win32pdh.EnumObjectItems 调用错误
我在 Windows 7 中运行 Python 2.7，并安装了 pywin32-216-win32-py2.7。我正在运行以下代码，它在一台计算机上运行良好，但在另一台计算机上输出错误（Win7、Py2.7、相同的 pywin 库）。
错误信息：
文件“C:\Energy\Support Sheets\Kill Excel.py”，第 9 行，在 GetProcessID 中 项目，实例= win32pdh.EnumObjectItems（无，无，对象，win32pdh.PERF_DETAIL_WIZARD） 错误：（-1073738824，“缓冲区大小的EnumObjectItems”，“在计算机上找不到指定的对象。”）
完整代码：

import signal
import time
def GetProcessID( name ) :
object = "Process"
items, instances = win32pdh.EnumObjectItems( None, None, object, win32pdh.PERF_DETAIL_WIZARD )

hq = win32pdh.OpenQuery()
hcs = [ ]
item = "ID Process"
path = win32pdh.MakeCounterPath( ( None, object, name, None, 0, item ) )
hcs.append( win32pdh.AddCounter( hq, path ) )

I'm running Python 2.7 in Windows 7, with pywin32-216-win32-py2.7 installed. I'm running the following code, and it runs fine on one computer but outputs an error on another (both Win7, Py2.7, same pywin library).
Error message:

items, instances = win32pdh.EnumObjectItems( None, None, object, win32pdh.PERF_DETAIL_WIZARD )

当进程性能计数器被禁用时，我遇到了同样的问题 - 显然这可能会发生。有说明此处了解如何重新启用计数器。如果您无法在计算机上安装软件，您可以运行 regedit 并搜索名为“禁用性能计数器”的键并将其删除。
之后，您可能需要以管理员身份在 cmd shell 上运行“lodctr /R”以重新加载性能计数器，然后才能正常工作。
I had the same issue when the Process performance counter was disabled - apparently this can just happen. There are instructions here for how to re-enable the counters. If you can't install software on the machine, you can run regedit and search for keys called "Disable Performance Counters" and delete them.
After that, you may need to run "lodctr /R" on a cmd shell as Administrator to reload the performance counters before it will work.
手动重建性能计数器解决了我的问题，您可以使用以下步骤手动重建性能计数器并与 Windows Management Instrumentation (WMI) 重新同步
重建计数器：

Manually rebuilding the performance counters solved my issue, you can use the following steps to manually rebuild and resync the performance counters with Windows Management Instrumentation (WMI)
