Fix Windows Updates Error code 0x80246007
Downloading Windows Updates does not always go smoothly as you can encounter several issues like the “Some updates did not finish downloading, We will keep trying, Error code 0x80246007” error. In fact, this error can also occur on other Windows applications like OneNote. According to security experts, this error happens for many reasons. For one, it could be that the Windows Update database is corrupted. It could also be that there is another process that’s in conflict with the Windows Update components or there might be some issue with the Background Intelligent Transfer Service (BITS). Whichever the cause may be, you can fix it by following the solutions given below.

Option 1 – Delete the contents in the Temporary folder

You can also try deleting the contents in the Temporary folder – all the downloaded, pending, or failed Windows 10 updates. You can do that using the simple and easy steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “%temp%” in the field and press Enter to open the Temporary folder.
  • After that, select all the folders and files within the Temp folder and delete all of them.

Option 2 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like Error code 0x80246007. 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. After that, follow the next on-screen instructions and you should be good to go.

Option 3 – Try renaming or removing the pending .xml file

The problem might be due to some pending .xml file so you need to rename or remove it. To do so, just go to C:/Windows/WinSxS folder. From there, look for a pending .xml file – you can either rename it or delete it. This will allow the Windows Update to delete any pending tasks and build a new and fresh update check.

Option 4 – Restart the Background Intelligent Transfer Service (BITS)

The Background Intelligent Transfer Service or BITS is a part of the Windows Update service that manages the background download of Windows Update, as well as scans for new updates and so on. Thus, if your Windows Update fails a couple of times, you might want to restart BITS. For you to do that, make sure that you have admin privileges.
  • Press the Win + R keys to open the Run dialog box.
  • Then type “msc” in the field and hit Enter to open Services.
  • After opening Services, look for the Background Intelligent Transfer Service from the list of services and then double click on it to open Properties.
  • Next, set the Startup type to Manual and click on the Start button. If it doesn’t help, you can try setting it to Automatic (Delayed) and then reboot your PC.

Option 5 – Run the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.
  • Open the Command Prompt with admin privileges.
  • Then type in the following commands and make sure to hit Enter right after you type each one of them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • exe /Online /Cleanup-image /Restorehealth
  • Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 6 – Delete the files from the Software Distribution folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.
  • 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 start cryptSvc net start bits net start msiserver
  • After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
  • Next, go 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.

Option 7 – Reset the Catroot2 folder

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:
  • Type each one of the following commands.
net start wuauserv net start cryptSvc net start bits net start msiserver
  • After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Intel i9 Alder Lake better than AMD Ryzen 9
Alder LakeIf we are to believe news from Intel, new series of processors based on Alder Lake architecture are about to be released somewhere in October. Alder Lake is the 12th Generation Core of Intel processors and it is meant to have all advantages of the current CPU structure. I9 is aimed to pack a punch against its competitors with technology including eight high-performance Golden Cove cores (P-cores) with Hyper-Threading and eight energy-efficient Goldmont (E-cores) equipped with a 30MB L3 cache and operating at high clock speeds. During the benchmark test, the new CPU outperformed all of Intel’s previous Rocket Lake structure processors which is logically expected but the big surprise came from results that indicate better performance than Apple’s new M1 processor even in single-threaded performance which is supposed to be best in that field. Another surprise was really beating AMD Ryzen 9 in each field. If we take into account that i9 has 16 cores in total and can process 24 threads against Ryzen 9 with 16 Cores and 32 threads this is an impressive feature. Now truth to be told Alder lake has massive L3 cache and microarchitectural advantages and consumes much more power but the results of performance are high. Also, note that this early CPU is not really a mass production one and maybe some things will still change but early results are very satisfactory. We will see what will price tag be since in this age of shortage and competition that will also play a big role in its overall success. Speaking of competition I eagerly await AMD’s response to this, in any way it seems that the CPU market is for some turbulence which is always a good thing for the final customer and I welcome it.

