QTTabBar is a Shell-Extension to add Tab functionality to Windows Explorer - folder window.
Besides, QTTabBar provides various features that certainly help you deal with files and folders.

What can it do?

Most of the functionalities are activated when you enable the toolbars offered by QTTabBar in a folder window.

Tab Bar realizes ... the tabbed browsing of folders. Command Bars offer various command buttons including ones added by Plug-Ins. Extra Views show extra folder view in a folder window.

This privilege escalation vulnerability has lurked within Windows for 20 years.

Microsoft is announcing a new application named the Windows Terminal. It will include multiple tabs along with themes and other customization features. The Windows Terminal uses GPU-based text rendering and even supports emoji. It includes tabs so you can open Cmd, PowerShell, and WSL consoles in a single window.

This application won’t immediately replace the classic Windows Console environment. The source code is already available on GitHub.

Beyond the visual changes, Microsoft also announced “Windows Subsystem for Linux 2.” It will reportedly offer up to twice the performance of the current version of WSL for filesystem-heavy operations. Windows 10 will include a Linux kernel to make this possible.

I ran the following commands from the Windows command prompt to reset my password. Anything after the # is a comment:

ubuntu config --default-user root
ubuntu.exe # (to run WSL in the current Windows command prompt)
whoami # (to see who I'm currently logged in as)
tail -3 /etc/passwd # (to see the last three users added to the Ubuntu system)
passwd user01 # (to change the password for user01)
exit # (to exit WSL)
ubuntu config --default-user user01 # (to set the default user for the WSL terminal)

Substitute debian.exe as appropriate

Microsoft has released an Insider Preview Build that includes the new Windows Sandbox feature. If you’re on the Fast track, you can download and start using it today.

Note: Windows Sandbox is not available on Windows 10 Home. It’s only available on Professional, Enterprise, and Education editions of Windows 10.

#What is Sandbox?

In short, Windows Sandbox is half app, half virtual machine. It lets you quickly spin up a virtual clean OS imaged from your system’s current state so that you can test programs or files in a secure environment that’s isolated from your main system. When you close the sandbox, it destroys that state. Nothing can get from the sandbox to your main installation of Windows, and nothing remains after closing it.

I upgraded my Windows hard drive, and now have a space problem.

I inserted a new 240GB SSD, used CloneZilla to clone my old 120GB Windows C: drive SSD to this new one, switched the SATA cables, and turned on the computer.

Everything works great with the new SSD being the C drive, but it shows the old hard drive's space for some reason in Windows Explorer, while in Disk Management it shows the correct space. I restarted the computer and it was the same thing. Does anyone know what's going on?

1. Use Disk Manager to shrink the volume by 2MB (should happen very quickly - shrinking by large amounts will take a long time).

2. Windows should then discover and display the extra space.

3. Extend the volume as desired.

Four years after its release, we’re all still using Windows 10. But that’s not really true: The version of Windows 10 we’re using today has seen four years of improvements. It’s packed with shiny new features and clever under-the-hood optimizations. //

Despite the version number, the Windows 10 operating system we’re all using today is practically a new version of Windows. If Microsoft kept the naming scheme from Windows 8.1, we’d be on Windows 10.7 by now.

Tamper Protection blocks attempts to modify Windows Defender Antivirus settings through the registry. To help ensure that Tamper Protection doesn’t interfere with third-party security products or enterprise installation scripts that modify these settings, go to Windows Security and update security intelligence to version 1.287.60.0 or later. Once you’ve made this update, Tamper Protection will continue to protect your registry settings and will log attempts to modify them without returning errors.
If the Tamper Protection setting is On, you won't be able to turn off the Windows Defender Antivirus service by using the DisableAntiSpyware group policy key.

How to Confirm Exploit Protection is Enabled

This feature is automatically enabled for all Windows 10 PCs. However, it can also be switched to “Audit mode”, allowing system administrators to monitor a log of what Exploit Protection would have done to confirm it won’t cause any problems before enabling it on critical PCs.

To confirm that this feature is enabled, you can open the Windows Defender Security Center. Open your Start menu, search for Windows Defender, and click the Windows Defender Security Center shortcut.

Some SSDs advertise support for “hardware encryption.” If you enable BitLocker on Windows, Microsoft trusts your SSD and doesn’t do anything. But researchers have found that many SSDs are doing a terrible job, which means BitLocker isn’t providing secure encryption.

Update: Microsoft has issued a security advisory about this problem. It includes a command you can use to check whether you’re using hardware or software encryption. //

navigate to the following folder
%userprofile%\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets

In the folder, you’re going to see a whole bunch of files with long, meaningless file names and no extensions. Some of these are the image files you’re looking for; many are not. Just create a new folder anywhere you like, select all files in the Assets folder (Ctrl+A is the quickest way), and then copy them to the new folder.

When you do this, Windows will warn you that some of the files may be harmful to your computer. This is just because you’re moving them from a system folder and Windows doesn’t recognize the file types (since no extensions are assigned).

In the File Explorer window, with your new folder showing, click File > Open Command Prompt, and then choose “Open command prompt as administrator” to open the Command Prompt at your current location.

