 Running DPDK Applications
 =========================
 
+Grant *Lock pages in memory* Privilege
+--------------------------------------
+
+Use of hugepages ("large pages" in Windows terminology) requires
+``SeLockMemoryPrivilege`` for the user running an application.
+
+1. Open *Local Security Policy* snap-in, either:
+
+   * Control Panel / Computer Management / Local Security Policy;
+   * or Win+R, type ``secpol``, press Enter.
+
+2. Open *Local Policies / User Rights Assignment / Lock pages in memory.*
+
+3. Add desired users or groups to the list of grantees.
+
+4. Privilege is applied upon next logon. In particular, if privilege has been
+   granted to current user, a logoff is required before it is available.
+
+See `Large-Page Support`_ in MSDN for details.
