Microsoft Windows 11 limitations surfacing
windows 11As more and more people get into insider preview of upcoming Windows 11 we will see more and more different takes and opinions on it. Generally speaking, the first wave was quite positive when it was previewed but how time is passing more and more limitations and frustration comes to the surface. Some of the limitation that is inside it, which have been confirmed by Microsoft itself includes features missing that we had in Windows 10 like moving the application to the taskbar in order to pin it, moving the file in the taskbar to open it in default application and some big annoyances like Windows opening widgets always in Edge no matter what is your default browser. Not being able to move the taskbar from the bottom is also one of many illogical things. There is not really a point in these missing features since they were working fine in Windows 10 and many users liked them since they could customize Windows more to their liking, now with this new look at limitations it reminds me personally much of apple macOS and I will be honest, I am not a big fan of that kind of thinking. If I wanted that kind of OS I would have gotten myself a MAC, not custom build PC, but hey, Linux is always a free alternative, and how Microsoft itself is pushing limitations and in my opinion bad design choices along with awful system requirements that might just be a case for a lot of users. I am really not sure what is logic behind these moves and I am sure they have their reasons but this time it seems that their take on the new OS is not resonating well with the overall user population, well at least what I have heard so far. Things of course can still be changed and made for the better and I would rather see release postponed and issues addressed than getting more system hogging and limited new OS that at its current state looks like reskinned Windows 10 with limitations.

Some Steam tips and tricks for easy life
steamSteam has cemented itself as the largest digital game shop in the World. First, release all the way back on September 12th, 2003, it was meant to be a standalone software client aimed to deliver updates to Valve’s games. It was soon expanded to include titles from third parties. The greatest Steam expansion and its popularity started in 2004 with the release of Half-life 2. Steam allowed prepurchased editions to be downloaded before the official release of the game making it available for play the moment it was officially out. Very soon after Steam gained its popularity, Valve has opened doors to other developers and offered them to use Steam as means for a digital distribution platform. Today it hosts over 30000 different game titles, not including DLC or applications. And how soon Valve’s steam deck is coming out soon we would like to share some great tips and tricks about Steam itself for easy everyday gaming.

Steam guard account security

Security of any of your accounts should be something that you really take seriously. So as always use a strong password for Steam but if you want an extra layer of security for it, and you should, use the Steam built-in feature: Guard Account Security. In order to activate Security Guard go to Steam>Settings>Account>Manage Steam Guard Account Security. Once enabled you will be able to use the Steam mobile application for special code when opening Steam or your email address.

Use Steam beta feature

Once a Steam account is created by default you will download and install the client. In the client, you will have the latest features available but there are more Steam features than default ones, beta features that can offer some improved and new functionality, and do not worry, they are stable and bug-free. I have been in Steam beta for years and not even once have I had any issues with the client itself but I have always had the latest features that will come to regular users later. To enable beta participation to go to Steam>Settings>Account, open the drop-down Beta participation menu, and choose Steam Beta Update. Confirm on OK and restart the Steam client. You will now get all the latest features first.

Manage your library via Collections

The collection is a neat idea for organizing your large game library into different collections or sections easily expanded and contracted for easier navigation and organization. To add the game to a collection just right-click on it and select Add To>New Collection, make a name for a collection like action, RPG, or whatever rocks your boat, and you are done. Once the collection is created other games can be added to it simply just by dragging it into the desired collection.

Make shelves

Shelves are ways to see your collections in the larger areas of the Steam clients. By clicking Add Shelf>Choose a Shelf, you can now add your collection to a shelf on the larger part of the client as a horizontal scrolling container with your chosen games. There are also some predefined shelves like All Games, Recent friend activity, and more.

Hide Game from Library

By right-clicking on a game and selecting Manage>Hide This Game you will remove the game from the active view of your Steam library. Note that the game will still be owned and a part of your library, you will just not be able to see it. This is a great feature when for example you have some things that came as a part of the game pack you are not really interested in when you have 2 different versions of the same game as for example standard and deluxe edition or just by simply not wanting to have game visible in the library. You can find a hidden game by typing its name in the search box and from there you can unhide it.

