I recently upgraded from Win10 to Win11 25H2.
But so far, I have not seen an issue with LPCScrypt (yet). Using the one packaged with LinkServer v25.9.134 (see below)
Updating my LPC-Link2 with LPCScrypt worked fine.

Not an expert on WMIC, but according to the information it is gone in 25H2, chatGTP suggested to copy wmic.exe and wmic.exe.mui from an older Windows version to 25H2.
NXP is aware of the issue, and there might be an updated LPCScrypt in a next LinkServer release.
