Fix 0x800704C8 Error in Windows 10

One of the most useful and powerful built-in utility in Windows 10 is the DISM tool. This tool can be used with the Command Prompt command line as well as for other purposes. However, it is not without flaws and there are times when you may encounter some issues while using it. One of the problems you can get while using the DISM tool is the following error:

“The scratch directory size might be insufficient to perform this operation”

This kind of error in DISM occurs when the DISM command is executed from the Windows Recovery Environment due to the limited size permissions of a delivery where the operating is being performed. To fix this DISM error, you need to follow the instructions laid out below. Step 1: First, tap the Win + R keys to open the Run utility and then type “cmd” in the field and tap Enter to open Command Prompt. Step 2: Next, you have to specify a scratch directory that contains the Windows folder and to do that, you can either use the DIR command or the BCEDIT command. So in the elevated command prompt type and enter “dir” or “bcedit”. Step 3: After that, you will see a list of folders inside the C: partition. Now you have to create a folder named “scratch” inside the partition. To do so, execute the following command:

mkdir C:Scratch

Note: The command you just entered will create a directory inside the root of the C: partition named Scratch. Step 4: Now that you’ve created the Scratch folder, note that each time you run any of the DISM commands, you have to enter the following code snippet in them:

/ScratchDir:C:Scratch

 Note: For instance, if you are using the DISM tool to repair the offline Windows image, instead of executing the “Dism /Online /Cleanup-Image /RestoreHealth” command, you now have to execute the “DISM /Image:C: /ScratchDir:C: Scratch /Cleanup-Image /Restorehealth” command. And if you want to remove a selected installed update package, you can use the “DISM /image:C: /ScratchDir:C:Scratch /Remove-Package /PackageName:Package_for_RollupFix~31bf3856ad364e75~amd64~~16299.196.4.9” command. Keep in mind that the mentioned package is only an example. And lastly, you also have to replace the drive letter in the new code snippet when you execute the commands given above.

Usually when online service is not working or when something goes wrong online it is DNS, well that is what most of the time is the case. And yes, DNS or Domain Name Server seems to be an issue with Facebook being completely down along with Instagram and wassap. The true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP. Cloudflare VP Dane Knecht was the first to report the underlying BGP problem. This meant, as Kevin Beaumont, former Microsoft's Head of Security Operations Centre, tweeted, "By not having BGP announcements for your DNS name servers, DNS falls apart = nobody can find you on the internet. Same with WhatsApp btw. Facebook has basically de-platformed themselves from their own platform." Many people are very annoyed by this and with the fact that they cannot use their social media platforms but it seems that Facebook employees are in even bigger annoyance as it was reported that Facebook employees can't enter their buildings because their "smart" badges and doors were also disabled by this network failure. If true, Facebook's people literally can't enter the building to fix things. Reddit user u/ramenporn, who claimed to be a Facebook employee working on bringing the social network back from the dead, reported, before he deleted his account and his messages: "DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC). There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures." Ramenporn also stated that it wasn't an attack, but a mistaken configuration change made via a web interface. Both BGP and DNS are down, the "connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally." Technicians on site don't know how to do that and senior network administrators aren't on site. It seems that it will all be down for a couple of more hours before the issue is resolved.

Wondering if upgrading to Windows 11 will boost your gaming experience? We can’t give you a straightforward answer, sadly. But we can take you through the tweaks you can expect if you have all the right requirements and help you make a final decision.

Is Windows 11 good for gaming?

Essentially, the answer to this question is yes. Microsoft has definitely added a bunch of enhancements and features to its latest OS to give gamers the best possible experience. However, you have to keep in mind that this may not work out smoothly for every single user.

Whether you’ll be able to fully take advantage of the Windows 11 gaming features really depends on your setup. As expected, Windows 11 has more demanding system requirements than its predecessor.

So, unless your hardware can run the new OS comfortably, you might not be able to make the most of all these gaming perks. In that case, we recommend you first upgrade your hardware and then make the switch. Be prepared to be a little surprised by a few other interesting changes in comparison to Windows 10, though!

