The occurrence of this error regardless of what the cause is may cause a lot of inconvenience to you. And if not fixed on the time it can lead to system failure too. To repair the error 501, identifying the cause for the error really helps. By identifying the cause, you can easily select the most suitable solution to fix it.

Let us walk you through the solutions to fix error 501 timely:

Cause: Third-party conflicts or due to an incorrect HTTP 1.1 setting

Solution: If the above cause is the reason for error 501, this means the Local Policy Rights Settings have been altered. And because of that, Windows is not running your desired program. To solve this error simply log on to Windows as an administrator. Then run local computer policy snap-in. Open it and click on the computer configuration. Here you will see the Windows settings option. Click on it and then open security settings, local policies, and click on properties. Now in the add users section select the user which you want to add to the policy and save by pressing OK. After you’ve made changes, now try using internet explorer again. If this is the cause for the error pop, the error will not occur. If it still occurs then this means there is some other underlying cause for the error. Read on to find out.

Cause: Improper Program Installation

Solution: Error 501 may also occur due to improper program installation. The best way to resolve it is to uninstall recently installed programs.

Cause: Changes in the “LocalAccountTokenFilterPolicy” registry key

Solution: Sometimes during installation registry keys also get damaged or changed. If changes in the LocalAccountTokenFilterPolicy” registry key is the issue, then you need to alter the registry key ‘LocalAccountTokenFilterPolicy settings and its value. This key inside the registry database allows Windows to control the various access options that you have.

Sometimes, some applications after they are installed will put their shortcut in the context menu (right-click on desktop) for easy access, most of the time these are some system tied applications like AMD and Nvidia control panels or archives like WinRAR or 7ZIP but it can happen even for some usual application to do this.

There are some applications that you use frequently and they could be worth putting in the context menu, if you want to avoid clutter on the desktop or in the taskbar this is the third place that you should consider placing shortcuts.

Doing this will require some playing and tweaking in the Windows registry editor so be careful when editing the registry since bad entries can lead to system crash or instability. Follow step-by-step instructions.

Adding apps to the context menu in the registry

Creating entry

Open the registry editor by searching Regedit and pressing enter than inside of the registry editor search for the next key:

HKEY_CLASSES_ROOT\Directory\Background\shell

Select shell and right-click on it, hover over New and in the submenu click on Key. In the next step, you need to name a key, this name will be the thing that will be shown in the context menu when you right-click on a desktop so type in the name that you would like or the name of the application that you wish to add to the menu.

If you wish you can even add a keyboard shortcut to launch this specific application. To do this select entry that you have created and edit the default value, inside the edit string in the Value data field type first & and after that key that you would like as a shortcut. Now after right click if you hit your shortcut key app will be launched right away.

Adding command

The next task is to create a command key that will actually hold the command to launch the application. Right-click on the entry that you have created, hover over New, and click on Key.

Next, you’ll need to create the command key that will actually hold the command used to launch the application. Right-click on the new Notepad key, and then choose New \ Key from the menu. Name this key 'command', all in lower case and without hyphens.

Now in order to finish setting the launcher, you need the full path of the file that you would like to run. Locate your file in file explorer or in another tool and copy its path by SHIFT + right-clicking on the file itself and choosing copy as path option.

Now click on the command key and double click on the default key on right to edit it, inside the field value data paste your path to executable. close and save the registry and you are done.

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.

Auxiliary image items

Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.

There are times when you suddenly encounter a Blue Screen error like DRIVER_POWER_STATE_FAILURE error when resuming from Sleep or right after you shut down or restart as well as switch from Hibernate mode. This kind of Blue Screen error is due to some issue with the driver state. Moreover, the bug check “0x0000009F” in the error also indicates that a driver is in an inconsistent or invalid power state. The DRIVER POWER STATE FAILURE Blue Screen error usually occurs during events that involve power state transitions like shutting down, moving in or out of standby mode, or hibernate mode. To resolve this error, you can check out the suggestions given below.

Option 1 – Update the Device drivers

The device driver installed in your computer might be incompatible with your operating system which is the reason why the DRIVER POWER STATE FAILURE Blue Screen error occurs. To fix that, you have to update your device drivers.

• Reboot your computer into Safe Mode with networking support.
• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “msc” in the field and hit Enter or click OK to open the Device Manager.
• After opening the Device Manager, update all the outdated Device drivers on your computer.
• Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
• Now restart your PC and check if the BSOD error is fixed or not.