At the Command Prompt, type (or copy and paste) the following command and hit Enter:

To install and start using WSL 2 complete the following steps:

• Enable the 'Virtual Machine Platform' optional component
• Set a distro to be backed by WSL 2 using the command line
• Verify what versions of WSL your distros are using

Please note that you'll need to be running Windows 10 build 18917 or higher to use WSL 2, and that you will need to have WSL already installed (you can find instructions to do so here).

In Windows 10, Microsoft ditched the good old calculator app and replaced it with a new Modern app, which we wrote about recently here: Run Calculator in Windows 10 directly. Many people are not happy with this change because the old Calc.exe loaded faster, and was more usable for mouse/keyboard users. If you would like to get the classic Calculator app back in Windows 10, it is possible. In this article, we will take a look at the Old Calculator for Windows 10 program which will allow you to get Calculator from Windows 8 and Windows 7 in Windows 10.

A tool to limit the bandwidth (upload/download) of devices connected to your network without physical or administrative access. evillimiter employs ARP spoofing and traffic shaping to throttle the bandwidth of hosts on the network. This is explained in detail below.

This tool is the Windows GUI port of the original CLI tool Evil Limiter for Linux.

Requirements -- Windows 7 or higher

Missing requirements (including 3rd party applications, like Npcap) will be installed when running the setup.

The CompatTelRunner.exe file is located in the System32 folder and is owned by the TrustedInstaller any modifications you try to do to it will be met with an “Access is denied” error, which means that you can’t modify or delete it in any way. This is due to the fact that the process is owned by TrustedInstaller, and everything else only has a Read Only permission over it and you can’t modify it.

There is a solution for the issue, and it involves taking ownership of the process, after which you can delete it without deleting the entire Windows update and save yourself from problems OR you can let the program stay, and just disable Scheduled Tasks which launches the program.

taskschd.msc

Run as Administrator.

Expand Task Scheduler Library -> Microsoft -> Windows -> Application Experience

Right click on any of the tasks listed as Microsoft Compatibility Appraiser and choose Disable.

In practice, you never want to use the page file. //

The problem is that the default for automatically allocating the page file hasn't changed since Windows NT Server 3.5. It creates a page file that is 1.5 times the size of physical RAM. A good value when servers had 512 MB of RAM, but extremely wasteful on a server with 16 GB of RAM. That's a 24 GB page file! And did I mention that the default location for the page file is the C drive? With everything else that is vying for space on the C drive, the last thing you need is a gigantic file you never want to use. //

A good value for the page file is between 2 – 4 GB. Resist the temptation to make it any bigger than 4 GB, regardless of what "best practices" say. Remember, you never want to use the page file. And you only ever need one page file. Having multiple page files is even more wasteful than having a extremely large page file. //

Use a custom size for the page file and set the initial and maximum size to the same value. If these values are not the same, then the page file will become fragmented as Windows shrinks and expands the page file. You want to keep disk I/O operations for the page file to an absolute minimum, so let Windows create the page file once and keep it from constantly resizing it.

Disabling LSO on Windows Server 2008 and higher

This is easily done using a NETSH command:

 netsh interface tcp set global chimney=disabled

Disabling LSO on the Ethernet adapter

This works in all versions of versions of Windows Server since it's done at the driver level. Go to where the network adapters are located in the Control Panel. For Windows Server 2003, this will be under Network Connections. For Windows Server 2008, this will be under Network and Sharing Center –> Change Adapter Settings.

Now right-click on the network adapter and choose Properties from the pop-up menu. At the top of this windows will be a "Connect using" text field with the vendor and model of the network adapter. For my example, I'm using an Intel 52575 Gigabit adapter. Just below this text field, click on the Configure button.

Now click on the Advanced tab, which shows the configurable properties for the adapter. Find the entry for Large Send Offload. This is how it's labeled on Intel adapters, but will vary (sometimes wildly) for adapters from other other vendors. If it's modern adapter like this one, there will be a setting for both IPv4 and IPv6. For older adapters, there will only be a setting for IPv4. Change the value for Large Send Offload from "Enabled" (or "On") to "Disabled" (or "Off") and click on OK.

One issue that I continually see reported by customers is slow network performance. Although there are literally a ton of issues that can effect how fast data moves to and from a server, there is one fix I've found that will resolve this 99% of time — disable Large Send Offload on the Ethernet adapter.

So what is Large Send Offload (also known as Large Segmetation Offload, and LSO for short)? It's a feature on modern Ethernet adapters that allows the TCP\IP network stack to build a large TCP message of up to 64KB in length before sending to the Ethernet adapter. Then the hardware on the Ethernet adapter — what I'll call the LSO engine — segments it into smaller data packets (known as "frames" in Ethernet terminology) that can be sent over the wire. This is up to 1500 bytes for standard Ethernet frames and up to 9000 bytes for jumbo Ethernet frames. In return, this frees up the server CPU from having to handle segmenting large TCP messages into smaller packets that will fit inside the supported frame size. Which means better overall server performance. Sounds like a good deal. What could possibly go wrong?
