First, introduce the basic knowledge of the registry: each folder in the registry is called a key (item), and the subfolder of this folder is called the subkey (sub

Getting Started with PHP design mode-Registry mode
The scenario for this pattern is not too good to summarize, but based on previous experience, the registry class often stores objects that need to be used elsewhere, such as Redis, memcache classes, and so on, such as configuration information Config class, which acts as a role similar to global variables. The actual implementation is very simple, as shown
When you don't need to get the registry data type and as long as the value is very simple: you can use Get-itemproperty:
Copy Code code as follows:

If you need to get the data
remote computer. So you need to use WMI. Then, guess what happens: if you use WMI to try to read a nonexistent value, no error will occur. Instead, WMI continues to run as if no errors occurred. It's hopeless.
But then we found something. When you use WMI to read the registry, this value is returned as an "output parameter." When we examine the actual value of this output parameter, we find that if the value you are trying to read does not exist, you

Many scenarios are using GetVersion, GetVersionEx these two APIs to query the operating system version number to determine the current operating system is the Windows family which, before the Win10, this method is the line of the pass, But after the appearance of Win10, this method is not allowed to judge Win10.Here is a way to read the registry, which has been verified to be feasible:[CPP]View PlainCopy

Our general procedure for the operation of the Registry is to open, read, and close, then first take a look at some of the most important functions of the introduction bar, the other more functions are to be accessed by the MSDN.
First of all, turn on and off function, before reading and writing the registry, you must first open the target's subkey, that is, to obtain an operation of the handle, and open th
In the previous tip we explained how to convert a PS-built path format into a real path. An example is presented here. This code recursively obtains from HKEY_CURRENT_USER all the keys that contain the "PowerShell" affix (a simple substitution query affix will get anything you want to query)
