Ever wondered what type of RAM your PC uses and if there is a bank available to add more? Ask WMI! This example also converts the cryptic type codes into clear-text using hashtables to create new columns:
$memorytype = "Unknown", "Other", "DRAM", "Synchronous DRAM", "Cache DRAM",
"EDO", "EDRAM", "VRAM", "SRAM", "RAM", "ROM", "Flash", "EEPROM", "FEPROM",
"EPROM", "CDRAM", "3DRAM", "SDRAM", "SGRAM", "RDRAM", "DDR", "DDR-2"
$formfactor = "Unknown", "Other", "SIP", "DIP", "ZIP", "SOJ", "Proprietary",
"SIMM", "DIMM", "TSOP", "PGA", "RIMM", "SODIMM", "SRIMM", "SMD", "SSMP",
"QFP", "TQFP", "SOIC", "LCC", "PLCC", "BGA", "FPBGA", "LGA"
$col1 = @{Name='Size (GB)'; Expression={ $_.Capacity/1GB } }
$col2 = @{Name='Form Factor'; Expression={$formfactor[$_.FormFactor]} }
$col3 = @{Name='Memory Type'; Expression={ $memorytype[$_.MemoryType] } }
Get-WmiObject Win32_PhysicalMemory | Select-Object BankLabel, $col1, $col2, $col3

想知道你电脑内存的类型或者是否还有插槽能让你再加条内存呢？通过WMI!，这个示例通过哈希表的形式把类型代码转换成明文的形式：
$memorytype = "Unknown", "Other", "DRAM", "Synchronous DRAM", "Cache DRAM",
"EDO", "EDRAM", "VRAM", "SRAM", "RAM", "ROM", "Flash", "EEPROM", "FEPROM",
"EPROM", "CDRAM", "3DRAM", "SDRAM", "SGRAM", "RDRAM", "DDR", "DDR-2"
$formfactor = "Unknown", "Other", "SIP", "DIP", "ZIP", "SOJ", "Proprietary",
"SIMM", "DIMM", "TSOP", "PGA", "RIMM", "SODIMM", "SRIMM", "SMD", "SSMP",
"QFP", "TQFP", "SOIC", "LCC", "PLCC", "BGA", "FPBGA", "LGA"
$col1 = @{Name='Size (GB)'; Expression={ $_.Capacity/1GB } }
$col2 = @{Name='Form Factor'; Expression={$formfactor[$_.FormFactor]} }
$col3 = @{Name='Memory Type'; Expression={ $memorytype[$_.MemoryType] } }
Get-WmiObject Win32_PhysicalMemory | Select-Object BankLabel, $col1, $col2, $col3
笔记：
复习WMI的查询操作。
学习如何声明一个显示列。
WMI真是万能。