For some of the new gaming features to work, it’ll also be necessary for you to have an NVMe SSD and an HDR-compatible monitor. So let’s take a look at 4 big improvements you can expect if your setup is compatible.

Gaming enhancements on Windows 11

1. Enjoy faster loading speed with DirectStorage

For this powerful feature to work, you need a compatible graphics card and, as stated before, an NVMe SSD. It’s also important for your GPU to support the DirectX 12 graphics API at least. And since we’re on that subject, you’ll be happy to know that Windows 11 has also introduced a new version of the API called DirectX 12 Ultimate. 

Now, what does DirectStorage do? It’s a new feature designed to make full use of the speedy storage of NVMe SSDs. It also transfers game data directly onto the graphics card, lightening the load on your CPU. Normally the CPU would have to decompress the data first, but DirectStorage helps bypass this. That’s how loading times are reduced and games run more smoothly.

2. Fully immerse yourself through Game Mode

Windows 11’s Game Mode is certainly a welcomed addition. When you turn on Game Mode, usage of background apps that aren’t essential to your game is reduced. This results in the game you’re running becoming a priority process. This way, it uses your hardware and system resources to the max. Ultimately, the Game Mode means less lag and higher frame rates so you can play undisturbed and fully enjoy your gaming session.

3. Vibrant visual experience thanks to AutoHDR

For this one you’ll absolutely need an HDR-compatible monitor. Basically, HDR (High Dynamic Range) means a wider range of contrasts and colors that can be displayed on a monitor.

Windows 10 has an HDR feature, but you have to turn it on and off manually (“Use HDR”). Plus, users have reported that, if left on, it results in an unappealing appearance of content other than movies and games. 

Windows 11 fixes that problem with its AutoHDR feature. Toggling it results in the system automatically adjusting the color contrast, balance and brightness based on what you’re currently looking at. For gamers, this means vivid imagery in every single game, resulting in a supreme visual experience. You can check out Microsoft’s own video showcasing the power of AutoHDR.

Aside from AutoHDR, another way Windows 11 improves the visual aspect is through its support for refresh rates of up to 360Hz.

4. Xbox Game Pass & Game Bar

It’s no secret that Microsoft wants to integrate Windows and Xbox. We’ve seen some attempts with Windows 10, but they’re pretty wonky compared to the new OS.

Windows 11’s built-in Xbox Game Bar enables quite a few options all gamers desire. You can take screenshots and videos of your game and send them, for starters. Furthermore, you can use it to see audio settings and monitor your PC’s performance without having to leave the game or open the Task Manager.

Widgets are also a really cool part of the Game Bar. You can choose from a wide variety of widgets, such as Xbox Achievements, Spotify, Gallery, Xbox Social and more. 

Moreover, the Xbox Game Pass has been streamlined on Windows 11. Game Pass is a subscription service that unlocks hundreds of awesome games and supports cloud streaming. Do keep in mind that the games are only unlocked for a certain period of time, as the selection rotates once in a while.

What can you do for a better gaming experience?

Windows 11 does offer tweaks that require zero input from you. However, there are a few things you can do manually to get even more out of your new OS while gaming.

• Turn off enhanced pointer precision. Most games enhance precision by default, so having this feature on might interfere with that.
• Make sure to select your high performance graphics card for each game. Go to Settings > Gaming > Game Mode and tap ‘Graphics’ from the ‘Related settings’ menu. Find the game you want to adjust, click on ‘Options’ and choose your high performance graphics card to be the default setting. While there, you can also turn on ‘Hardware-accelerated GPU scheduling’ at the top.
• Disable unnecessary apps and programs. As long as they aren’t essential to running your game, they might take up valuable system resources, so disable them to make space for your gaming requirements.
• Check for pending updates and install them. It’s well-known that out-of-date software causes bugs, latency and crashes. The same goes for your GPU drivers.
• Use the High-performance power plan (Control Panel > Power Options > Additional plans) to maximize the use of resources for the best possible performance.

