Application Sharing in multiple systems

In this era of Windows operating systems and Linux and Unix operating systems "Flood", everyone has been addicted to operating systems. This is especially true for many DIY enthusiasts, for example, I have now installed three Win systems, some games have to run under ME or broken bar. I want to enjoy playing games more deeply than others, and some software, especially the 16-bit ntvdm running in 2 K and XP Virtual Environments is not good. For example, if TC30 + + runs in 2 K and XP, the good CPU is 100% of the burden; 2 k is his stability, security, and multi-user management; XP is pure play, but it is still in the trial, haha ). Therefore, first, multiple systems are just about playing games. For DIYER, that is, the spirit of exploring DIYER and satisfying DIY. Second, you can also learn a lot of things, familiar with some operating systems is also very convenient for looking for work in the future. If you write "skilled in operating a variety of operating systems" in your cover letter, I am afraid Boss will also look very interested in you: P.

Let's talk about the Win series.

Since each system has the advantages of each system, the Big Bird and the bird who have installed several systems may have encountered this problem: the problem of installing the same application in multiple systems. Many people have to install several repeated software in multiple systems. This may not matter for prawns and cainiao with relatively large hard disks. However, for me and the poor, I have to check whether there is money in the purse. Therefore, I have tried several times to find that this problem can be solved using the following methods:

1: Repeated installation in several systems, but the installation path is located in the same folder, which can save a lot of space. However, there are several problems in this way. First, installation is annoying. there are always a few identical programs to install. If it is a relatively large program, these programs may be installed, second, because after each program is installed, it will install the program group corresponding to the application in the program group. Of course, there will be the Uninstall tool, if you accidentally press or intentionally Uninstall a system, when you use another system, you will smile at the system for your "lack of shortcuts". At the same time, you will inadvertently inject a lot of registry garbage into your system, affecting the running speed and even stability.

2: do not install it in other systems, but register it. We know that most software must be registered in the registry after installation, and we can also find that in the folder corresponding to C: Program Files (default installation location, almost all of them have one or several registry files. reg is a suffix file), as long as we run these registration files, then the registration confirmation dialog box will pop up as long as we click yes or OK to register the software in the registry, in general, there are still a lot of applications that can be dealt with in this way, fast and convenient. It is better than the first one. 3: Install it once, once and for all. This is for many "green" software. In fact, there are still a lot of applications that can be directly used in the Windows system that require installation and registration. The reason for this installation is to make it easy for users, for example, you can set up corresponding program groups and shortcuts in [start] [programs], and create shortcuts on the desktop to make them easy to use. these software didn't install anything mysterious in the system. In particular, some software, we can even use winzip, winrar, and other decompression tools to decompress the package directly. In this case, we can copy the folder of the corresponding Program to the C: Program Files directory after a certain installation and put it on another disk, such as disk D and disk E, after reinstalling the system in the future, you can directly use it instead of installing the system (it is more convenient to create a shortcut later, so you can enjoy it :)). In fact, there are quite a lot of such green software, such as QQ, Editplus, UltraEdit, LeapFtp, Realplay, Cterm popular on bbs, and Flash, Dreamweaver, and Dreamweaver. ultraDev ., firework and so on are all such "green" software (the reason for quotation marks is that some of them still need to be installed before they can be copied for use), and, many Games use this kind of "green" software.

Everyone is clear. Let's make a comparison and choose one. Should I leave it alone?

Of course, sometimes we will still encounter some troubles, such as the prompt saying that the DLL file cannot be found. At this time, we seem to have to install it again. In fact, it is not necessary because we only need to modify some system parameters to easily solve the problem. This is especially simple in Win2K. on the desktop, right-click my computer and choose properties. The system features dialog box is displayed, select the [advanced] column. We can see the [performance] [environment variables] and [start and fault recovery] Columns. Click [environment variable (E )...] The "environment variables" dialog box appears ,.

The preceding dialog box sets the environment variables of the current user. The settings are only valid for the current user. The following are system variables, which are valid for all users using this computer, generally, you must have the administrator privilege to set or modify the environment. (the so-called environment variable is the environment during system running, such as the location of the Linked Library and dll ). In most cases, we only need to set the Path variable (if there is no such variable, we can create one ourselves) to flat it. Generally, set Path to the Path of the folder where another system is located and the Path where the program is located. If not, pay attention to the file name in the warning, if you search this file again, you can always find its path: P. In fact, Windows systems based on the NT structure can be modified in this way. For 98 and so on, it should be available in Autoexec. set the Path in bat. I have never done this. Please give me some advice.
