批处理脚本在文本文件中搜索字符串;(Batch script to search strings in text file; echo string found or not found)

 我需要一个CMD脚本，它能够基于findtr命令来搜索文本文件，该命令有多个字符串可供搜索。 
 
 
 在这种情况下，我创建了一个包含命令结果的文本文件（kb.txt） ： 
 
wmic qfe list
 
 我需要的脚本将读取文件并使用findstr命令搜索它，如下所示： 
 
findstr "kb3199321 kb3175631 kb3155567 kb3143345"
 
 如果未找到该字符串，则会输出未找到的字符串。 对于那些已经找到的人也是如此。 输出示例： 
 
kb3199321 not found
kb3175631 found
kb3155567 found
kb3143345 not found
 
 脚本应该遍历所有字符串的findstr命令（不仅仅是上面列出的4个，它可能是几十到几百个），并且对于它们中的每个字符串，如果找到该字符串，则回显。 
 
 
 注意 
 
 如果findstr命令太有限（无法搜索超过一百个字符串），那么脚本应从另一个单独的文本文件（例如“searchfile.txt”）中读取所有字符串，然后搜索“ kb.txt“来查看它是否能够找到字符串，并回显与上面相同的想要的结果 

I need a CMD script that is able to search through a text file based on a findstr command that has multiple strings in it to be searched for.
 
 
In this case, I have created a text file (kb.txt) that contains the result of the command: 
 
wmic qfe list
 
The script I need will read the file and searches through it with the findstr command like:
 
findstr "kb3199321 kb3175631 kb3155567 kb3143345"
 
If the string is not found, it will output the string that is not found. The same goes for those that have been found. Example of output:
 
kb3199321 not found
kb3175631 found
kb3155567 found
kb3143345 not found
 
The script should loop through the findstr command for all its strings (not just the 4 listed above, it could be a few dozen to hundreds), and for each of them, echo if the string is found or not.
 
 
Note
 
If the findstr command is too limited (where it can't search through more than a hundred strings), then the script should read off all the strings from another separate text file (e.g. "searchfile.txt"), then search through the "kb.txt" to see if it is able to find the strings, and echo the same wanted results as above
