For some unknown reason (maybe system architecture difference, say you are trying to connect to a 32-bit OS shared printer with a 64-bit client) you may get this error code, here is a trick to save your life.

1. Make sure you have saved credentials for that shared printer, simplest way to this is type \\IP_ADDRESS or \\Machine_Name of that host, enter and save credentials if you are not in AD.
2. Add a local printer for same type and driver version you are trying to connect to, use LPTx or COMx as port number when required, atfer installation, you should have a printer in you Control Panel> Devices and Printers.
3. Type \\IP_ADDRESS or \\Machine_Name of print host machine, and another backslash \ then you will get a dropdown list showing all resources on that host, use downwards arrow on your keyboard to navigate to the printer you are tring to connect. select full path in address bar and copy it like this:
4. Navigate to Control Panel> Devices and Printers, open Printer Properties of that new printer you have just installed locally, in tab Port, click Add Port, then add a *LOCAL PORT*, in name box, paste full path to that printer you have copied then click Apply or OK all the way. 
5. You are saved.

64位win10连32位win10下共享出来的打印机，死活连不上，一直报错，百度、bing甚至google都没找到任何有效信息，后来想起来很多年前用过的一个trick，方法如下：

先在资源管理器（如我的电脑之类的窗口）中，连接到相应的电脑，敲\\IP或者机器名，并保存用户名密码（记住凭据），域环境请无视

确保能显示对应机器的资源后，回到控制面板>设备和打印机>添加打印机

自行下载相应添加的打印机的驱动并按照安装本地打印机的流程安装，如果要选择打印机端口，选LPT1或者COM1之类的都可以

或者更简单一点的方法：把打印机直接插到本地电脑用任意方法（如驱动精灵、windows更新、XX卫士、XX助手等等）安装驱动后把打印机插回原位。驱动安装完成后，开始骚操作

先打\\IP或机器名，然后再加一根斜杠“\”，就能看到机器上的资源列表，用键盘上下键选中需要添加的打印机完整路径并复制

然后回到设备和打印机，打开刚才安装的打印机的打印机属性页，在端口页面，添加端口，类型选择默认的本地端口（Local Port），然后点新端口，端口名就是刚才复制的打印机完整路径，确定，完工

这一招从xp年代开始就能应对各种奇奇怪怪的无法添加共享打印机的状况，至今仍然适用

快速访问固定了不少常用文件夹，无法使用很蛋碎

尝试了清历史记录，设置里禁用显示最近使用和常用文件夹，还是不行，最后无意间看到资源监视器里一直在读写莫个文件，想起来尝试下，就动手干掉了下面这个文件夹的所有内容

%userprofile%\AppData\Roaming\Microsoft\Windows\Recent\AutomaticDestinations

然后就没有然后了