How to Fix Entry Point not Found Dll Errors

What is ‘Entry Point not found dll’ Error?

Entry Point not found dll errors are common in Windows PC. These errors indicate poor PC maintenance. An entry point is basically the memory address inside the dynamic link library. It contains the call being made. A dynamic link library on the other hand is a collection of small programs which use and request this call to run and load programs successfully on your PC. However, when this process is unable to be executed successfully, you come across ‘entry point not found dll’ error messages.

Solution

Restoro box imageError Causes

Generally speaking, some of the typical causes of ‘entry point not found dll’ errors are:
  • Missing, corrupted, and damaged dll files
  • Registry overloaded with invalid entries
  • Disk fragmentation
  • Viral infection
It is advisable to resolve these ‘entry point not found dll’ errors on your PC immediately because dll errors can cause you a great deal of inconvenience as you may be locked out and unable to access your desired programs. Furthermore, if dll errors are left unresolved, such errors can expose your PC to serious threats like system failure, system damage, corruption, and crash.

Further Information and Manual Repair

Though ‘entry point not found dll’ errors are critical errors but the good news is that these can be easily resolved. To fix dll errors on your PC, you don’t always have to hire a professional technician or be a computer programmer yourself. Here are some of the best DIY (do it yourself) ways to resolve ‘entry point not found dll’ errors on your system:

1. Reinstall the Deleted Program

This method to resolve ‘entry point not found dll’ error code is very basic. It is advisable to uninstall and then reinstall the deleted program to retrieve the missing or deleted dll files. Here’s why: dll files are shared files. There are multiple programs on your PC that may be using one type of dll file to load. Now when you uninstall a program that you no more need on your PC, chances are that it may also delete that particular dll file. And when this happens the other programs supported by the deleted dll file are unable to load. Therefore, in such an event the best way to retrieve the missing dll file is to uninstall the program that displays the errors message and then reinstall it. This will help you restore the missing dll file and run the program successfully.

2. Install an Antivirus and a Registry Cleaner

As mentioned above, ‘entry point not found dll’ errors indicate poor PC maintenance. If you don’t maintain your system, the registry overloads with bad and invalid entries, redundant and obsolete files, junk files and cookies. These files acquire a lot of space which damages dll files and the registry. Furthermore, due to data volume overload and less storage space, files are then saved in different places. This is also known as disk fragmentation. When these files are called, it takes a lot of time for the disk to consolidate fragmented data and execute the function successfully. To resolve these issues, you need to clean and restore the registry. Though this can be done manually it may be slightly complicated and time consuming therefore it is advisable to install and run a registry cleaner.

Restoro.

In addition to this, due to poor PC maintenance, viruses and malware can also enter your system unknowingly through file downloads and phishing emails. These can also damage dll files. To remove viruses and malware from your PC it is important to run an anti-virus. Instead of downloading both tools separately on your system, we recommend Restoro.

Fix Folder Redirection Failed in Windows
If you got an error message saying, “Folder Redirection Failed, Failed to build the list of regular subfolders, Access is Denied” after you configured a new Group Policy Object or GPO which redirects User folders to a new network share or when you click on Reset default location under the Windows File Explorer or Folder Options, then you’ve come to the right place as this post will show you how to resolve this kind of error on your Windows 10 computer. Follow the given options below carefully to fix the “Folder Redirection Failed” error.

Option 1 – Take Ownership of the folder

If you are not able to access the folder could be one of the reasons why you’re getting the “Folder Redirection Failed” error and so you need to take ownership of the folder to resolve the problem. Before you proceed, make sure that your account is an admin account.
  • First, locate the concerned folder and right-click on it then select Properties.
  • Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
  • After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
  • Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
  • Now edit the permission to Full Control for “Everyone”.
  • Click OK to save the changes made and then exit.

