How To Fix Error 504

The File Explorer in Windows 10 provides several ways to organize the contents of folders and files in the system. Windows users can utilize some efficient styles to view the contents of the file system as per the user’s requirement. A user may opt to display the file picture in large size thumbnails while the other one could opt to set the icons of folder and files in a small or medium size list. On the other hand, while setting up several styles for the folder and file icons, some Windows 10 users have experienced some unusual issues where there is the Black background showing up behind folder icons. They tried refreshing the File Explorer a couple of times but it didn’t help in fixing the problem and the black squares are still visible on some folder icons. The black squares behind the folder icons might look disturbing though it’s not really a big problem and is merely a graphical glitch that does not cause any damage or whatsoever to the content of the folder and files. The most likely cause of this glitch might have something to do with the corrupted system files or it could also be caused by outdated thumbnail caches. In addition, graphical glitches like this one could also occur if you are using out outdated graphics drivers. To fix this problem, you need to follow the options laid out below.

Option 1 – Try using the Disk Cleanup to remove Thumbnail files

The Disk Cleanup tool is one of the options you can try to fix the black squares behind the folder icons. Through this tool, you can delete all the Thumbnail files on your disk. To use it, refer to these steps:

• Open the Search bar and type “disk cleanup” in the field.
• After opening Disk Cleanup from the search results, then from the drop-down menu select the C: drive to clean up and click OK.
• Wait for the scanning process to complete. Once it’s done, select the files you want to delete.
• Ensure that you select the box labeled “Thumbnails” under the Files to Delete section then click on OK.
• After that, a confirmation box will appear, just click on Delete files to delete the files permanently.
• Restart your PC.

Option 2 – Try resetting the Thumbnail cache

You have the option to manually delete the Thumbnail Cache to resolve the black square background behind the folder icons issue. Follow the steps given below to reset the Thumbnail cache.

• Open the File Explorer.
• Next, navigate to the View tab and select the option with Hidden items to display all the hidden folders and files.
• Next, go to this path: C:Users<username>AppDataLocal
• In the given path, make sure that you put your actual username in the username field. Then look for a file named “IconCache.db”. Right-click on this file and click on Delete.
• After that, go to this path: C:Users<username>AppDataLocalMicrosoftWindowsExplorer
• From there, select all the files and delete them.

Note: If a prompt appears saying, “The files are in use and cannot be deleted”, simply select the “Do this for all current items” option and then click on Try Again. If you get an error message, click on Cancel to close the window and restart your computer.

Option 3 – Try updating or reinstalling the Graphics driver

• Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.
• And then select the outdated driver(s) and right-click on it/them.

Windows 11 release date is closing in, some people have tried it via insider build, some have decided not to. It has come to our attention that there is a little website made by BlueEdge that offers a virtual Windows 11 desktop. Opening the Website will put you right inside Windows 11 desktop, now take note that this is not Windows 11, it is a simulation of Microsoft’s newest OS and therefore many things will not work like File Explorer, etc. One thing you can make sure it is working is UI itself, you can see how you do like the new Taskbar, start menu, widgets, and some other things. You can just pop up on the site and check how you do like the overall new look and feel of Windows 11 UI before installing it or trying it. We are sure that many more options will come in time but even now you can get a feel of the newest OS. Windows 11 BlueEdge site: https://win11.blueedge.me/

Program and features are Control panel section where once accessed contains all programs installed on the operating system. From these windows, any logged-in user can modify applications, uninstall them, etc. If for whatever reason you want to limit this access to users and remove this group from the control panel please do keep reading as we show you how you can achieve this desired result using two methods: via policy editor or registry editor. Feel free to use any provided method as both works (except on Windows 10 Home edition) and achieve the same thing, it all comes down to preferred preference on how you wish to do things.

