How do I determine the current version of LastPass Universal Proxy v4.x on Windows?

Problem

I do not know which version of LastPass Universal Proxy I am using.

Open PowerShell and execute the following command:
```
uproxy -version
```
The following is an example system output:
```
PS C:\Users\test> uproxy -version
LastPass Universal Proxy version: 2.2.0
```
If you cannot execute the previous command, go to the bin folder of the base directory (by default, C:\Program Files\LastPass\Universal Proxy\bin, check the version.bat file.
- If you cannot find the version.bat file, it means you have a version prior to 1.1.0.
- If you can find the version.bat file, run the file using the command line. As a result, the following message appears: LastPass Universal Proxy version: <version number>.
  
  The <version number> will show the version of the product.
