After some experimentation I found that symchk change LAT, it was what I needed to free space after an update:
so I start like the following line
symchk.exe /r c:\Windows\*.dll /s srv*d:\pdbs /op
and change the pdbs' files LAT to all files not touched the update

After that I start the age_store (by the way I have changed the PROMPT (c_m_d) environment variable to the new prompt without symbol "gt" (when copy-pasted those can be interpreted as "the following is file name, so overwrite it"
"REM" — comments

REM │2017-01-20 5:23 Microsoft Windows [](+)
REM d:\pdbs
REM └agestore.exe D:\pdbs -days=60 -s

Now download the new symbols (pdb-files)
symchk.exe /r c:\Windows\*.dll /s srv*d:\pdbs*https://msdl.microsoft.com/download/symbols /op
