There are situations where you need a specific Windows system file from the install.wim image present in a Windows 10/11 setup disk or ISO. In the case of missing system files, the DISM & SFC procedure will automatically restore them. Alternatively, you can restore missing Windows system files (of any version) from the WinBindex.Read more
You may be unable to download new apps or update existing apps using the Microsoft Store due to error 0x800706D9 — Something unexpected happened. Error code 0x800706D9 translates to “There are no more endpoints available from the endpoint mapper”, which doesn’t make much sense for the end-user.
Also, the same error is shown when you install or update apps using PowerShell.
The error message is:
Add-AppxPackage: Deployment failed with HRESULT: 0x80073CF6, Package could not be registered. error 0x800706D9: While processing the request, the system failed to register the windows.firewall extension due to the following error: There are no more endpoints available from the endpoint mapper.
This post tells you how to fix Microsoft Store 0x800706D9 in Windows 10 and 11.Read more
Since July last week, Windows Defender started issuing Win32/HostsFileHijack “potentially unwanted behavior” alerts if you had blocked Microsoft’s Telemetry servers using the HOSTS file.
Out of the SettingsModifier:Win32/HostsFileHijack cases reported online, the earliest one was reported at the Microsoft Answers forums where the user stated:
I’m getting a serious “potentially unwanted” message. I have the current Windows 10 2004 (1904.388) and only Defender as permanent protection.
How is that to evaluate, since nothing has changed at my hosts, I know that. Or is this a false positive message? A second check with AdwCleaner or Malwarebytes or SUPERAntiSpyware shows no infection.
After inspecting the HOSTS file from that system, it was observed that the user had added Microsoft Telemetry servers to the HOSTS file and routed it to 0.0.0.0 (known as “null-routing”) to block those addresses. Here is the list of telemetry addresses null-routed by that user.Read more
When you run a program on a computer running Windows 8.1 or earlier, you may see an error denoting that the module api-ms-win-crt-heap-l1-1-0.dll or api-ms-win-crt-runtime-l1-1-0.dll is missing. Here’s the full error message verbatim:
For example, these errors may occur when playing online games or while running programs that were compiled using Microsoft Visual Studio 2015 & Windows 10 SDK — e.g., Office Word, Excel, Access, Skype, QGIS, Apple iTunes, or Adobe products.
These DLL missing errors usually indicate that the VC++ runtime libraries are missing. A runtime library is a collection of files (usually .dll files) used by some programs at run-time to provide one or more native program functions or services.
Uninstalling and reinstalling the respective program can help in cases where the software vendor has packaged the runtime library within the installer.
Many users have attempted to download and install the Visual C++ Redistributable for Visual Studio 2015. However, this may not resolve the issue. This article tells you how to fix the above errors easily using an update released by Microsoft.Read more
A long time back, most of the software used to ship with .hlp (WinHelp help format) help files. Since Windows Vista, the legacy .hlp format has been deprecated. To view 32-bit Help files with the .hlp file extension in Windows Vista (and higher — through Windows 8.1), you will need to download and install WinHlp32.exe (KB917607 package) from the Microsoft Download Center.
However, this update isn’t available for Windows 10/11. Installing one of the KB917607 installers on Windows 10 or 11 would cause the following error:
Windows Update Standalone Installer The update is not applicable to your computer.
This article tells you how to restore the missing WinHelp (.hlp) viewer on Windows 10 or 11.

If a Windows system file is missing, the first thing that comes to our mind is the System File Checker (Sfc.exe). The sfc.exe /scannow command-line restores missing or corrupted system files by fetching a good copy from the WinSxS folder. If that fails, you usually run the DISM .. RestoreHealth command-line to fix the WinSxS repository. In some cases, DISM requires a slipstreamed Windows setup disk from which the install.wim file is used.
Here is another way to download any version of a Windows system file (.exe, .dll, or .sys) directly from Microsoft’s server.Read more
Twitter videos are .m3u8 playlist files that link to multiple .ts (Transport Stream) video stream files. The Twitter user interface doesn’t provide an option to download the video embedded in a tweet or Direct Message (DM).
There are 3rd party Twitter video downloader websites such as savetweetvid.com, twdown.net etc., that can download Tweet videos, but they can’t download your Twitter Direct Message (DM) videos.
This article explains how to download a video from Twitter DM using your web browser (instead of the Twitter app), browser extension, or a third-party tool such as VLC Player or Youtube-DL.
Windows Media Audio (WMA) is a proprietary technology developed by Microsoft that forms part of the Windows Media framework. WMA produces better sound at low bitrates compared to MP3. It leads to smaller file sizes. Since the WMA format is proprietary, we have more devices that use the MP3 format compared to WMA.
If your device (e.g., DVD player) doesn’t support WMA file format, then you’ll have to convert the WMA files into MP3, as most, if not all devices support MP3. Converting WMA files to MP3 is also a good idea if you want to play them across different platforms (e.g., macOS, iOS, Android, ChromeOS, or Linux). For instance, Chromebooks don’t have native support for WMA files. You’ll need to install VLC Player for Chrome OS or convert the WMA files to one of the formats (.mp3, .m4a, .ogg, .wav) to be able to play the music on your Chromebook.
Windows Media Player is the native media player (in Windows Operating Systems) which supports WMA file format. But Windows Media Player has no audio format conversion capability. However, WMP can rip CD/DVD audio into WMA, WAV, or MP3 file format, though.
The error 0xc1900223 may appear when you attempt to update your Windows 10 installation, especially when installing a feature update like v1903 or v1909. There is no actionable advice from Microsoft, regarding this error.
However, the error continues to occur even when attempting to install the update every time.
The SetupDiag utility (download) would log this error:
Error: SetupDiag reports abrupt down-level failure. Last Operation: Finalize Error: 0xC1900223 - 0x20009 LogEntry: Error MOUPG CSetupManager :: ExecutePreDownloadMode (8491): Result = 0xC1900223
The usual Windows Update troubleshooting methods may not fix this error. This post tells you how to prevent the error 0xc1900223 in Windows 10.Read more
Windows 10 updates, especially the feature updates, consume enormous disk space as Windows stores the older copies in case you want to roll back to the previous version. Hard disk drives have become cheaper and affordable nowadays. A 1 TB SATA HDD costs less than $50. But, if you’re using an old, low-capacity hard drive from an old computer and want to free up disk space, this article tells you how to do that.
After installing a feature update, Windows 10 automatically cleans up the previous Windows installation files (Windows.old) after ten days. However, there are some other ways with which you can free up disk space in Windows. Let’s see some of the options.Read more