Play game soundtracks inside Steam

Some games offer you to purchase their soundtracks if you like music from them and some even include OST with a regular purchase. Steam lets you play these soundtracks and even lets you import your own music library folder into it in order to play all of your music inside the client itself. It has even options to automatically stop music playing once the game is run and you can make playlists as well. Your purchased game soundtracks are automatically included, the rest you will need to add by pointing Steam to the folder where you keep music in.

Configure gamepad

Inside Steam, you can configure your gamepad’s general settings, big picture settings, desktop settings, etc. Steam embraced the idea that many OC users these days own and play with gamepads so it has implemented configuration options inside it. To configure your pad go to Steam>Settings>Controller.

Use big picture Steam mode

Big picture mode is Steam's idea of making Steam an entertainment center. Once it is activated it switches from the application into full-screen mode aimed at large TV screens or monitors. You can easily navigate through it via gamepad, mouse, keyboard, or other devices. You have access to the store, your game library, etc. Same as your typical steam app but a little different. You can easily activate it via View> Big Picture Mode and see for yourself is this something you prefer over a standard application layout.

Enable Steam Cloud

Steam Cloud is a great feature that uses cloud storage to save your game progress meaning that you can easily switch to another PC, install games there and continue where you have left off. Many games support this feature instead of keeping saves locally and it is a great feature worth turning it ON. To turn and use Steam Cloud service go to Steam>Settings>Cloud>Enable Steam Cloud Synchronization. Just remember to check does game you are playing supports this option.

Share your Games via Family sharing

Family sharing is a Steam feature allowing you to share your game library with up to 5 accounts on up to 10 different devices. This is a great way to let other members of your family or even close friends enjoy some games you have or vice versa. They will get as well their own save games so you can sleep safe knowing that your progress can not be changed or hindered. Family sharing can be turned ON by logging into PC Steam client where you would like to share your library and navigate to Steam>Settings>Family and then clicking on Authorize Library Sharing On This Computer.

Refund a game

Sometimes the game is not the same as advertised, sometimes it will not work on your PC, sometimes hardware specifications are too high making the game unplayable, etc. For whatever reason, you might have Steam offers you a full game price refund if you wish to do so, you only need to meet 2 criteria, the game must have been purchased within 2 weeks period, older purchases cannot be refunded, and your game playtime must not be over 2 hours of game time. If you fit into this category all you need to do in order to get the full money back is going to Help>Steam Support, pick a recent game from the eligible list, and ask for a refund.

Gift a game

As you can buy gifts for your friends or loved ones in real life, Valve made sure you can do it in digital as well. Gifting game via Steam is simple and straightforward. Choose a game you wish to gift, go to your shopping cart and instead of clicking Purchase for myself, click on Purchase As a Gift, from there you will be taken to your friend list to choose to whom you would like to gift a game along with the option to write a little note to the receiver like happy birthday, enjoy or whatever.

Stream games in Steam itself

Although Steam is not there yet in streaming as Twitch or Facebook gaming is, there is an option to stream your game sessions on it. Click on Steam>Settings>Broadcast to make all adjustments and start streaming. You can also watch streams from your friend list and Steam is now broadcasting popular streams directly to its client if you want to watch it.

Take a game screenshot

By pressing F12, you can take a screenshot from any game and save it inside your Steam cloud library. You can change of course this default screenshot key via Settings>In-Game and if you would like to see your screenshots you can always do it under View Screenshot Library on a game’s page. That’s it, our Steam tips and tricks for easy and good gaming life, I hope to see you soon on errortools.com for your daily articles, tips, and tricks.

