In this vein, I have been working during my spare time on various new utilities that use new undocumented APIs and expose the internals behind Windows Vista to discover more about how the operating system works, as well as to be able to provide useful information to administrators, developers, students, and anyone else in between. In this post, I want to introduce my latest tool, Mem. Info. Ill show you how Mem. Info can help you find bad memory modules RAM sticks on your system, track down memory leaks and even assist in detecting rootkitsOne of the major new features present in Windows Vista is Superfetch. Mark Russinovich did an excellent writeup on this as part of his series on Windows Vista Kernel Changes in Tech. I had a cbs. persist. Describes how to examine the small memory dump files that are created by Windows if your computer crashes. Depending on what type of memory dump file that you are trying to collect, the minimum size of the paging file will vary. Windows Server 2008 has three options for. Net Magazine. Because Superfetchs profiling and management does not occur at the kernel layer but rather as a service, by design choice, there had to be a new system call to communicate with the parts of Superfetch that do live in the kernel, just like Windows XPs prefetcher code, so that the user mode service could request information as well as send commands on operations to be performed. Heres an image of Process Explorer identifying the Superfetch service inside one of the service hosting processes. Because Superfetch goes much deeper than the simple file based prefetching Windows XP and later offer, it requires knowledge of information such as the internal memory manager lists, page counts and usage of pages on the system, memory range information, and more.

Detailed guide on how to manually Enable the missing System Restore feature on Windows Server 2008 R2 SP1. The new Superfetch. Information. Class added to Nt. QuerySet. Information. System provides this data, and much more. Mem. Info uses this API to query three kinds of information a list of physical address ranges on the system, which describe the system memory available to Windowsinformation about each page on the system including its location on the memory manager lists, its usage, and owning process, if anya list systemsession wide process information to correlate a process image name with its kernel mode object Mem. Info ultimately provides this information to the user through a variety of command line options described when you run the utility. Some of its various uses include Seeing how exactly Windows is manipulating your memory, by looking at the page list summaries. The Windows memory manager puts every page on the system on one of the many page lists that it manages i. Windows Internals covers these lists and usage in detail, and Mem. Info is capable of showing their sizes to you including pages which are marked Active, meaning currently in use and by the operating system and occupying physical memory such as working sets and not on any of the lists. This information can help you answer questions such as Am I making good use of my memory or Do I have damaged RAM modules installed. For example, because Windows includes a bad page list where it stores pages that have failed internal consistency checks, Mem. Info is an easy way but not 1. Windows internal checks might not have detected the RAM is bad to verify if any memory hardware on the system is misbehaving. Look for signs such as a highly elevated count of pages in the zeroed page list after a days worth of computer use to spot if Windows hasnt been fully using your RAM to its potential you may have too much or to detect a large memory deallocation by a process which implies large allocations previously done. Heres Mem. Info on my 3. Vista system, displaying summary page list information. Windows Vista also includes a new memory manager optimization called prioritized standby lists the standby state is the state in which pages find themselves when they have been cached by Windows various mechanisms are responsible for this of caching, including the cache manager and Superfetch and are not currently active in memory. Mark covered these new lists in his excellent article as well. To expose this information to system administrators, three new performance counters were added to Windows, displaying the size of the prioritized standby lists in groupings priorities 0 through 3 are called Standby Cache Reserve, 4 and 5 are called Standby Cache Normal Priority, and finally, 6 and 7 are called Standby Cache Core. Mem. Info on the other hand, which can also display these new lists, is an even better tool to identify memory in the standby state, since it is able to display the size of these lists individually. While memory allocations on Windows XP which could be part of application startup, the kernel mode heap, or simple memory allocations coming from various processes would consume pages from a single standby list and thus possibly steal away pages that more critical processes wouldve liked to have on standby, Windows Vista adds 8 prioritized lists, so that critical pages can be separated from less important pages and nearly useless pages. This way, when pages are needed for an allocation, the lower priority standby lists are used first a process called repurposing. By making snapshots of Mem. Infos output over a period of time, you can easily see this behavior. Heres Mem. Info output before, during, and after a large allocation of process private memory. Notice how initially, the bulk of my memory was cached on the standby lists. Most of the memory then became Active due to the ongoing large allocation, emptying the standby lists, starting by the lowest priority. Finally, after the memory was freed, most of the memory now went on the zero page list meaning the system just had to zero 1. GB of data. Seeing to what use are your pages being put to by Windows. Apart from their location on one of the page lists, Windows also tracks the usage of each page on the system. The full list includes about a dozen usages, ranging from non paged pool to private process allocations to kernel stacks. Mem. Info shows you the partitioning of all your pages according to their usage, which can help pinpoint memory leaks. High page counts in the driver locked pages, non paged pool pages andor kernel stack pages could be indicative of abnormal system behavior. The first two are critical resources on the system much information is available on the Internet for tracking down pool leaks, while the latter is typically tightly maintained for each thread, so a large number may indicate leaked threads. Other usages should also expect to see a lower number of pages than ones like process private pages, which is usually the largest of the group. At the time of this writing, heres how Windows is using my 4. GB of memory Looking at per process memory usage, and detecting hidden processes. Internally, Windows associates private process pages with the kernel executive object that represents processes as managed by the process manager the EPROCESS structure.