Local group policy editor method

This method is more straightforward and easier perhaps than its counterpart but it has one significant drawback, it will not work on Windows 10 Home edition which does not have in itself a policy editor included. If you are using Windows 10 Home edition then feel free to skip this method and do it via registry editor. That being said let's start:

• Press ⊞ WINDOWS + R to open the run dialog
• Inside run dialog type in gpedit.msc followed by ENTER to open Group policy editor
• Go to User Configuration\ Administrative Templates\ Control Panel\ Programs\
• Double-click on the setting named Hide Programs and Features page
• Change the toggle option from Not Configured to Enabled
• Click on the Apply button and then the Ok button to save the changes
• at this point, everything is supposed to be applied and your changes should take effect immediately. However, it has come to our attention that sometimes this is not the case. If you are one of these users which for whatever reason have not experienced applying to set momentarily do not despair and follow this quick guide on how to refresh settings and apply them right away.
• Press ⊞ WINDOWS + X to open the hidden menu
• Click on command prompt (admin)
• In command prompt type in gpupdate /force and press ENTER in order to force update and set setting right away

Registry editor method

The registry editor method is a more complex one but it will be your only way of doing it if as mentioned you are running Windows 10 Home edition. As always it is highly recommended to make a backup of the Windows registry before tempering with it.

• Press ⊞ WINDOWS + R to open the run dialog
• Inside run dialog type in regedit and press ENTER to open the registry editor
• If you would like to make a backup of the Windows registry go to File > Export and save the backup on a secure location naming it as you wish
• Locate the following key inside the registry editor HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Programs
• Right-click on the right pane of the Programs key and choose the New > DWORD (32-bit) Value option
• Name the value as NoProgramsAndFeatures
• Double-click on the NoProgramsAndFeatures value to open it
• Change the value data to 1
• Save the changes
• Reboot the computer in order for changes to take effect.

note: you can always change values back in order to show again panel by changing the value to 0 in registry editor or choosing Not Configured or Disabled in the local group policy editor

How To Install Safebytes Anti-Malware On An Infected Computer system

Practically all malware is bad, but certain kinds of malware do more damage to your computer or laptop than others. Some malware sits in between your PC and your internet connection and blocks some or all sites that you would like to check out. It would also prevent you from the installation of anything on your PC, especially antivirus software. If you are reading this article right now, you’ve perhaps realized that a malware infection is a reason for your blocked internet traffic. So what to do if you want to install an anti-virus program like Safebytes? There are a few actions you can take to get around this issue.

Use Safe Mode to resolve the issue

In Safe Mode, you can modify Windows settings, un-install or install some software, and eradicate hard-to-delete malware.

In order to get into Safe Mode or Safe Mode with Networking, press F8 while the system is booting up or run MSConfig and locate the “Safe Boot” options in the “Boot” tab. Once you restart the PC into Safe Mode with Networking, you could download, install, and update anti-malware software from there. Now, you are able to run the anti-virus scan to remove viruses and malware without interference from another malicious application.

Switch to a different internet browser

Some malware mainly targets certain web browsers. If this is your case, utilize another browser as it could circumvent the malware. If you suspect that your Internet Explorer has been hijacked by a trojan or otherwise compromised by cybercriminals, the best course of action would be to switch over to a different internet browser like Google Chrome, Mozilla Firefox, or Apple Safari to download your chosen security program – Safebytes Anti-Malware.

Make a bootable USB anti-virus drive

As you know, any software needs sufficient CPU power when it downloads, updates and installs so if you encounter an error code 0x80200070 when you tried to install or update the Microsoft Edge browser on your Windows 10 computer, then read on as this post will guide you on how to fix it. This kind of error occurs when the Edge browser installation does not get enough CPU power to update or install and the only way to fix it is to kill programs that are consuming a lot of PC resources as well as stop or remove any unnecessary programs that are running in the background. This kind of error can also be encountered in the new Microsoft Edge Chromium. For more details, follow each one of the options provided below.

Option 1 – Try to kill applications that consume high resources

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Go to the Performance tab and sort by CPU usage.
• Next, close a few additional programs that are consuming maximum CPU power.
• After that, try to update or install Microsoft Edge again and check if the error is fixed. If not, try to restart your computer and then start the installation or update again.

Option 2 – Try to remove or stop unnecessary programs and services

If the applications or processes that are consuming a lot of CPU resources reappear even after you kill them or end their processes, then you can try the following suggestions to remove or stop these unnecessary programs and processes.

• The first thing you can do is to stop the Service. If the program happens to be a service, then you have the option to disable the Windows Service. All you have to do is open the Services Manager and stop the service. How? Refer to these steps:
  • Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and tap Enter to open the Services Manager.

• After that, identify which service is consuming a lot of power and then stop it temporarily.
• The next thing you can do is to uninstall the problematic program. If the one that consumes a lot of resources is not a service but a program, then you can try to uninstall the program for the meantime until you’ve updated or installed the Edge browser. Once you’ve uninstalled the program, try to update or install Edge again.
• You can also try booting your computer into Safe Mode and then update or install Microsoft Edge. This will make sure that all the unnecessary programs and services won’t consume a lot of CPU resources as well as memory.