Fix The default gateway is not available Error
If you were having some problems with your internet connection and you tried to run the Internet Connections troubleshooter but it displays an error message instead that says, “The default gateway is not available”, read on as this post will show you what you can do to fix this error. The first thing you can do to fix this error is to restart your computer and then try to run the Internet Connections troubleshooter again. However, if you still see the same error message, then you might want to troubleshoot the problem further. You can try to install the Network driver or reinstall the Network adapter drivers. You could also verify the power saving mode or reset TCP/IP as well as disable the Firewall temporarily.

Option 1 – Try installing the Network driver

The very first thing you can do to resolve the error is to install the network driver. It is a common solution to this kind of problem and most users encounter it right after a fresh installation of Windows 10. So if you have done this, then you need to install the network driver so that the network adapters can start working. You can find the network driver in the motherboard CD. On the other hand, if you are using a laptop, you might have to use another computer or mobile to download the network driver from the manufacturer’s website.

Option 2 – Update the Network Adapter drivers

If the first option is not applicable to you since you already have network drivers in your computer, you might want to update the Network Adapter drivers by following these steps:
  • 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.
  • Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand them.
  • Then right-click on each one of the Network drivers and update them all.
  • Restart your PC and see if it helped in fixing the BSOD error.
Note: If updating the network drivers didn’t help in fixing the “Windows could not find a driver for your network adapter” error, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

You could also try to reinstall the network adapter driver, refer to these steps:

  • Open the Devices Manager from the Win X Menu.
  • Then locate the device drivers and right-click on them to open the Properties.
  • After that, switch to the Driver tab and click on the Uninstall Device button.
  • Follow the screen option to completely uninstall it.
  • Finally, restart your computer. It will just reinstall the device drivers automatically.

Option 3 – Try to verify power-saving mode

If you are using a Windows 10 laptop, then you should know that the Power Options panel plays an important role. So if you’re getting an error in your laptop, you have to check some settings that are related to the Power Saving mode. To do so, follow these steps:
  • Open Control Panel and go to Hardware and Sound and click on Power Options.
  • Next, click on the “Change plan settings” option of your selected plan and then click the “Change advanced power settings” option.
  • After that, you should see the Power Options window, and here, expand the Wireless Adapter Settings and Power Saving Mode.
  • Now make sure that the Maximum Performance option is selected. If it’s not, select it and save the changes you’ve made.

Option 4 – Try to reset the TCP/IP

As you know, the TCP/IP or the Internet Protocol is the most important thing if you want to use the internet on your computer. That’s why if it ends up getting corrupted, you need to reset the TCP/IP to fix the problem. To reset TCP/IP, refer to these steps:
  • In the Windows start the search, type “command prompt” and right-click on Command Prompt from the search results.
  • Then select the “Run as administrator” option to open Command Prompt with admin privileges.
  • After that, execute this command: netsh int ip reset resettcpip.txt
  • Once it’s done, exit Command Prompt and restart your computer and then check if the error is now fixed.

Option 5 – Temporarily disable Firewall

On the other hand, the error could also be due to the Firewall software installed on your computer. Thus, disabling them or any security software installed on your computer is always a good idea you can try when you’re not able to access the shared drive on your computer. There are times when you encounter problems like the error “The default gateway is not available” due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program and Windows Defender Firewall for the meantime and check if it fixes the error or not

If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:
  • KMODE EXCEPTION NOT HANDLED
  • PAGE FAULT IN A NONPAGED AREA
  • IRQL NOT LESS OR EQUAL
  • SYSTEM THREAD EXCEPTION NOT HANDLED (CMUSBDAC.sys)
In most cases, the CMUDA.sys file usually triggers the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Blue Screen error. Although this Blue Screen error may seem complicated, its workarounds are straightforward so you won’t have any problems in following them.

Option 1 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.
  • Open the Devices Manager from the Win X Menu.
  • After opening the Device Manager, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties. On the other hand, you can also look for sub-entries under Sound, video, and game controllers like the C-Media USB Audio Class
  • After that, switch to the Driver tab and click on the Uninstall Device button.
  • Follow the screen option to completely uninstall it.
  • Finally, restart your computer. It will just reinstall the device drivers automatically.
Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer. You can download the as C-Media USB Audio Class driver from the cmedia.com website.

