Disable Certificate revocation list check when starting applications in Windows server
Since the Windows servers (2016) we are using don't have internet access, it would take very long time (10-30secs ) to open an application (Putty, Notepad++, Word, Excel, Adobe PDF reader and so on)....

I found that it kept checking application publisher's certificate by reaching out to CRL, since there's no internet access, it would fail and cause the delay in opening the application. I manually disabled XDR on the test server, and the delay never happened again.

thanks Harm_Veenstra It looks like it's related to XDR on the server.
