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.

As you know, games with good graphics and fast play are definitely resource-intensive and can consume a lot of storage space on your computer. Because of that, they have to be compressed before it gets downloaded to your computer and then unpacked to the hard drive before it gets installed. However, if an error occurs in your computer’s RAM during the installation process or if your hard disk does not have enough memory to handle the process, then you might encounter the isDone.dll error which states:

“An error occurred when unpacking, Unarc.dll returned error code -1, ERROR: archive data corrupted (decompression fails).”

If you encounter the isDone.dll error message on your Windows 10 computer, then read on as this post will show you how you can fix it. This error has something to do with the incomplete installation of PC games or files of larger size. The ISDone.dll error appears due to faulty Unarc.dll file residing in the System32 folder on 32-bit operating systems and the SysWOW64 folder on 64-bit systems. So, if you see this error message, then, it means your computer was not able to read installation archive files.

What is Unarc.dll file?

Unarc.dll is a dynamic link library for Windows. Some applications or games require this file to function properly. So, if it goes missing or, an error occurs when you start a game or an application, you may get various kinds of errors. ISDone.dll error while playing games on PC

Option 1 – Try to reinstall the game

The isDone.dll error could also be caused by the installation of an unknown application. Or it could also be caused by an outdated or corrupted application. In other words, if the game you are trying to install is broken or corrupted, then it’s no wonder why you’re getting the isDone.dll error. To fix this, make sure that you download the latest updated version of the game and then try to install it again and see if the problem is resolved or not.

Option 2 – Try to re-register the .dll file using the Regsvr32 tool

• The first thing you have to do is to locate the DLL file named dll on your computer and rename it to Unarc-bak.dll.
• Next, copy the Unarc.dll file from another well-functioning computer and save it on your desktop.
• After that, move the DLL file you just copied to the System32 folder if you are using a 32-bit operating system, or the SysWOW64 folder if you are using a 64-bit operating system.
• Now you have to register the new DLL file and you can do that using Windows PowerShell.
• Open Windows PowerShell and then execute this command if you have placed the DLL file in the System32 folder: regsvr32 %systemroot%System32unarc.dll
• On the other hand, if you have placed the DLL file in the SysWOW64 folder, then execute this command: regsvr32 %systemroot%SysWOW64unarc.dll
• Once you’re done, a message will be displayed saying that the DLL file was registered.
• Restart your computer and check if the problem is now fixed.

Option 3 – Troubleshoot the isDone.dll error in a Clean Boot State

You can also troubleshoot the isDone.dll error in a Clean Boot state. It could be that there are some third-party applications in your computer that're preventing the application from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem.

To fix this 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.

As you know, the functioning of the Windows Sandbox feature is supported by various components in the background of the Windows operating system. And the only way for you to enable the Windows Sandbox feature in your computer is through the Turn Windows features on or off utility. This feature will work directly on the basis of Virtualization which is also supported by Hyper-V. However, there are some reports claiming that some computers have the Windows 10 Sandbox item greyed out in the Turn Windows features on or off utility. Thus, in this post, you will be guided on what you can do to resolve such a problem in your Windows 10 computer. In this kind of problem, you should know that this has something to do with the Second Level Address Translation which is one of the important pillars of how the Windows 10 Sandbox feature functions. Thus, if the Second Level Address Translation or SLAT feature in Windows Sandbox is not supported by the CPU of your computer, there is no way for you to use Windows Sandbox on your computer. On the other hand, if SLAT is supported, then there is definitely something you can do to resolve the greyed-out Sandbox item in Windows 10.

To get started, follow the steps provided below.

Step 1: First, you have to boot into the BIOS of your PC. Step 2: After that, make sure that the following options are set to their respective configurations:

• Hyper-V – Enabled
• VM Monitor Mode – Yes
• Virtualization – Enabled
• Second Level Address Translation (VT-d or RVI) – Enabled
• Data Execution Prevention – Enabled

Step 3: Once you’re done, save the configuration and then restart your Windows 10 computer as usual. Step 4: Once your computer has restarted, you should see the same option in the Turn Windows features on or off utility and it should no longer be greyed out. Then you can now enable the feature and follow the onscreen instructions need to use the feature as best as you can.

One of the selling points of Windows 11 was the ability to run Android apps natively in it without the need for any third-party software. It is not a big surprise that even after its release Microsoft is evolving and expanding Windows 11 and its features.

