A required device isn’t connected

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 1 – Apply some registry tweak

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.

PrintNightmare vulnerability has been a struggling issue for Microsoft in the past weeks, each time it seems to be addressed and fixed something new popped up and it still had issues. Microsoft finally addressed the issue but with a price. The default behavior of Point and Print is changed. From this fix onward, the Point and Print driver installation and update behavior will require administrator privileges, which should prevent the exploit to the Windows Print Spooler that could be used by malicious individuals to gain administrative privileges in Windows. The drawback of this fix from Microsoft is that non-elevated users may have difficulty adding or updating printers. Microsoft feels that the security risks caused by PrintNightmare are worth the tradeoff, though. If you really want to let non-elevated users add printers, you can follow the instructions in this Microsoft Support article to disable this mitigation with a registry key. However, doing so will expose you to this known vulnerability and isn’t recommend.

Microsoft has presented its next version of their flagship product, Windows 11, and feelings are divided among users. Some users like it very much and eager to upgrade, some do not like the graphic overhaul it went through, but overall I think Microsoft has done a good job with it. Here in this article, we will discuss some of the new features which Windows brings to the table, well at least ones that were showed, I am sure there are plenty more which we will see once OS has been released.

New Start menu

One of the first things that everyone saw when Microsoft has unveiled Windows 11 is its Start menu. Funny enough this is what has caused most of the divide among users, some find it interesting, and some do not like it. Truth is, it is different, and it is centered in the middle instead of the lower left part of the screen. It has been confirmed however that the Start menu can be moved to any part of the screen so if you want, you could place it on the lower left as it has always been. Live tiles do not longer exist in the Start menu, instead, we have styled simple icons.

Windows 11 Snap controls are great

If you have used the cascade option in previous Windows versions then it is most likely that you will like the new Snap controls. You can quickly snap windows side by side, or arrange them in sections on your desktop just by hovering over maximize button on the title bar.

Windows 11 File Explorer

File explorer has gone through some visual and design changes, the ribbon on top has been completely removed and replaced with a header-like feature with a slick and clean design. The header contains a nice organized and designed single row of icons like cut, paste, copy, rename, delete, and new folder icons.

Settings app ovberhaul

The settings app also has gone through visual and design changes. It has a new design that is very visually appealing and navigation has been simplified and more organized. Finding the right and desired setting is much faster and clearer now.

Widget tab makes comeback in Windows 11

Yes, widgets are back but not like you remember them. Instead of being all-time present at your desktop like once they used to be, now there is a button on the taskbar which brings the widget bar up that contains desired widgets. This way they are easily accessible and do not clutter desktops. So far we have weather, news, calendar, and stocks widget but we will see how development on these goes. I expect to have community-made widgets like in old days for all of our needs.

XBOX app

The new Xbox app is now integrated into Windows 11, offering quick access to Xbox Game Pass games, the social parts of the Xbox network, and the Xbox store.

Security and TPM 2.0 in Windows 11

As widely known by now Windows 11 will require you to have a TPM 2.0 module capable CPU in order to install it. This system requirement has caused a lot of controversies but essentially it seems that MS's goal is to protect your personal data by using this module. The upside of course is that your data will be protected much more than in previous Windows versions, the downside, of course, will be that you will need newer hardware to run OS on it. and that is essentially it, keep on tuned on more Windows 11 information and overall articles tied to PC and technology here at errortools.com
