Recently, a lot of users reported having an issue with Windows Update. According to these users, they got an error message saying, “Windows Update components must be repaired” after they run the Windows Update troubleshooter. So if you are also facing this issue then you’ve come to the right place as this post will guide you in fixing this problem. There are various suggestions you can check out to fix this problem – you can try running the Windows Update troubleshooter again but this time, in a Clean Boot State or you could also run System File Checker or the DISM tool to repair corrupted Windows Update files or reset the Windows Update components. For more information, refer to the given options below.

Option 1 – Run the Windows Update troubleshooter in a Clean Boot State

Repairing the “Windows Update components must be repaired” error is not that complicated. One of the things you can try is to run the Windows Update troubleshooter again but this time, in a Clean Boot State. Refer to the steps below to get started.

• 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 run the Windows Update troubleshooter again and see if the error is fixed or not.

Option 2 – Try to run System File Checker

If the Windows Update troubleshooter still failed to fix the problem, you can run System File Checker instead. It 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.

Option 3 – 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.

Note: If it happens that the Windows Update client is broken, you need to run the following command to repair it then restart your PC and click on Update once again.

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 4 – Delete the contents in the Software Distribution folder and Catroot2 folder

You can also delete the contents in both the Software Distribution and Catroot2 folders as it could potentially fix the “Windows Update components must be repaired” error.

• 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.

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.

Hello and welcome to errortools articles. Today we will talk about some great and awesome tips and tricks for the command prompt. Commands which can make your life easier and your workday more pleasant. That being said let's dive in right into muddy waters and swim out with new knowledge.

Tip 1: Read Motherboard information

There are a lot of reasons why you would like to read information from your motherboard, maybe you would like to upgrade your BIOS, perhaps you would like to know the serial number, maybe even the version number. Well, you can, type the following code into the command prompt and you will receive all information about your motherboard.

wmic baseboard get product,version,serialnumber,product

Tip 2: Copy command output to clipboard

Getting information from the command prompt to a word processor, into an email or any other medium can be somewhat troublesome, usually, people tend to screenshot or write from a command prompt into another destination, which could induce errors, and let's be honest, it is not practical. You can copy command output directly into the clipboard ready for pasting it anywhere with | clip. So for example if you would like to paste the directory structure of your c drive command would look like: dir c: | clip, now output would be placed into the clipboard ready to be pasted anywhere needed.

Tip 3: Erase data permanently

When you delete data on your hard drive, what really happens is that files are marked with a marker which marks that space for new data writing, but the data itself is still present and can be brought back. This sometimes could impose problems but if you would type: cipher /w:c Windows will write random data over each marked file deleting it forever without means to be brought back.

Tip 4: Manage your IP address

If you would like to play with your IP address and do fancy stuff with it do the following: ipconfig /release to release your IP address ipconfig /renew to renew your IP address ipconfig /flushdns to flush down DNS information and enjoy a new browsing start.

Tip 5: Check to see are packets reaching the desired location

You installed a new LAN printer, or a new switch, maybe you want to check if your new site is up and running. Use ping destination in order to see if TCP packets are reaching desired information, you can use it with a specific address like ping 192.168.1.1 or you can type a web address, for example, ping google.com and see if a connection can be established.

Tip 6: Get information about a specific command

So you learned some command prompt commands, but you do not know all of their configuration or switches? No worries, just type command/? to get a list of available switches for it. For example ipconfig/? will write you a list of available switches for ipconfig command.

Tip 7: Link and execute multiple commands one after another.

Let us say that for example, you would like to copy files into a different folder, then rename some and delete others and you need to do a couple of times. Instead of writing command after command once each one is finished link them with && and they will execute one after another.

Tip 8: Scan and repair files.

In order to scan files and repair broke or corrupted ones write in the command prompt: sfc /scannow. Please know that this command can take a long time since it is solely dependant on the number of files, their size, and the power of the computer.

Tip 9: Manage and configure your computer energy

Command powercfg will let you manage and see the power configuration of your computer. Just write powercfg/? and see what you need and want to change or get information about.

