win32k.pdb mismatched or not found - windbg

Question

I'm using PDB files provided by msdl.
Symchk and windbg were working fine till last week. But after an update (I think) suddenly I'm getting this message in symchk and every program which uses it.
Command: symchk.exe /v /r c:\windows\system32\win32k.sys /s SRV*c:\symbols\*http://msdl.microsoft.com/download/symbols
This is the verbose output of symchk:
[SYMCHK] Using search path "SRV*c:\symbols\*http://msdl.microsoft.com/download/symbols"

I tried deleting the symbols folder on my PC. no effect. I can get symbols for other files like ntoskrnl.exe. This command works like a charm on the latest windows 10; but occurs in windows 7. No other program like VS2017 and windbg can get the PDB files either.
