How to use slmgr via PsExec?

Question

cmd/bat

You need to make a script for remote activation of Windows 7 via KMS.
3 commands are executed:

slmgr /skms ***
slmgr /ipk ***
slmgr /ato

Everything works locally. When trying through PsExec, the following happens:
- If I just connect to a PC ( psexec64.exe \\*** cmd.exe) and execute all these commands, everything works;
- If I write these commands in a batch file

psexec64.exe \\*** cmd.exe /с slmgr /skms ***
psexec64.exe \\*** cmd.exe /с slmgr /ipk ***
psexec64.exe \\*** cmd.exe /с slmgr /ato

Then at the stage of executing the first command, the execution hangs and does not react to anything, including Ctrl + C.
What am I doing wrong?
