Can debug information from paging file be useful after system crash?

If you try to delete paging file you will see a warning that system needs 400 MB free space for debug information if system crashes. Does it really do smth? Does it help to restore system? Does it influence on next reboot after crash and successful result of rebooting?
DO I REALLY HAVE TO USE PAGING FILE FOR THAT?!
P.S. Yes I know that programs may stop working without it but the question is about that warning.

 

If the paging file is disabled you will most likely not be able to retrieve a debug file after a system crash, yes.

But as I already told you - if you feel your system benefits from a disabled pagefile like mine, I don't know why you are afraid of loosing a debug information after a system crash!?

1. Obviously you have no idea what to do with a debugging file
2. If your system crashes often - you certainly need to find a solution before doing any speed modifications
3. If it happens to crash you can enable the pagefile back again and await another crash - if it doesn't happen you can call it a day, grab a beer and disable the pagefile again. And if it does happen - you will get your debugging information for whatever purpose you think it could help you.

 

you can turn off system debugging completely or just set it to write a mini-dump.

 

Looks like you are persistent I am not like thinking about disabling/enabling paging file but more like to find out what it gives and "have idea what to do with it". I have 3 dmp files and 3xml files each pare of 1 crash. xml files give only info about systems devices and their drivers (sysdata) while dmp files look encrypted in notepad. And I do not even know if I would got them If my paging file had been deleted.
P.S. for 5 month being a member of this forum I got so much knowledges even without special searching them. But if I'd avoided everything I did not know I would still think that notebookreview is a forum of only high-level IT specialists and I am like a child against adult writing to them

Looks interesting. Please continue Besides my dmp files are 256KB files. What size have minidump files then?

 

they are not encrypted, just binary information most likely the actual memory map dump which is only useful for Microsoft. With luck, it is possible to fish your secret out of it as not all programs give a hard thought about security(they would usually not saving password etc. using backing device like a file but very likely to keep them in memory unencrypted).

This is another added benefit of not using page file. Though this problem can be mitigated using full disk encryption like truecrypt or bitlocker.
