Affected Products:

• Wyse 5070
• Wyse 5470 Mobile Thin Client
• Wyse 5470 All-in-One

Affected Operating Systems:

• Windows 10 IoT

By default, the unified write filter prevents wireless information from being persisted across reboots. Sometimes, this is not the wanted behavior.

To preserve wireless data:

1. Log in as the administrator.
2. Create a batch file on the administrator’s desktop.
3. Insert the following commands into the batch file:

@echo off

REM turn on UWF as exceptions cannot be added if UWF is disabled uwfmgr.exe filter enable

REM add required file and registry exclusions for Wifi profiles
uwfmgr.exe file add-exclusion "C:\ProgramData\Microsoft\dot3svc\Profiles\Interfaces"
uwfmgr.exe file add-exclusion "C:\ProgramData\Microsoft\wlansvc"
uwfmgr.exe file add-exclusion "C:\ProgramData\Microsoft\wlansvc\Profiles\Interfaces"

uwfmgr.exe file add-exclusion "C:\Windows\dot2svc\Policies"
uwfmgr.exe file add-exclusion "C:\Windows\wlansvc\Policies"

uwfmgr.exe registry add-exclusion "HKLM\SOFTWARE\Microsoft\wlansvc"
uwfmgr.exe registry add-exclusion "HKLM\SOFTWARE\Policies\Microsoft\Windows\WiredL2\GP_Policy"
uwfmgr.exe registry add-exclusion "HKLM\SOFTWARE\Policies\Microsoft\Windows\Wireless\GPTWirelessPolicy"

uwfmgr.exe registry add-exclusion "HKLM\SYSTEM\CurrentControlSet\services\dot3svc"

uwfmgr.exe registry add-exclusion "HKLM\SYSTEM\CurrentControlSet\services\Wlansvc"

uwfmgr.exe registry add-exclusion "HKLM\SYSTEM\CurrentControlSet\services\WwanSvc"

4. Save the batch file.
5. Right-click the batch file and then select Run As Administrator.
6. Reboot the device for the changes to take effect.
