storage to save your game progress meaning that you can easily switch to another PC, install games there and continue where you have left off. Many games support this feature instead of keeping saves locally and it is a great feature worth turning it ON. To turn and use Steam Cloud service go to Steam>Settings>Cloud>Enable Steam Cloud Synchronization. Just remember to check does game you are playing supports this option.

Share your Games via Family sharing

Family sharing is a Steam feature allowing you to share your game library with up to 5 accounts on up to 10 different devices. This is a great way to let other members of your family or even close friends enjoy some games you have or vice versa. They will get as well their own save games so you can sleep safe knowing that your progress can not be changed or hindered. Family sharing can be turned ON by logging into PC Steam client where you would like to share your library and navigate to Steam>Settings>Family and then clicking on Authorize Library Sharing On This Computer.

Refund a game

Sometimes the game is not the same as advertised, sometimes it will not work on your PC, sometimes hardware specifications are too high making the game unplayable, etc. For whatever reason, you might have Steam offers you a full game price refund if you wish to do so, you only need to meet 2 criteria, the game must have been purchased within 2 weeks period, older purchases cannot be refunded, and your game playtime must not be over 2 hours of game time. If you fit into this category all you need to do in order to get the full money back is going to Help>Steam Support, pick a recent game from the eligible list, and ask for a refund.

Gift a game

As you can buy gifts for your friends or loved ones in real life, Valve made sure you can do it in digital as well. Gifting game via Steam is simple and straightforward. Choose a game you wish to gift, go to your shopping cart and instead of clicking Purchase for myself, click on Purchase As a Gift, from there you will be taken to your friend list to choose to whom you would like to gift a game along with the option to write a little note to the receiver like happy birthday, enjoy or whatever.

Stream games in Steam itself

Although Steam is not there yet in streaming as Twitch or Facebook gaming is, there is an option to stream your game sessions on it. Click on Steam>Settings>Broadcast to make all adjustments and start streaming. You can also watch streams from your friend list and Steam is now broadcasting popular streams directly to its client if you want to watch it.

Take a game screenshot

By pressing F12, you can take a screenshot from any game and save it inside your Steam cloud library. You can change of course this default screenshot key via Settings>In-Game and if you would like to see your screenshots you can always do it under View Screenshot Library on a game’s page. That’s it, our Steam tips and tricks for easy and good gaming life, I hope to see you soon on errortools.com for your daily articles, tips, and tricks.

A lot of users have experienced various issues either in installing a Feature or a Windows Update. One of these errors is the one with the error code 0x80d02002. If you are one of the users who is facing this problem right now, then the working solutions given in this post will surely help. The Windows Update error code 0x80d02002 indicates that Windows 10 fails to upgrade or install as there is some issue with the files that have been downloaded and Windows encounters an error in installing them. Thus, the best thing you can do in such a case is to start the installation from scratch but before you do that, here are some suggestions that might help.

Option 1 – Try to rename the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits rename c:windowsSoftwareDistribution SoftwareDistribution.bak

• After entering these commands, it will stop the Windows Update Service, the Background Intelligent Transfer Service, and rename the SoftwareDistribution folder.
• Next, got to the C:\Windows\SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Option 2 – Try to reset the Catroot2 folder

You can also try resetting the catroort2 folder as it is known to fix tons of Windows Update issues including the Windows Update error code 0x80d02002. Both the Catroot and catroot2 are Windows operating system folders that are required for the Windows update process.  So when you run the Windows Update, the catroort2 folders stores the signatures of the Windows Update package and helps it in the installation. It makes use of the “%windir%System32catroot2edb.log” file in the updating process. Afterward, the updates are stored in the SoftwareDistribution folder which is used then by the Automatic Updates in order to execute the updating process. Keep in mind that you must not rename or delete the Catroot folder. Although the Catroot2 folder is recreated automatically by Windows, the Catroot folder isn’t.

Option 3 – Try running the DISM tool to fix the broken Windows Update client

The Windows update/upgrade error 0x80d02002 might be caused by some issues in the Windows Update client so you need to run the DISM tool to repair it. Note that you have to use another computer or another Windows from a shared network to fix it.

Option 4 – Try to run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80d02002. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.

Option 5 – Try to run Microsoft’s troubleshooter online

You also have the option to run Microsoft’s online troubleshooter which could help you fix Windows Update errors.

California's Department of Fair Employment & Housing has widened its anti-discrimination lawsuit against Activision Blizzard and claims the publisher has been shredding vital documents relevant to the ongoing investigation. A recent report from Kotaku described the department as offering poorly paid, highly insecure positions, with a culture of hostility towards LGBTQ+ testers. The DFEH's rewording of "employees" to "workers" now hopes to take these contractors' experiences into account. "As a contract employee, I feel there's a lot of pressure to excel, impress, and move through the ranks as fast as you can before your contract ends and you're forced to go 3 months without income or find another job," Axios reports one worker saying. "I take pride in what I do, but it feels like it's never enough." Activision's contentious hiring of union-busting third-party law firm WilmerHale "directly interferes" with its own investigation, it says. By going to WilmerHale, Activision appears to be claiming that all work related to the investigation is privileged and can't be shared with DFEH. The suit also claims that Activision HR shredded documents related to "investigations and complaints", against its legal obligation to retain them during the investigation. The relevant parts of the updated lawsuit were shared by Axios reporters Stephen Totilo and Megan Farokhmanesh, the former also noting that the DFEH "fixed their misspelling of Bill Cosby's name". "DFEH is also informed and aware that documents and records have not been maintained as required by law or by the DFEH's Document Retention Notice," the complaint reads, "including but not limited to documents related to investigations and complaints were shredded by human resource personnel and emails are deleted thirty days after an employees separation."