Summary

Windows 11 has done quite a bit for avid gamers. We hope your setup is compatible with all these new features and you can experience these enhancements ASAP!

If you suddenly encounter an error message saying, “ File Record Segment is Unreadable ” on a blue screen while booting your PC, it means that your hard drive is in an error state. This particular blue screen of death error might have a lot of bad sectors or might have reached its end. The workarounds you can try to resolve the issue is by locating the bad sectors or checking your hard drive for any discrepancies in the mapping and fix them. Follow the detailed instructions laid out below for these workarounds.

Option 1 – Try to check for any bad sectors and wrong configurations in your hard drive

The first thing you have to check is the boot files on your PC. As you know, your PC boots from these files and if there is anything wrong with any one of them or if one of them ends up getting corrupted, you will most likely see the blue screen of death error or a prompt with an error message saying, “File record segment is unreadable”. According to some users who reported this issue, new hard drives aren’t exempted from this error. That’s why it is recommended that you carry out this solution no matter what kind of scenario you are in. You will have to launch the Command Prompt in recovery mode and see if you can fix the problem by executing the check disk commands.

• Upon booting, restart your PC and tap F11 to go to the recovery environment then select Troubleshoot.
• Next, click Advanced from the given options and select Command Prompt.
• After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them and if you have installed Windows to some different directory, you must replace “C” with the name of the drive you’ve installed Windows with.
• chkdsk C: /r /x
• chkdsk C: /f

Note: The Chkdsk function might take a while before it finishes its operations so you need to be patient and wait until the entire process is completed. And depending on the situation, it might even take a day at most so patience is really the key here.

Option 2 – Try connecting the hard drive to a different computer

If option 1 didn’t work for you and you’re still seeing the error, you can try connecting the hard drive to a different computer and then copy the data first. Make it a priority to salvage the data just in case the hard drive won’t make it in the future. After replicating your hard drive, you can then try running the chkdsk commands that are listed in option 1 above in the new computer you’re connecting your hard drive to and make sure that you key in the correct drive letter that’s assigned to the hard drive you’re using. After executing the chkdsk commands, plug your hard drive back into the previous computer and then check if you can now boot it without any issues.

Option 4 – Replace the faulty hard drive

If none of the options provided above really worked out then maybe it’s time to consider getting a replacement for your hard drive. In about 50% of the cases about this error, some unfortunate users were left with no choice but to replace the hard drive since the problem is with the hard drive itself. Hard drives have a complex running mechanism which includes a head and the disk that rotates accordingly so you can check if the cables connected to the hard drive are connected properly and if it is in a correct position or not. In addition, you also have to make sure that the SATA adapters where the hard drive is connected are working properly. If the drive is showing problems in the I/O operation, there is little chance for you to use it as a normal hard drive. If the hard drive is in warranty, get it checked and replace it. If not, you might consider taking it to the service center for the specialists to take a look into it.

Kernel32.dll Error - What is it?

To understand Kernel32.dll error properly, here’s what you need to know first: in the Windows operating system, the system32 directory plays a vital role. Inside this directory, there is an element called Kernel32.dll. A DLL (dynamic link library) is a library that contains codes and data that are used by more than one program at the same time. The role of the Kernel32.dll file is to handle memory management and I/O (input and output) operations. Malfunctioning of this file results in a Kernel32.dll error message which leads to program or application failure.

Error Causes

Kernel32.dll files can be attributed to several reasons like:

• Missing or damaged Kernel32.dll files
• Registry corruption
• .Dll files misconfiguration if programs are installed or uninstalled.
• Viral infection or malware attack

It is advisable to repair the Kernel32.dll error immediately to avoid inconvenience and serious computer damages like program lockouts, system failure, freeze, and crash.

