Want to open your computer file a bit faster? There is how

What do you know about compression feature of Windows? This feature helps you to compress file and force them to occupy a smaller space in the hard drive but leave, but it will keep the compressed file stay in their native format. This technology is widely use in Windows OS, and we found that using NTFS compression not only save your computer drive space but also increase your hard drive performance. Here I’ll show you how to compress file and directory to let you gain better system performance, especially file open speed. (FYI: this method is not feasible with SSD drive computer)

To experience the maximum performance increase, you’ll need to compress the following directories:

• Users (Documents and Settings in Windows XP)
• Program Files
• Program Data (Windows Vista and Windows 7)
• Windows
• All your .exe and .dll files

NTFS file compression is done through the Command Prompt with a simple command: compact /c /s /i. Before you open the Command Prompt, make sure that you are logged in as administrator.

OK, let’s get started!

1. Click on Start, type cmd in the Search box (Run box in Windows XP) and press Ctrl+Shift+Enter.

Software uninstallation on Windos8 system

msft-vs-apple2
In Win8 system, it’s more convenient and more compact to uninstall the program or software compared to Win7 and XP system, where we can not only uninstall the program in the traditional interface, in the third-party, even we can also uninstall in the Metro interface, below I share some Win8 uninstallers.

Tools / materials:
Laptop, windows8.1 system

Method 1
1. First, we enter to control panel, find “Programs and Features”, double-click to enter, then we can see the programs has been installed, you can double-click to uninstall whatever you want. You can also right-click the pop-up “program Uninstall / Change” and then uninstall it.

2. Right-click “Win icon” in the lower left corner, computer information will pop up, where we can see the “Control Panel”, click to enter. In the lower left corner of the control panel we can see the “Programs / uninstall”, click on “Uninstall a program” below the “Programs” to enter into the “Uninstall or change program.” Find the program you want to uninstall, double-click or right-click to uninstall in the “program Uninstall / Change”.

3.Of course, we can mouse over the desktop right corner “Charm Toolbar”, down to select the device. Here we can also find the same control panel.

Method 2
Third-party software to uninstall program is actually the best way which is way more convenient and fast. Today’s computer security guards basically have the uninstaller feature with various classification includes software name, software size, installation path and usage.

Method 3
Use Metro application to uninstall. Not only the .exe program we installed can be found in Metro application, also a visual program to uninstall option. In the program you want to uninstall bar you can seen “Program Uninstall”, choose Uninstall a program, pop-up “User Account Control”, confirm the program, uninstall it.
But part of the program at Metro applications did not have the corresponding uninstall option, then how to uninstall it? Let’s just find the one we want to remove,right-click it, at the bottom there will be a pop up of uninstall option, we can click to uninstall it then.
