+  <summary>
+    Windows-only metric that represents the maximum amount of memory the current
+    process can commit. This value is equal to or smaller than the system-wide
+    available commit value.

+  <summary>
+    Windows-only metric that represents the amount of physical memory currently
+    available. This is the amount of physical memory that can be immediately
+    reused without having to write its contents to disk first. It is the sum of
+    the size of the standby, free, and zero lists.

+
+<histogram name="Memory.Stats.Win.AvailVirtual" units="MB">
+  <owner>georgseak@chromium.org</owner>
+  <summary>
+    Windows-only metric that represents the amount of unreserved and uncommitted
+    memory currently in the user-mode portion of the virtual address space of
+    the calling process.
+  </summary>
+</histogram>
+
+<histogram name="Memory.Stats.Win.MemoryLoad" units="percent">
+  <owner>georgseak@chromium.org</owner>
+  <summary>
+    Windows-only metric that represents the approximate percentage of physical
+    memory that was in use (0 indicates no memory use and 100 indicates full
+    memory use).
+  </summary>
+</histogram>
+
+<histogram name="Memory.Stats.Win.TotalPageFile" units="MB">
+  <owner>georgseak@chromium.org</owner>
+  <summary>
+    Windows-only metric that represents the current committed memory limit for
+    the system or the current process, whichever is smaller.
+  </summary>
+</histogram>
+
+<histogram name="Memory.Stats.Win.TotalPhys" units="MB">
+  <owner>georgseak@chromium.org</owner>
+  <summary>
+    Windows-only metric that represents the amount of actual physical memory.

+
+<histogram name="Memory.Stats.Win.TotalVirtual" units="MB">
+  <owner>georgseak@chromium.org</owner>
+  <summary>
+    Windows-only metric that represents the size of the user-mode portion of the
+    virtual address space of the calling process. This value depends on the type
+    of process, the type of processor, and the configuration of the operating
+    system. For example, this value is approximately 2 GB for most 32-bit
+    processes on an x86 processor and approximately 3 GB for 32-bit processes
+    that are large address aware running on a system with 4-gigabyte tuning
+    enabled.