Further Information and Manual Repair

All causes for the Kernel32.dll error are linked with the registry. The registry is the major database of your system that stores all the activities you perform on your system. It saves both important data and unnecessary files in the RAM (Random Access Memory) including the junk files, temporary internet files, and obsolete files such as files of the deleted/uninstalled programs. These files accumulate a lot of memory space. It leads to disk fragmentation, data overload, missing and damaged DLL files, and eventually registry corruption. Other reasons for registry issues that trigger Kernel32.dll errors on your system could be malicious software like viruses, adware, and malware. These also corrupt the registry and damaged DLL files.

Kernel32.dll Error Solutions

There are two ways to resolve the Kernel32.dll error on your PC, one is to install two separate tools registry cleaner and an antivirus and run them individually to scan your system and repair it. This option is time-consuming and besides if antivirus software is notorious for slowing down systems. So by downloading a separate antivirus you may have to sacrifice your system’s speed.

When clean Windows is installed or when you place new hardware in your computer usually Windows itself detects the device and installs its driver. The question that comes now is, do you keep that driver or do you install the manufacturer's one. In order to answer this question let's analyze what is difference between the two drivers and other factors which could influence your decision.

Difference between drivers

First of all, know that drivers Windows installs are also drivers from the device manufacturer which have gone through Microsoft quality control in order to be included in Windows itself. Now naturally question which occurs, what is the difference, well answer to that would be this: in Windows, you have stripped down driver, just a driver in order for Windows to know what device is plugged and how to use it, meaning that for example if you install printer device, you will be able to print documents and Windows will know it is a printer but ... You will not get the control panel for that printer where you can adjust the printer itself and all of its features like let's say paperweight, etc. So if you need these kinds of features in that case it would be better to install a complete driver suite from the manufacturer and get the whole package. Windows will recognize the RAZER mouse for example but you will not be able to change its colors of program custom buttons on it until you install RAZER drivers. One more important thing to note is that drivers which are in Windows are less updated than drivers from the manufacturer's site. That being said, if you prefer and want to have the latest drivers you will prefer to get them again from the manufacturer.

Conclusion

So it seems that manufacturer's drivers are always in some form of advantage and that you will always want them and most of the time this is true, as a matter of fact, the only time I could think that you could use bare down Windows drivers is when new drivers update breaks something in Windows and device start behaving improperly. in this particular case, it is better to roll back to the previous Windows driver which has passed Microsoft quality control and is working for sure. In any other case, you are better off with the latest manufacturers drivers If you would like to read more helpful articles and tips about various software and hardware visit errortools.com daily.

Error 0X800F080C is tied to corrupted system files and .NET framework issues. In this article, we will focus on how to fix it starting first with .NET fixes and then moving to system-related ones. Follow the guide step by step so you can fix this error fast and easily.

.NET issues

As previously stated 0X800F080C error can occur due to issues with .NET framework, 3.5 framework to be more precise and there are two ways we can fix this error. Follow the guide below as presented:

1. Install .NET 3.5 framework from Windows features

   First thing is to try and install the framework from Window features itself. Sometimes installation and activation of .NET 3.5 in other ways can result in this error. To install it do the following: Press ⊞ WINDOWS + R to open the run dialog Inside run type in appwiz.cpl and press ENTER to open up the Programs and Features menu Inside the Programs and Features menu click on Turn Windows features on or off. Check the box associated with .NET Framework 3.5 (this package includes .NET 2.0 and 3.0) Press OK Click on YES and wait for the package to be installed then reboot your PC

2. Run the .NET Repair Tool

   If the previous step was not successful or you already had .NET 3.5 installed then run the troubleshooter in order to fix issues. Go to the official Microsoft .NET framework repair tool website here and download it. Once downloaded install the tool and follow onscreen instructions.

Corrupted system files

If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

1. Run SFC scan

   SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) In command prompt type SFC /SCANNOW and press ENTER Wait for the process to finish, do not interrupt it and once it is done, restart your computer

2. Run DISM scan

   DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER. Leave scan to finish and reboot your PC
