Installing VMware Server or Workstation on Windows 7 will leave the __vmware_user\__ account showing on the logon screen, which does not happen in earlier versions of Windows.
If you want to hide this account, it’s a simple registry value addition:
- Open Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
- If it does not already exist, create a key named SpecialAccounts
- Below the SpecialAccounts key create another key named UserList
- Create a new DWORD value (DWORD32 on x64) inside UserList named __vmware_user\__ (the name of the account we want to hide) and ensure the value is 0
- Close Registry Editor and you are done – no need to reboot or logoff
To add this value a little quicker, paste the following command into an elevated command prompt and it will add the value for you
REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList" /v \_\_vmware\_user\\_\_ /d 0 /t REG_DWORD /f