Option 2 – Try to add Authenticated Users or Domain Computers

Make sure that the Folder Redirection group policy removal option is set to “Redirect the folder back to the user profile location when the policy is removed” when using the Folder Redirection. After that, you have to add Authenticated Users group with the “Read” permissions on the Group Policy Objects or GPOs. And if the Domain computers are part of the group of “Authenticated Users”. Note that by default, the “Authenticated Users” have these permissions on any new Group Policy Objects or GPOs. Once again, you have to add just “Read” permissions and not “Apply Group Policy” for “Authenticated Users”. Furthermore, to fix the “Failed to build the list of regular subfolders” errors, here are some options that could help.

Option a – Try to clear disk space

You might have to check if your disk is running out of space because if it is, then it will fail to create a list abruptly. And so you need to free up some disk space. You can either check on the files manually especially if you tend to keep your files at random places in your disk drive.

Option b – Find the Target route

You need to find the target route of the folder and then restore it if you are getting the “Failed to build the list of regular subdirectories” when you try to relocate the folder to the original location.

Option c – Try to change Ownership/Reset Defaults for all the User folders

If the “Failed to build the list of regular subdirectories” error pops up when you are trying to move a large number of files from one location to another, then you need to change the ownership of the folders as pointed out earlier.

How to Fix Windows 10 Upgrade Compare Exchange128 Error Message

Compare Exchange128 error – What is it

Some Windows 7 and Windows 8.1 users reported experiencing a Compare Exchange128 error when trying to upgrade to Windows 10. The error reads, “You can’t install Windows 10 because your processor doesn’t support CompareExchange128”. In order to upgrade to Windows 10 (64-bit), the CMPXCHG16B instruction must be present. If you receive this error, this mostly means that your CPU doesn’t have the CMPXCHG16B instruction.

Solution

Restoro box imageError Causes

The CompareExchange128 error normally occurs due to two possible reasons:

  • CPU lacks CMPXCHG16b Instruction
  • Old & Outdated BIOS – Even if your CPU has the CMPXCHG16b instruction, the CompareExchange128 issue can still occur if you have an older BIOS.

Further Information and Manual Repair

One main requirement to upgrade to Windows 10 is for your CPU to have the CMPXCHG16b instruction. You also need the right BIOS version to guarantee a smooth installation. See below on how to manually fix this issue.

NOTE: If you don’t feel confident using the manual methods listed below, it’s highly advisable to get help from an expert technician. If you don’t know someone, you can also use an automated tool to fix this.

Before performing any fixes, try to determine first if the cause of the error is due to your CPU lacking the CMPXCHG16b instruction. You can use a CPU Info tool that provides complete details about your processor, memory, and motherboard. If you’re looking for more in-depth information, you might also try command-line utilities. But, the safest and easiest way to check this is by simply searching online. Try using the search query: <CPU Model> CMPXCHG16b

Method 1 – Update your BIOS

This method will download the latest BIOS from your motherboard’s manufacturer. This makes sure your CPU has the CMPXCHG16b instruction needed to complete the Windows 10 64-bit installation. To update your computer’s BIOS, complete the following steps:

  1. Determine first the current BIOS you have on your computer. Open System Information Windows app and type msinfo32 in the search bar. The BIOS version will appear under the processor speed. Record it somewhere.
  1. Go to the support page of your motherboard’s manufacturer. Find if there’s any update on the BIOS that you’re currently using. If you find one, download the BIOS update file available. Make sure that you’re looking into the right model and you download all the necessary documentation. Otherwise, the BIOS update might not work.
  1. Update your BIOS. Most BIOS update steps are straightforward. Just make sure to follow the steps provided.

Method 2 – Install Windows 10 32-bit version

If updating the BIOS doesn’t work, what you can do is install a 32-bit version of Windows 10 instead of the 64-bit version. Here’s how to do this:

  1. Download and install the 32-bit version of Windows you currently have. If you have a Windows 7 64-bit version, get the 32-bit version of Windows 7. The same goes for Windows 8.1.
