如何彻底卸载NoMachine

问题:

For what ever reason NoMachine will not work on my Network. I cannot log onto the remote PC no matter what. I know my Password is correct but no matter what it will not let me access the Remote PC. I get 4 different error messages and then finally it lets me try to log on but it rejects the correct password every time. I need to complete a Clean Uninstall as each time I try to Reload NoMachine it still holds the previous details so I have no way to start from new.

 

回答:

After you’ve removed NoMachine “Programs and Features” and rebooted the machine (like indicated in the “Installation Guide” https://www.nomachine.com/DT07M00078#2.3.) remove directories related to nxplayer configurations i.e., .nx (in default: C:/Users/<username>/.nx) and to connection files of NoMachine (default path: C:/Users/<username>/Documents/NoMachine).

TeamViewer 与 RDP 有什么区别?

概述

RDP(远程桌面协议)是 Microsoft 开发的用于连接远程计算机的协议。

TeamViewer 的功能远远超出 RDP 的功能。

区别

两者的一些主要区别包括:

  • 当与 RDP 连接时,其不允许被远程连接计算机的本地用户查看或控制其屏幕,这意味着远程用户不知道您在他们的计算机上正在进行哪些操作。TeamViewer 允许远程用户查看您在他们屏幕上进行的所有操作,这一点对于为客户或朋友/家人提供远程支持至关重要。
  • RDP 要求您在远程计算机的防火墙或路由器上配置端口转发。TeamViewer 无需端口转发或其他防火墙配置。
  • TeamViewer 拥有更强大的平台支持:您可以使用 TeamViewer 与 Windows、macOS、Linux、Chrome OS、Android、iOS、Windows Mobile、BlackBerry 和 Raspberry Pi 互连。

另外,如果您有用户使用 RDP 登录 Windows Server,则可以使用 TeamViewer 直接连接到每位用户的 RDP 会话,为其提供支持。当 TeamViewer 在 Windows Server 上运行时,它会为每个 RDP 会话生成一个唯一的“用户 ID”,以便您可以连接到该 RDP 会话并帮助该用户。它还会生成一个“服务器 ID”,当您需要在服务器上工作时,可以用该服务器 ID 直接连接服务器控制台。

How to download a Windows 10 ISO file legally and install Windows 10 from it

Whether you currently use Windows 10 and want the latest version or you want to switch from another operating system, it’s possible — but there may be some confusing steps. Downloading and installing the Windows 10 ISO file allows you to install the latest Microsoft OS.

If you don’t know how to download and install a Windows 10 ISO file, we cover the basics. Keep reading to learn what you need to do.

Step 1: Download the Windows 10 ISO legally from Microsoft on Windows

windows-10-tool-create-media

To get started, head to the Windows 10 download page and click the blue Download Tool Now button. If you’re on a computer running Windows 7, 8, or 10, use the Windows 10 Download Tool. If not, refer to step 2 below.

This tool makes it easy to turn any USB key into a bootable Windows 10 installer and allows you to download the Windows 10 ISO file for future use. When the tool downloads, run it. You must then confirm whether you want to upgrade your current PC or create installation media for another PC.

Select Create Installation Media For Another PC, as shown above, and then click Next. Select the language, architecture, and edition of Windows you prefer. It’s usually best to check the box for Use This Recommended Option For This PC, but you can also customize and choose a different Windows edition, such as Windows 10 Pro or Home.

Next, if you’re looking to install Windows on your PC, select the ISO File Option. Doing so will save a file that you can click later (step 3) to upgrade your PC to Windows 10. You also can use the ISO to burn Windows 10 to a DVD, if you please — in that case, skip ahead to step 4.

Otherwise, if you want to create a USB Flash Drive, select the USB Flash Drive option. Doing so will allow you to create a bootable USB drive that you can use to erase everything from your computer and go for a “clean install.” This USB drive can be used on other computers to install Windows. With this option, choose your USB drive and have Windows 10 downloaded to it. Be warned: Everything on the drive will delete before installation, so make sure no crucial files become lost.

windows-10-save-iso

For most people, the ISO file is the safest method. When you Select ISO File, click Next, and select where to save the ISO file. Once the download is complete, you will have the ISO file on your computer’s hard drive. You can continue to step 3 for more.

Step 2 (optional): Downloading the Windows 10 ISO from Microsoft on Mac, Linux, and Windows Vista/XP computers

windows-10-iso

The Windows 10 Download Tool only works on computers running Windows 7, 8, or 10. If you’re not running one of those operating systems, you can still download the Windows 10 ISO from Microsoft. Just head to the Windows 10 download page, and it will detect that you’re not running a compatible OS.