Option 2 – Uninstall any faulty device drivers

• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “msc” in the field and hit Enter or click OK to open the Device Manager.
• From there, look for any device driver which has a yellow exclamation mark which indicates that something is wrong with them.
• And then right-click on each one of them and click on Uninstall.
• Once you’re done uninstalling the faulty drivers, restart your computer and allow your computer to reinstall the drivers you just uninstalled.

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 like rtwlane.sys Blue Screen error. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 4 – Try to remove external hardware

If there is any external hardware plugged into your computer especially the new ones, you can try removing it and then check if the Blue Screen error persists. If the problem gets solved, you might want to update the driver of that particular hardware. On the other hand, if you’re still getting the error, then proceed to the next given options below.

Option 5 – Try resetting Windows 10

To fix this BSOD error, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files.

Option 6 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the DRIVER POWER STATE FAILURE Blue Screen error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to 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.

Scammers have decided to target Windows’s 10 App installer process in order to infect your computer and steal your data. As in most usual online scams, everything starts with a strange email containing threats and other poorly written and composed speech. At the end of the given email, there would be a link claiming that you, of course, need to read it and follow instructions about the threat, if you click the link it will open a web page where you will have an innocent-looking PDF file with more information about the threat itself. If you click on a seemingly innocent PDF file it will summon Windows 10's AppInstaller.exe tool, kickstarting a download-and-run process that'll put you in a bad place very quickly. From there, you'll have to deal with the dangers of malware BazarBackdoor, including data and credential theft. This kind of scam is nothing new but the interesting thing here is that it uses App installer and by clicking on a link you are opening and giving permission for a malicious crook to use it. So, stay safe and do not click on any links from unknown emails no matter what.

If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites. If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:

“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”

And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.

Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs

Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.

Option 2 – Try to disable security.enterprise_roots.enabled

The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.

• Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
• After that, if an info message appears, confirm it.
• Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
• Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.

Access denied error code 16 is tied to websites, it is an error which you will encounter when trying to visit some specific website or if you are unlucky on all of the websites. Lucky for us this error is fixable and in order for us to do this, follow this guide for possible solutions.

A lot of users complain about low storage space each time a Windows Feature update is released as well as to complain about not being able to download the updates, slow update experience, and many other complaints. The main issue is that many users do not have enough storage space available on their PCs. And now to make sure that none of the updates gets stuck because of low storage space, Microsoft presented the Reserved Storage feature which comes preinstalled with v1903 or those where v1903 was clean installed. This guide will be showing you how you can enable or disable the Reserved Storage in your Windows 10 computer. As you know, the Windows Update process should have enough space so that it can download, extract and apply the update on the computer. Usually, the size of the Reserved Storage is around 7GB which gives enough space for the update, temporary files, system caches, apps, and many more. And according to Microsoft, the size of the Reserved Storage space will vary from time to time and will depend on how you use your computer.

Explanation

The Reserved Storage space feature is enabled by default on devices that come preinstalled with the May 2019 update or after performing a clean installation of the Windows 10 OS. To check if your computer has this feature, you need to go to Settings > System > Storage and from there click on the “Show more categories” link and then click on the “System & reserved” option. However, if you can’t find the Reserved Storage from the list, then it’s probably because your computer has limited space on the hard disk or it is not a fresh or new install. On the other hand, if you have this feature but have no use for it and want to disable it instead, then read on as this post will also show you how it’s done.

Solution

Keep in mind that when you disable the Reserved Storage feature, chances are, you might be unable to enable it back so you need to make sure that it’s really what you want to do before you disable it permanently. So if you really want to disable Reserved Storage, you can do so using the Registry Editor. Before you proceed, you have to create a System Restore point first and then carry out the following steps.

• Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionReserveManager
• From there, double click on the DWORD named “ShippedWithReserves” and set its value to “1”.
• Once you’re done, restart your computer and see if the Reserved Storage feature is now gone.

On the other hand, if you want to reduce the Reserved Storage space, there are two ways you can do that. First, you can go to Settings > Apps > Apps & features > Manage optional features and from there, uninstall the optional features that you do not use. The second one is you have to go to Settings > Time & Language > Language and then uninstall the languages and their add-on which you don’t use. Note: The Reserved Storage feature is also used by system processes and apps to create temporary files and once the Reserved Storage space fills up, Windows 10 will delete them automatically. It is undeniable a useful feature so disabling it is not recommended but if you are running on low storage space and don’t have much choice, then you may disable it at your own risk.
