Cannot find a system image on this computer

If you have set a static IP address manually in your Windows 10 computer and you encounter an error saying, “This operation failed as no adapter is in the state permissible for this operation”, then you won’t be able to connect to any network. Many users have reported that they were unable to connect to any network after they set their IP addresses manually and all they see is a red cross symbol on the network icon located at the left-hand side of the taskbar. And upon trying to release the IP configuration and renew the address using Command Prompt or Windows PowerShell, they are getting the error instead. Users also noted that their internet connection is fine since they were able to connect to their Wi-Fi connection on their mobile devices. However, they find it hard to connect to the internet using their PCs. To fix this issue, here are some possible fixes you can check out. Make sure to follow each one of the instructions carefully.

Option 1 – Try to run the Internet Connections troubleshooter

As you were not able to connect to your internet connection using your PC, you can try to run the Internet Connections troubleshooter as it might resolve the problem. Refer to the following steps to run this troubleshooter:

• Tap the Win + I keys to open Settings.
• After opening Settings, go to Update and Security.
• Next, navigate to the Troubleshoot pane and select the Internet Connections section and click the Run Troubleshooter button to get started.
• Wait until the troubleshooter is finished doing its job and then try connecting to your network again.

Option 2 – Try to perform Network Reset

As pointed out, the “This operation failed as no adapter is in the state permissible for this operation” error occurs due to the static IP you’ve set. Thus, to fix it, you can try to perform a Network Reset. This will reset the entire network configuration including your IP address. To perform Network Reset, follow these steps:

• Tap the Win + I keys to open Settings.
• From there, go to the Network and Internet section.
• Next, scroll down and look for “Network Reset” under the status pane.
• After that, click on Network Reset and then on Reset now to start resetting the network configuration. Once done, check if it is able to fix the error or not.

Option 3 – Try to update or rollback or uninstall the Network drivers

You might also want to update, roll back, or disable your Network drivers to fix the “This operation failed as no adapter is in the state permissible for this operation” error.

• 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.

Option 5 – Temporarily disable Firewall and third-party antivirus Firewall and antivirus programs are known to block files the instant it detects a threat to the system. However, there are some cases when it can also block a file even when it’s a safe one. Thus, your antivirus or firewall programs might be the reason why you can’t download anything on your Windows 10 computer. To isolate the issue, you need to temporarily disable both the Firewall and antivirus programs and then check if you can now download anything from the internet. Do not forget to enable them again as disabling them can leave your computer vulnerable to cyber threats.

One of the important processes in the Windows operating system is the Setting Synchronization or SettingSyncHost.exe. This process is the one responsible for synchronizing the settings of your computer with other devices. It is the one that replicates settings like OneDrive, Internet Explorer, wallpapers, and so on, to other systems. However, it has been known to cause high CPU usage in Windows 10 and there are times when it causes the system to freeze or system lags. So if you notice that the SettingSyncHost.exe process is causing high CPU usage in your computer, worry not for this post will guide you in fixing them. You have to be cautious when you notice high CPU usages caused by system processes since cybercriminals mostly set the names of viruses in a way that the system or the user won’t be able to identify them. Cyber crooks could name the virus and malware the same as one of the system processes like SettingSyncHost.exe to make it seem like it’s a legitimate process. Thus, you need to keep in mind that original system processes like the SettingSyncHost.exe file are located in the System32 folder. The original SettingSyncHost.exe file is located in the System32 folder. To check for the same, right-click on the troublesome process in the Task Manager and select Open file location. If the place is any other than the System32 folder, run a full system anti-virus scan on the system. The SettingSyncHost.exe causes high CPU usage when it gets stuck in the sync process and is not able to come out of the loop. To fix this problem, you need to follow the solutions offered below but before you proceed, make sure that you create a System Restore point first.

Option 2 – Close the Host process for setting synchronization

If the registry tweak didn’t work, you can try to close the host process for setting synchronization, especially if this process continues to hog resources. You can terminate this process by opening the Task Manager. From there, end the process or task of the host process. On the other hand, you can also turn off the Host process for synchronization by opening Settings > Accounts > Sync settings located in the left pane. After that, turn off the Sync setting.

Spending a large amount of time working or gaming in front of the computer can take a toll on your health. And as someone who indeed spends a large amount of time in front of the computer, I would like to share some insights about how can you be happy and healthy at the same time by incorporating some practices and habits.

Get good chair

This is first on the list because it matters the most. A proper sitting chair is essential for back health. If your budget allows it, do yourself a favor and get an anatomic sitting chair or gaming chair with lumbar support. It costs but it is worth it.

