A short time ago I solved following error: "Error 49: Volmgr. Conf page file for crash dump failed". Thanks to a guru here in this forum, he told me to enter into System/Advanced/Performance Settings/.../Virtual Memory Change, and check the “Automatically manage paging file size”. The error reporting stopped, everything OK so far.
However, after that moment my Vista uses extremely long time to shut down, up to 2 minutes. No error reports, nothing wrong as far as I can see, my Vista works perfectly well, and has a very quick start up. I tried to speed up the shut down time using a method I found in this forum, I entered into the registry and changed the WaitToKillServiceTimeout from 20000 to10000, but this did not help.