A lot of users rely on keyboard shortcuts to carry out tasks on their PCs. One of the most common keyboard shortcuts used is the Ctrl + Shift + Esc which opens the Task Manager. As you can see, the Shift key is not just used to capitalize a text as it can also be used for other functions and plays an essential role in operating a computer. However, if you suddenly find it not working, read on as this post will help you fix the problem. If your Shift key is not working, there are several potential fixes you can check out to fix it. These are the different ways to get rid of the Shift key not working issue on Windows 10:

1. Physically clean the key and keyboard
2. Disable Sticky Keys.
3. Update, Reinstall, or Rollback Keyboard driver.
4. Test the keyboard on another system.
5. Check your connections
6. Run the Hardware troubleshooter
7. Troubleshoot in Clean Boot State.

Option 1 – Clean the keyboard keys physically

Your keyboard might not be working properly due to some dirt or other corrosion. Thus, you need to clean your keyboard, especially the Shift key. 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 Shift key is now working.

Option 2 – Try to disable the Sticky keys

Another thing you can try is to disable the Stick keys. How? Refer to these steps:

• Tap the Win + I keys to open the Settings app.
• After that, navigate to the Ease of Access section, and here, select Keyboard.
• Next, make sure that the option for Press one key at a time under the Sticky Keys is toggled off.

Option 3 – Reinstall, update or rollback your keyboard driver

Once you’ve determined that the problem is in the software part of the keyboard, it is now time to try to reinstall, update or roll back your keyboard drivers. To reinstall the driver for your keyboard, refer to these steps:

• From the WinX Menu, open the Device Manager.
• In the Device Manager, you should find your laptop’s keyboard under the “Keyboards” option. Right-click on it and select the “Uninstall” option.

Note: If you’re not quite certain about your laptop’s keyboard, you can uninstall all the keyboards if there’s more than one.

• After that, restart your PC and see if the keyboard driver is installing automatically. If not, open the Device Manager again and right-click on Keyboards, and select the option “Scan for hardware changes” to install it.

Once the keyboard driver is installed again, check if your keyboard is now working properly or not.

Option 4 – Try connecting the keyboard to a different USB port or another computer

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. In addition, you can also try connecting the keyboard to a different computer and see if the Shift key works there or not.

Option 5 – Try to check your connections

You can also try checking if the connection mode you are using for your keyboard is functioning properly. For instance, if you are using a Surface 2-in-device, you can clean the connection pins and see if it resolves the problem.

Option 6 – Run the Hardware and Devices Troubleshooters

• 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 7 – Put your PC in a Clean Boot State

You might also want to put your computer in a Clean Boot State to fix the problem with the Shift key. It could be that there is a third-party program that’s preventing the Shift key from functioning. To isolate this possibility, you need to put your computer in a Clean Boot State.

• 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 connect the external devices and check if the error is now gone.

Usually when online service is not working or when something goes wrong online it is DNS, well that is what most of the time is the case. And yes, DNS or Domain Name Server seems to be an issue with Facebook being completely down along with Instagram and wassap. The true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP. Cloudflare VP Dane Knecht was the first to report the underlying BGP problem. This meant, as Kevin Beaumont, former Microsoft's Head of Security Operations Centre, tweeted, "By not having BGP announcements for your DNS name servers, DNS falls apart = nobody can find you on the internet. Same with WhatsApp btw. Facebook has basically de-platformed themselves from their own platform." Many people are very annoyed by this and with the fact that they cannot use their social media platforms but it seems that Facebook employees are in even bigger annoyance as it was reported that Facebook employees can't enter their buildings because their "smart" badges and doors were also disabled by this network failure. If true, Facebook's people literally can't enter the building to fix things. Reddit user u/ramenporn, who claimed to be a Facebook employee working on bringing the social network back from the dead, reported, before he deleted his account and his messages: "DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC). There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures." Ramenporn also stated that it wasn't an attack, but a mistaken configuration change made via a web interface. Both BGP and DNS are down, the "connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally." Technicians on site don't know how to do that and senior network administrators aren't on site. It seems that it will all be down for a couple of more hours before the issue is resolved.
