Hello folks,

I've found a small tool which uses the same sequence for granting
'SeLockMemoryPrivilege'. Good for testing because it actually calls
'LsaEnumerateAccountRights' later which deserves own bug.

There are 3 requirements for large (and locked) pages to work on Windows:

1. You need to have the "SeLockMemoryPrivilege" token. This privilege is
disabled for all users by default. You will need to enable it manually.
2. y-cruncher needs to be running as an administrator.
3. There needs to be enough contiguous physical memory in the system.

Enabling SeLockMemoryPrivilege:

"SeLockMemoryPrivilege" is disabled for all users by default. So you will
likely need to enable it manually.

Instructions for enabling it using the Group Policy Editor can be found here:
https://msdn.microsoft.com/en-us/library/ms190730.aspx

If your version of Windows is a Home Edition and does not have the Group Policy
Editor, you can also enable it by running the following program:

Enable "SeLockMemoryPrivilege" on Windows:

* Precompiled Binary
* Source Code

Run y-cruncher as an Administrator:

Right-click the program and select "Run as administrator". You may get a UAC
warning depending on your settings.
