Improving the reg function and adding a new reg.exists, reg.get, reg.set, reg.delete functions.

The first parameter, which is the root key, was combined with the subkey path into one parameter to be compatible with REG COMMANDS.

The keyname must include a valid root key. Valid root keys for the local computer are:

HKCU
HKCR
HKLM
HKU
HKEY_CLASSES_ROOT
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE
HKEY_USERS

REG.EXISTS

reg.exists('HKCU\Control Panel\Desktop')

reg.exists('HKCU\Control Panel\Desktop', "WallPaper")

REG.GET

Read data by value name

reg('HKCU\Control Panel\Desktop', "WallPaper")
reg.get('HKCU\Control Panel\Desktop', "WallPaper")
reg.get('HKCU\Control Panel\Desktop')

reg.set('HKCU\Software\Nilesoft\Shell', "test-str", 1, reg.sz)
reg.set('HKCU\Software\Nilesoft\Shell', "test-str", 'some string', reg.sz)

Set value data with auto type detection

reg.set('HKCU\Software\Nilesoft\Shell', 'test-auto-int', 1)