Learn to sit properly

As the important chair is, sitting properly is also as important as much. Your spine believe it or not is a very important part of your body and you need to take care of it. Sadly long periods of sitting sessions are bad for muscles around the spine that could reflect on the spine itself. Keep your back straight and keep your head not down nor up, place it in a position like when you are walking so the spine that is going from your head is in line with the spine on your back.

Stretch

By medical standards, each hour of sitting should be accompanied by a stretch session since sitting itself is placing too much pressure on certain muscles and blood circulation is lowered. Changing leg position and doing just a little stretch each hour can be really beneficial for your health in long run.

Take breaks

Yes, playing games is fun and most of the time we do not want to stop playing, especially if we are winning but taking breaks is essential for your personal health. Old saying goes that overdoing anything is bad and this applies true even to things that we do for pleasure and relaxation. Take periodic breaks to stretch, stand up and maybe even walk just a little.

Drink water

During long work hours or long gaming sessions, it is not uncommon that we are so focused on our activity that we forget to take our water intake. Approximately 2liters of water per day is needed for an adult person to function properly during that day and if you spend long times in front of a PC do not forget to drink water.

Do not neglect your daily tasks

As enjoyable as it is gaming can make us forget about our daily tasks, do not neglect your life and your tasks. Remember, gaming is only OK if it does not interfere with the daily things that you need to do. Do not postpone going for groceries because of gaming, do not switch shower for another level in the game. Do all of the things you must do first and then sit and game.

Take care of yourself mentally

Having mental health is as important as having a physical one. Playing games is fun, but playing games with someone is even better, do not forget to socialize and invite some friends so you can share some fun times together. Also, detach yourself from outcomes that will come because of gaming, this is very important for gamers that do a lot of PVP games and get annoyed and angry when they lose or when some other player is talking trash. Remember, gaming is for you to relax and enjoy, not to stress you.

Why combining hard drives with storage spaces? Ok, I will admit it, I am a modern digital hamster when it comes to digital goods. I like to collect stuff and more than anything else I like to have all of that at the tip of my fingers. And how digital goods grow in size themselves (movies on Blu-ray are like 50GB each) and the collection grows in size single hard drive is starting to be completely obsolete when it comes to storage. Sometimes we will need large storage for these kinds of personal collections, sometimes we will need it for work reasons. Whatever your reason might be Windows 10 is offering us a solution via Storage spaces. Storage spaces is an integral part of Windows and it is meant as a tool to provide you with a RAID environment without a RAID controller. Of course, combining multiple hard drives via storage paces instead of RAID will not be so fast or stable but for home use of storing a large quantity of data is perfectly enough. With Storage Spaces you will also have an option to reduce some space for increased security of data loss if by any chance one of your HDD fails.

How to Create a Storage Space

To create storage space in Windows, press ⊞ WINDOWS + R to open the run dialog. In the run box type in Control Panel and press ENTER In Control Panel find Storage Spaces and left-click on it. Once storage spaces open, left-click on Create a new pool and storage space Once you click on create new, you will be greeted with a list of hard drives you can use for this operation. Please note that all hard drives you choose will be completely erased and formatted and then assign a single drive letter. Click on Create pool. You will find yourself in new storage options where you can assign a drive letter, give storage space a name, etc.

Storage spaces types

One thing I would like to focus on here is resiliency type, when you expand the resiliency type drop-down menu you will see 4 options inside. Simple, Two-way mirror, Three-way mirrors, and Parity. Simple: If you choose Simple as an option, you will have maximum hard drive space but no resiliency at all, meaning that if by any chance any of your hard drives malfunction, you are losing your data from that drive completely. Two-way mirror: This option will save your data if one of your drives fails but you need at least 2 drives and storage space will be limited since some of it will be a safe backup option for the case of a drive failure. However if one of your drives fails, you can replace it in a second and keep on working as nothing happened. Three-way mirror: This option similar to the previous one will offer you safe data-keeping from a hard drive failure. this option will save your data even if 2 hard drives malfunction but it will require having 5 of them connected in order to be able to choose this option. Parity: Maybe the most popular option among people who want to have 2 or 3 drives merged but do not want to lose too much space of the two-way mirror option. It offers some protection and it does not take so much space as two-way does, let us say it is a kind of win-win situation.

Conclusion

I personally go for simple and have an important backup on optical drives but only for reason I could use more space, know that this way is requiring from me to always have a backup in optical media and that I will need to restore all of it back if even one HDD fails which could take time. But if this way is ok with you, go for it, you will have more space to use.
