Windows Administration

More to come eventually.

To be organized

  • Win7 ISO install under virtual box requries changing the following:

    VBoxManage setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1

    This apparently enables a 64-bit wide atomic compare and exchange instruction utilized in wait free locks under AMD64 and is required for Windows below 8.1. [Xref]

WinSxS

C:\Windows\WinSxS can quickly become large with many files. Apparently NTFS supports hard links and Windows will install all possible Windows Components and descriptor in this directory. Probably not a problem on modern servers with tons of disk space, however on EC2 with a 30GB drive losing 7GBs to WinSxS is sad times. To combat this problem we need to clean. Proceedure in the links below (need more Xref && details)
