##### OS / ENVIRONMENT

##### STEPS TO REPRODUCE
<!--- Describe exactly how to reproduce the problem, using a minimal test-case -->

<!--- Paste example playbooks or commands between quotes below -->
Case original:
```
C:\Windows\system32>net share EAI
Share name        EAI
Path              D:\Partage\EAI
Remark            Repertoire EAI
Maximum users     No limit
Users
Caching           Manual caching of documents
Permission        VSRVQSRM\Appli_Urba, FULL
                  PAM\EXP_TRT, READ
```
I manually added PAM\EXP_TRT with READ rules.

I run playbook like this:
```
- name: Add share EAI
  win_share:
    name: EAI
    description: Repertoire EAI
    path: D:\Partage\EAI
    list: no
    full: Appli_Urba
  when: ansible_distribution_version is version('6.2','>=')

```
This remove the created user