Speculation and answer from Activision Blizzard

Blizzard employee Jessica Gonzalez suspects that the costs of fines associated with destroying these documents may have been an easier blow for Blizzard to take than any penalties drawn from their existence in helping the lawsuit go through. In an email to Kotaku, Activision denied the shredding allegations and issued a statement outlining steps it had taken to improve company culture—including the ousting of high-level executives like Blizzard president J. Allen Brack. The full statement reads: "Throughout our engagement with the DFEH, we have complied with every proper request in support of its review even as we had been implementing reforms to ensure our workplaces are welcoming and safe for every employee. Those changes continue today, and include:

•     Several high-level personnel changes
•     Revamped hiring and recruiting practices requiring diverse interview panels
•     Greater transparency on pay equity
•     Expanded and improved training and investigative capabilities for human resource and compliance staff
•     Created investigation teams outside of business units to support greater independence
•     Restructured divisions to support greater accountability
•     Enhanced review processes to include evaluation of managers by employees
•     Clear boundaries on workplace behavior with a zero-tolerance approach to harassment and other actions that diminish or marginalize.

"We strive to be a company that recognizes and celebrates the diverse talents and perspectives that lead to the creation of great, globally appealing entertainment. We have provided the DFEH with clear evidence that we do not have gender pay or promotion disparities. Our senior leadership is increasingly diverse, with a growing number of women in key leadership roles across the company. "We share DFEH’s goal of a safe, inclusive workplace that rewards employees equitably and is committed to setting an example that others can follow."

California and RIOT

Beyond Activision Blizzard, California's DFEH has also probed into League of Legends creator Riot Games, accusing the studio of dragging its heels over sexual harassment allegations dating back to 2019. Riot denied the allegations, telling us that it "will never retaliate against anyone for talking to any government agency".

If you encounter the MUP_FILE_SYSTEM Blue Screen error with a value of 0c00000103, then it indicates that the multiple UNC provider or MUP has got an invalid of unexpected data. This can lead to the fact that the MUP cannot channel a remote file system request to a network redirector, the UNC, or Universal Naming Convention provider. There are several ways you can fix the MUP_FILE_SYSTEM Blue Screen Error on your Windows 10 computer, you can try to check the hardware of your computer physically, update or rollback some device drivers, run the Driver Verifier Manager, remove any hardware you’ve installed recently or fix issues related to IRQ. Use the given options below as reference to fix the MUP_FILE_SYSTEM Blue Screen Error.

Option 1 – Try to physically check the hardware

The first thing you can do is to check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Network Card of the computer. You might want to use a small blower or you could also use a soft cloth and run the components gently. Make sure that you don’t damage any parts with moisture or cause harm to any circuits while you carry out this task.

Option 2 – Try to rollback, update several device drivers

You can try to roll back, update or disable certain device drivers on your computer to resolve the MUP_FILE_SYSTEM Blue Screen error.

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the device drivers related to the Network Card, Chipset, Disk Drive, and the Graphics Drivers and any other driver related to MUP.sys and SwapBuffers.sys system files
• After that, right-click on each entry of the device drivers and select the “Update Device” option from the menu.
• Now follow the next on-screen instructions that appear and then restart your computer.
• After restarting your computer, check if the Stop error is now fixed.

Option 3 – Configure the Driver Verifier Manager

The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues. And so if you want to fix the MUP_FILE_SYSTEM Blue Screen error you need to use the Driver Verifier Manager:

• Type in the keyword “Verifier” in the Cortana search box to search for Verifier in Windows 10.
• After that, select the option “Create custom settings”.
• Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
• Next, select the option “Select driver names from a list” option.
• Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
• Then click on the Finish button.
• Open Command Prompt as administrator and execute this command – verifier /querysettings
• The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
• Open the Command Prompt as admin again and run this command – verifier /reset
• The command will reset the Driver Verifier. Once the process is done, restart your PC and check.

Option 4 – Try to disconnect or disable newly installed hardware

In this option, you will have to disable or remove the hardware you’ve just installed recently since external devices could be the one that’s causing the Blue Screen of Death error to appear. To do that, just disconnect any external device that’s connected to your computer physically and then check if it fixes the MUP_FILE_SYSTEM Blue Screen error.

Option 5 – Try fixing IRQ-related issues

The Stop error might have something to do with an issue related to IRQ. You can verify it by switching your PCI Cards around. Aside from that, you can also check if the IRQ2 is assigned to a COM Port that is unavailable at that time.

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 MUP_FILE_SYSTEM. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 7 – Perform a System Restore

Performing System Restore might help you in fixing the Blue Screen error. 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.