Microsoft is now rolling out an update for the Windows Subsystem for Android on the Dev Channel of the Windows Insiders program. The new version upgrades the core operating system from Android 11 to Android 12.1 (also known as Android 12L), which means the new system and app features in Android 12 and 12.1 are now available on Windows for the first time. However, not the new features in those updates apply to the modified version that runs on top of Windows. For example, one of the main improvements in 12.1 was a dual-pane notification panel for larger screens, but Android app notifications on Windows just show up in the Windows notification panel.

The upgrade also improves how Android apps integrate into Windows. The Windows taskbar will now show which Android apps are currently using the microphone, location, and other system services — similar to many native Windows applications. Toasts messages (the small popups that some apps use for temporary messages) are now displayed as Windows notifications, and the titlebar on Android apps will use the current activity name for the title.

Full changelog

• Windows Subsystem for Android updated to Android 12.1
• Advanced networking on by default for newer x64 Windows builds
• Updated Windows Subsystem for Android Settings app: redesigned UX and diagnostics data viewer added
• Simpleperf CPU profiler recording now works with Windows Subsystem for Android
• Windows taskbar now shows which Android apps are using microphone and location
• Improvements to Android app notifications appearing as Windows notifications
• Reduced flicker when apps are restored from minimized state
• Apps are not restarted when devices come out of connected standby on recent Windows builds
• New video hardware decoding (VP8 and VP9)
• Fixes for on-screen keyboard in apps
• Fixes for full-screen Android apps and auto-hidden Windows taskbar
• Windows Subsystem for Android updated with Chromium WebView 100
• Added support for Android NetworkLocationProvider in addition to GpsLocationProvider
• Improved general stability, performance, and reliability

The new update is limited to Windows Insiders for now, but once Microsoft fixes all the bugs, it should start rolling out to everyone on Windows 11 that has the Android Subsystem enabled.

On September 18th, 2017, Cisco’s Talos announced that CCleaner, a popular utility with billions of worldwide users, had been compromised by hackers, and was used to unwittingly distribute hidden malware in its installer. Later in the day, Piriform, the publisher of CCleaner, confirmed the problem.

Undetected by all but 1 major antivirus including CCleaner’s own parent company, this occurred for over a month and impacted over 2.7 million users. Users of CCleaner v5.33.6162 and CCleaner Cloud v1.07.3191 for 32-bit Windows are affected. These downloads were live on CCleaner’s official site from August 15th to September 12th, 2017. Anyone who downloaded the program during this time could be affected. The company claims that while the hackers set up the backdoor and many users were impacted, that the perpetrators have been arrested and that the malware never successfully performed its full task and compromised user’s PCs or sent out their data; in the wake of recent security breaches such as Equifax, users are understandably worried. Given the severity of the threat of hacking and data theft, users should take action immediately if they have CCleaner.

Technical Details of CCleaner Malware Injection

First reported by Talos, the malware, which was hidden in the CCleaner installer without the publisher noticing (despite them being owned by Avast, a massive Anti-virus company), modified a core program DLL file to evade detection, and creates several registry keys. Not only were these files not flagged by any major Anti-Virus, but they were also even digitally signed by Piriform via their Symantec certificate, meaning your PC and security program would likely whitelist and trust the malicious installer. The malware gathers personal information on a user’s PC, including IP address and running programs, and sends it to a remote server. In our testing, the program sent data to IP 216.126.225.148.

Restore Your PC (If Possible)

As of the publication of this article, there have been no assurances given that updating or even uninstalling CCleaner will remove the malware is installed. The only action thus far has been shutting down the remote server where user data was being sent has been shut down by authorities. For this reason, it is best to remove the underlying malware separately, as its presence represents a serious security threat. Unfortunately, as this could have been installed as far back as August 15th, 2017, your System Restore points may not go back that far, or even if they do, restoring to such an outdated point may cause unintended problems with other programs you use and potentially lost files and data. Manually backing up files and doing a full format or clean Windows installation would likely be successful in fully removing the malware, but is extremely time-consuming and can be difficult for many PC users. Unfortunately, this makes a PC Restore or format an unattainable option for many.

Update CCleaner to the Latest Version

While CCleaner has told users to update to the latest version of the program. Prior to doing so, we recommend fully uninstall CCleaner, ensuring you check its program files folders and registry keys, manually deleting any remnants, and then re-downloading the latest version from the official site and reinstalling clean.
