Unrestrict path length

In some cases it is necessary to unlimit the path length of Windows IoT.

This can occur, for example, if an OPC UA certificate with a too long file name is to be used.

To remove this limit, please follow these steps:

First click on Manage in the Peakboard Designer and select the menu item “Open Device Portal” for the corresponding Peakboard box.

Manage Dialog Open Device Portal

A browser window will now open. Enter “Administrator” as user name and the password of the Peakboard-Box.

Now select Processes on the left side and then Run command to see a command window in wich you can enter the following command:

Reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem /v LongPathsEnabled /t REG_DWORD /d 1 /f

Finally restart the box via Power – Restart.

Run Command Windows Device Portal