Tip 10: Associate files with applications

Windows already has some file associations defined, and some applications take over some type of files but if you want to take control into your own hand use assoc command. For example assoc.txt= "APPLICATION NAME" will associate txt files with the provided application.

Tip 11: Hide files and folder.

Do you have some folder or file with information that you do not want to be seen when someone opens file explorer? Use attrib +h <name of file> and hide file or attrib +h /D <folder name> to hide folder.

Tip 12: Get a list of installed computer drivers

Want to know which drivers are installed in your system? Use driverquery and take a look.

Tip 13: Find and locate shared folders

have you shared a folder but forgot which one and where? Do not bang your head on the wall, we have a simple solution for you. just type in command prompt net share and see everything.

Tip 14: Run commands as an administrator

You do not have administrator privileges? Do you want to bypass common blockades?

runas /user:yourdomainadministrator command

That is all that we have for you today, I certainly hope you have found something useful here and that we have managed to teach you some valuable things.

Microsoft will soon offer 4 CPU computer specifically aimed at developers and its name is Volterra. The machine as stated will come with 4 processors but the strange thing is that they will be ARM-based instead of x86.

CEO of Microsoft, mister Satya Nadella has introduced the product and Microsoft has released a youtube video promoting it.

https://youtu.be/yICVNta8jMU

The computer system will have Qualcomm's NPU or built-in neural processing unit to use AI's power to help developers write and produce better and faster code. The sad news is that besides processors used there is no other information on other components that will go into this system.

As seen in the video, the computer reminds me a lot of the apple MAC mini with its size and design, and as stated it is made from recycled plastic which in our opinion will bring the price under $1000.

Microsoft has not provided an official price tag for Volterra, but our hope is that it will be more affordable than building your own development PC. Also, there was nothing said about computer availability, we suspect that the selling model will be typical Microsoft one with first models available only in the USA and moving forward slowly opening it to other markets.

Volterra specifications

As previously said nothing except the number of CPUs and their type has been officially said but we managed to get some information about some other specific things not including its inside components.

The unit will have a fan inside of it for cooling purposes and better performance and that is what was officially stated by Microsoft. On the outside, it is known that the computer will have three USB-A ports, a mini DisplayPort, and an ethernet input. All of these will be positioned on the back of the device, on its left side there will be two USB-C ports.

The unit itself will be running on Windows 11 but it was not disclosed anything about the version, we presume since this is a model aimed for professional use that it will come with Windows 11 PRO version.

Currently available tools for ARM

Since this product is aimed at developers logically support for developing software is a must-have and at the time of this writing software that will come and that will run on Volterra is:

• Visual Studio 2022
• Visual Studio Code
• Visual C++
• Modern .NET 6 & JAVA
• Classic .NET
• Windows Terminal
• Windows Subsystem for Android
• Windows Subsystem for Linux

Conclusion

Once MAC studio has been released it showed that specific builds have their audience and can be sold for less of a price than full-fledged custom-made workstations. There is no doubt that Microsoft Volterra will find its audience but will that be enough to have more versions of this compact computer only time will tell.

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

AI and neural networks are more and more being used in all parts of our lives. From face detections to deep fakes it is both amusing and frightening to watch at the same time. From some really bad uses of neural networks and AI overall, looking at you deep fakes, upscaling videos or images are mostly harmless pieces of work not harming anyone. There is one cool YouTube channel, well there are more but this one seems to have most of the videos on it and if I am wrong I apologize. https://www.youtube.com/channel/UC33rC3GO1UZFAkMcCCwjyWg So upscale is like previously mentioned a YouTube channel that hosts old game trailers and into videos but in full 4K or 8K video resolution, fully upscaled using neural networks. There are some videos that are not maybe top-notch but the large quantity of them is pretty well upscaled and they do indeed look great. So if you have some time and want that old nostalgia fix, go and check it out. You might find something that will bring that old you out and you might even drop a smile or two remembering old good days, I know I have.