From this page, you can pick which version of Windows 10 to download — either 32-bit or 64-bit ISO — in your language of choice. You can then copy the ISO file to a USB stick and bring it over to a Windows laptop or desktop to proceed with the installation.

Step 3: Install Windows 10 directly from the ISO from within Windows 7 or 8/8.1

windows-10-mounted-iso

If you’re running Windows 8 or newer, you can upgrade your PC or laptop to Windows 10 by mounting the ISO file you just downloaded — double-click it. Windows will display the ISO as though it is a DVD drive.

From here, you can install Windows 10. Just open Setup.exe, and the installer will open. From here, you can choose to install Windows 10 in place, leaving your files and programs. All necessary data will transfer from the ISO to your computer, which will eventually restart your PC to complete the installation.

If you’re running Windows 7 or earlier, you can’t mount ISOs — instead, you can download Virtual Clone Drive and use that to install ISO files. Once you’ve got the drive mounted, the installation will work the same as outlined above. You also can try the Windows 10 Upgrade Assistant to upgrade from Windows 10. We have a guide for that here.

Step 4: Burn the Windows 10 ISO to a DVD

windows-disk-burner-iso

If your computer has a DVD burner and you’ve got a writable DVD on hand, you can burn the Windows 10 ISO to a DVD and install Windows 10 by booting from it. Right-click the ISO file, then click Burn Disc Image. The Windows Disc Image Burner will open, asking you which drive you’d like to use.

When ready, click Burn to start the process. When it’s complete, you’ll have a bootable DVD that you can use to install Windows. You can use other software to burn your ISO, but the built-in software is simple enough to use.

Most computers should boot from DVD by default, but sometimes you may need to access your computer’s boot menu to install Windows 10 from DVD. Annoyingly, this requires a different keyboard shortcut on other devices. Still, if you pay attention when your computer is starting up, see the instructions for accessing the boot menu.

Other uses for the Windows 10 ISO file

There are plenty of other uses for a Windows 10 ISO file. For example, you may want to install Windows 10 on your Mac or set up Windows 10 in a virtual machine application. In either case, the ISO file is the preferred tool for installing Windows 10.

You will need a valid Windows 10 product key to install Windows 10. On computers currently running Windows 7 or Windows 8/8.1, this isn’t a problem. You can upgrade in-place, and Windows 10 will detect your previous license. Failing that, you can use the product key on your device — look for a sticker.

The free ISO file isn’t a free Windows license. It’s just a more convenient way to install Windows 10. Mac users, custom PC builders, and anyone installing on a virtual machine will need a product key to legally install Windows 10. They can buy Windows 10 Home for $139.

11 Best Tools to Access Remote Linux Desktop

Accessing a remote desktop computer is made possible by the remote desktop protocol (RDP), a proprietary protocol developed by Microsoft. It gives a user a graphical interface to connect to another/remote computer over a network connection. FreeRDP is a free implementation of the RDP.

RDP works in a client/server model, where the remote computer must have RDP server software installed and running, and a user employs RDP client software to connect to it, to manage the remote desktop computer.

In this article, we will share a list software for accessing a remote Linux desktop: the list starts off with VNC applications.

VNC (Virtual Network Computing) is a server-client protocol which allows user accounts to remotely connect and control a distant system by using the resources provided by the Graphical User Interface (GUI).

Zoho Assist

Zoho Assist is a free, fast, cross-platform remote support software that allows you to access and support Linux desktops or servers without remote connection protocols like RDP, VNC, or SSH. Remote connections can be established from your favorite browser or a desktop plugin, regardless of the remote computer’s network.

With a whole host of features like remote file transfer, multi-monitor navigation, and clipboard sharing to aid MSPs, IT support technicians, and helpdesk technicians, debugging a Linux remote desktop is easy sailing with Zoho Assist.

Zoho Assist is extremely secure with two-factor authentication, action log viewer, and antivirus compatability. SSL and 256-bit AES encryption ensures all session-related information is passed through an encrypted tunnel.

A clutter-free user interface makes working easy for first-timers. You can customize email templates, and rebrand the Linux remote desktop application to use your company’s name, logo, favicon, and portal URL.

With Zoho Assist, you can configure all major variations of Linux computers and servers like Ubuntu, Redhat, Cent, Debian Linux Mint, and Fedora for unattended access, and seamlessly access them anytime.
