我運行蟒蛇過程管理員，并且可以創建新的鍵和值是這樣的：

import _winreg as wreg

key = wreg.CreateKey(wreg.HKEY_LOCAL_MACHINE, "Software\\TestCompany\\TestProject")

# Create new subkey

wreg.SetValue(key, 'NewSubkey', wreg.REG_SZ, 'testsubkey')

print wreg.QueryValue(key, 'NewSubKey')

# prints 'testsubkey'

# Create new value

wreg.SetValueEx(key, 'ValueName', 0, wreg.REG_SZ, 'testvalue')

print wreg.QueryValueEx(key,'ValueName')

# prints (u'testvalue', 1)

key.Close()

然而，當我重新打開相同的密鑰，并嘗試設置值，它給我一個Access is denied錯誤：

key = wreg.OpenKey(wreg.HKEY_LOCAL_MACHINE, "Software\\TestCompany\\TestProject",wreg.KEY_SET_VALUE)

wreg.SetValue(key, 'NewSubkey', wreg.REG_SZ, 'subkey_changed')

print wreg.QueryValue(key, 'NewSubkey')

# prints 'subkey_changed'

wreg.SetValueEx(key, 'ValueName', 0, wreg.REG_SZ, 'value_changed')

Traceback (most recent call last):

File "", line 1, in

wreg.SetValueEx(key, 'ValueName', 0, wreg.REG_SZ, 'value_changed')

WindowsError: [Error 5] Access is denied

print wreg.QueryValueEx(key, 'ValueName')

# still prints: (u'testvalue', 1)

key.Close()

>>> key = wreg.OpenKey(wreg.HKEY_LOCAL_MACHINE, "Software\\TestCompany\\TestProject",wreg.KEY_WRITE)

Traceback (most recent call last):

File "", line 1, in

key = wreg.OpenKey(wreg.HKEY_LOCAL_MACHINE, "Software\\TestCompany\\TestProject",wreg.KEY_WRITE)

WindowsError: [Error 5] Access is denied

>>> key = wreg.OpenKey(wreg.HKEY_LOCAL_MACHINE, "Software\\TestCompany\\TestProject",wreg.KEY_ALL_ACCESS)

Traceback (most recent call last):

File "", line 1, in

key = wreg.OpenKey(wreg.HKEY_LOCAL_MACHINE, "Software\\TestCompany\\TestProject",wreg.KEY_ALL_ACCESS)

WindowsError: [Error 5] Access is denied

我很想知道如何沒有管理員權限CreateKey。 –

@macdonjo：由于安全限制，我認為你不能這樣做，但你可以寫HKCU下的某些密鑰('HKEY_CURRENT_USER') –

是的，我最終做了CURRENT_USER。 –