Option 2 – Try to recreate the CMUDA.sys file

The first thing you can try is to recreate the CMUDA.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. Which is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.
  • Boot your Windows 10 PC in Safe Mode.
  • Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
  • From there, look for the file named sys and rename it to CMUDA.old.
Note: As you can see, the file’s extension has changed from .sys to .old.
  • Now restart your computer and check if the CMUDA.sys Blue Screen error is now fixed.

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

Running System Restore might also help in fixing Blue Screen errors related to the CMUDA.sys file.
  • Tap the Win + R keys to open the Run dialog box.
  • After that, type in “sysdm.cpl” in the field and tap Enter.

Keyboard shortcuts and hotkeys are not working
This post will guide you on what to do if your keyboard shortcuts or hotkeys are not working on your Windows 10 computer. A lot of users use hotkeys as they make things easier for them as they use their computer. However, there are instances when these hotkeys suddenly stop working. It’s actually one of the most common problems with keyboards. And so to resolve this problem, you can try out some suggestions prepared on this post.

Option 1 – Clean the keyboard keys physically

Your keyboard might not be working properly due to some dirt or other corrosion. First, you need to shut down your computer and then unplug the keyboard if you are using a desktop computer and then prepare it for cleaning. After that, use a small cotton ear cleaning tool to get between the creases and clean them. You can dip it slightly in alcohol to make it more efficient in cleaning dust and dirt. And if you can, you have the option to pull apart the keyboard completely and then wipe away all the corrosion from the inside. Once you’re done, put the keyboard back together and then plug it back into your PC. Now turn your PC on and check if the hotkeys are now working.

Option 2 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem with these function keys. To use it, refer to these steps:
  • The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
  • After opening Settings, look for the Update and Security option and select it.
  • From there, go to the Troubleshoot option located on the left-hand side of the list.
  • Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
  • After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Try connecting the keyboard to a different USB port

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion.

Option 4 – Uninstall previously installed keyboard software

If you have been previously using another keyboard, it might be better if you make sure that the software for the old device has been removed since there are instances when multiple software can cause problems due to similarities in actions.

Option 5 – Update the keyboard driver

You can also update the keyboard driver to fix the problem. There are cases when an outdated or corrupted driver can fix the problem. To do so, follow the steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
  • From there, look for the keyboard driver and click on it.
  • Next, right-click on the keyboard driver and select the Update driver option.
  • After that, click the “Search automatically for updated driver software” option to proceed.

Option 6 – Reinstall the keyboard driver

If updating the keyboard driver didn’t help, then you might want to reinstall it. How? Follow the steps below.
  • Tap the Win + R keys to launch Run.
  • Type in MSC into the box and tap Enter or click OK to open the Device Manager.
  • After that, a list of device drivers will be displayed. Look for keyboard driver, right-click on it and then select “Uninstall device”.
  • After that, unplug the device and restart your PC.
  • Then plug your device back in. Assuming your device is connected to your PC, open the Device Manager again.
  • Next, click on the Action button and click the Scan for hardware changes button. That should fix the problem.
Note: You could also completely uninstall the driver and go directly to the manufacturer’s website and download the latest driver for your hardware and then install it.

Option 7 – Enable Human Interface Device (HID) Service

Another thing to consider is the Human Interface Device Service. If this service is disabled, then no wonder why your hotkeys are not working. Thus, you need to enable this service. Refer to the following steps to do that:
  • Tap the Win + R key to launch the Run dialog box.
  • Then type “services.msc” in the field and hit Enter to open Services.
  • After opening Services, scroll down until you see the Human Interface Device service.
  • Double click on HID and make sure that its Startup Type is set to “Automatic” and then click OK.
  • Restart your PC and check if the hotkeys are now working or not.

Option 8 – Try resetting the keyboard

You might also want to try resetting the keyboard as it can also help in fixing the problem. Setting it back to its default state will surely help.
