Windows 7: The Page file

The Page file

I would like to give my thoughts about the Page file and would like some thoughts about it from some of the other members. I could be wrong on my assessment but would like some other opinions. My laptop computer is running Windows 7 64 bit. I have 8 gig of ram installed. As far as the Page file is concerned, I had it set so that Windows controls the size which was 8136MB. First of all, it boggles my mind why Windows wants that big of a file simply to use it to write logs. Second, there are two potential problems with the Page file: First it can become corrupt which could cause problems. Second, it could become a security issue. I have therefore edited the registry so that it clears the file on shutdown. The only drawback is that it takes a long time to shut down since it has to clear the file. My computer would take 3 minutes to shutdown. I therefore set the Page file at 50 MB which I think is large enough. Now it takes only 1 1/2 minutes to shutdown. I'm going to leave it like that. I would appreciate it if we could have some discussion on what I have said. Thanks

The discussion is, you are spending too much time and effort worrying about something that isn't really worth it. There are far more worrisome security issues than a pagefile, and corruption isn't really an issue. I can't say I've heard of that in a long long time.

It boils down to this. Your first option is to leave it alone and let Windows manage it. If you are using a small SSD and need more space, set it to a static size of 2 GB. Don't worry about clearing it on shutdown. Then go on using your system for it's intended purposes.

Deacon is exactly right. That's what I do on all my systems because they all run on small SSDs. 1 or 2GB is enough for the pagefile and clearing it at shutdown is for the birds.

The page file (virtual memory) is not for writing logs. If you have 8GB of RAM, you probably don't need 8+ GB of a page file but if it is too small, memory dump files, for diagnostics, will not be available in case of asystem crash.

What is virtual memory?

You can tell Windows to encrypt the paging file.

So if people uses encryption to protect data on their harddrive, you don't find any problems by having it leak to the paging file?

Isn't the "memory dump file" a log file?

Think about the question you asked me and you'll see very quickly why this is a non-issue.

Yes it is but it is not stored in the page file (virtual memory). The system uses the page file to create the memory dump and stores it in C:\Windows.

Thanks, I didn't know that.
