我敢肯定，很多人都听说过可以消除预装在我们计算机上的所有臃肿的程序。许多博客和专家都推荐了PC Decrapifier、SlimComputer或Decrap等工具。但是……它们真的有用吗？它们真的能有效地从您的计算机中删除所有臃肿(Are)软件和垃圾软件吗？(bloatware and crapware)从此分析中了解答案：
Bloatware , Crapware ,不需要的软件(Software)
这个问题有很多名字。不管你怎么称呼它，这都是一种可悲而普遍的做法。每次您购买新计算机（台式机或笔记本电脑(desktop or laptop)）时，其制造商都会将其与一些预装软件一起出售，其中大部分您都不需要。
该预装软件可能会提示您为其购买许可证或安装其他工具，从而惹恼您。有时，该软件提供的有用功能很少，并且会对系统性能产生负面影响。为了更好地了解性能是如何受到影响的，我推荐这个古老但仍然很有见地的分析：The Crapware Con。
现在......你如何摆脱臃肿软件，垃圾软件 - 无论你想怎么称呼它？许多网站和博客推销的一种解决方案是使用PC Decrapifier、SlimComputer或Decrap等软件。
至少在理论上，这些程序会扫描您的计算机以查找促销程序、工具栏、广告链接或试用优惠(advertising or trial offers)。然后，它们将帮助您以或多或少的自动化方式删除它们。
PC Decrapifier - 它是如何工作的？
PC Decrapifier是一款免费工具，您可以直接下载并运行，无需任何安装。它首先根据预定义的已知垃圾软件列表分析您的计算机。然后，它会显示它认为是垃圾软件的所有软件，并将其分为三个不同的列表：
-
推荐：(Recommended:)此列表中显示的程序已被许多用户删除。
-
可疑：(Questionable:)这些程序被一些PC Decrapifier用户删除。他们可能并不都是垃圾软件。
-
Everything Else：是(Everything Else:)PC Decrapifier没有足够信息的程序和应用程序。该工具不知道这些是否是垃圾软件。
您可以浏览这些列表并选择要自动卸载的垃圾软件。做出选择后，按PC Decrapifier窗口底部的删除选定按钮。(Remove Selected)
在下一个屏幕上，您将看到将从计算机中删除的所有内容的完整列表。在窗口底部，您还可以选择PC Decrapifier是否会在继续卸载过程之前自动创建系统还原点。这是一个很好的做法，我们建议您这样做。
SlimComputer – 它是如何工作的？
SlimComputer至少在概念上与PC Decrapifier非常相似。SlimComputer是一个工具，您必须下载并安装才能使用它。
SlimComputer会根据已知的膨胀软件列表扫描您的计算机。如果识别出已知项目，您可以自动删除它们。如果没有，您可以转到卸载(Uninstaller)程序部分并手动删除您不需要的程序。
Decrap——它是如何工作的？
Decrap是另一个将自己宣传为垃圾软件删除工具的程序。
与PC Decrapifier(PC Decrapifier)和SlimComputer类似，它首先分析您的计算机是否存在已知的膨胀软件。
完成后，Decrap 会将(Decrap)所有所谓的垃圾软件显示到单独的列表中：自动启动软件、桌面项目、驱动程序和其他可能重要的软件、开始菜单项、第三方软件(Automatically Starting Software, Desktop Items, Drivers and other probably important software, Start Menu Items, Third Party Software)和Windows 相关软件(Windows Related Software)。除了驱动程序和其他可能重要的软件(Drivers and other probably important software)和Windows 相关软件(Windows Related Software)这两个例外，所有其他列表都会自动选择删除。
但是，请注意不要按Next。我们发现Decrap(Decrap)有一个非常不幸的问题：它会自动选择删除几乎所有安装在您计算机上的东西。我们真正的意思是一切：如果您不注意并取消选择它，即使Internet Explorer也会被卸载。(Internet Explorer)
如果您想使用Decrap，我们强烈建议您手动选择将从您的计算机中删除的程序。
我们用于测试的Bloatware / Crapware
为了测试这三个程序的有效性，我们安装了以下与某些型号的计算机捆绑在一起的软件：Cyber Link PowerDVD(CyberLink PowerDVD)、Adobe Reader、Magic Desktop、WeatherBug、HP MediaSmart Video DVD Menu Pack、HP Advisor、Asus FancyStart、Picasa 3.9、Norton Security Scan、AVG Security Toolbar、Ask Toolbar 和 Ask Toolbar Updater(Ask Toolbar and Ask Toolbar Updater)。
虽然其中一些程序（例如Adobe Reader）可能对某些用户有用，但其他人会认为它们是不必要的臃肿。
安装上述软件后，我们运行每个工具以了解它们将哪些项目识别为英国媒体报道软件以及是否将其删除。
PC Decrapifier、SlimComputer 和 Decrap 工作(SlimComputer and Decrap Work)吗？
简单而令人惊讶的答案是：“不！它们不起作用！”。它们与安装在您新购买的计算机上的大多数英国媒体报道软件一样有用。
我们了解到，所有这些程序都不擅长识别垃圾软件：
-
PC Decrapifier仅识别出三个项目——Ask Toolbar(Ask Toolbar)、 WeatherBug 和HP MediaSmart Video的DVD 菜单包(WeatherBug and DVD Menu Pack)。
-
SlimComputer没有发现任何物品是垃圾软件。
-
Decrap将所有内容都认定为过时软件，包括Internet Explorer等(Internet Explorer)Windows程序。
我们可以使用这些工具的唯一方法是手动启动我们不需要的程序的设置并手动卸载它们。您可以从Windows执行此操作，无需安装任何其他应用程序，使用我们在本教程中描述的步骤：添加或删除程序消失了(Did Add or Remove Programs Disappear)吗？在哪里可以找到它？
您可能会说我们使用了一个简短的/ crapware程序列表。但这不是问题。
真正的问题是这些程序要么使用被认为是英国媒体报道软件的预定义项目列表，要么不使用任何项目。例如，PC Decrapifier在其列表中仅包含 50 个应用程序，其中Top Applications Removed。我们找不到SlimComputer的类似列表，但我们确定它使用了一个。至于Decrap，几乎所有安装在计算机上的东西都被认为是英国媒体报道软件这一事实足以证明它不使用任何列表。
如果此类列表没有定期更新，并且它们不包括所有大型 PC 制造商安装的英国媒体报道软件，那么它们就不会很好地工作。
那么...您如何删除垃圾软件？
在此体验之后，我们不建议使用承诺删除计算机上安装的垃圾的工具。除非投入大量精力来维护这些产品并保持最新的垃圾软件列表，否则它们就是行不通的。
删除不需要的软件的唯一方法是从Windows手动删除，或者使用更高级的软件卸载程序，以消除他们留下的东西。您可以在这篇文章中找到关于好的工具的建议：软件卸载程序(Software Uninstallers)综述- 回顾IObit与Ashampoo 与(Ashampoo vs) Revo。
How To Remove Crapware With PC Decrapifier, SlimComputer Or Decrap
I'm sure mаny have hеard about programs that promise to elіminate all the bloat that comes preinstalled on our computerѕ. Τools like PC Decrapifier, SlimComputer or Decrap have been recommended by many blogs and experts. But... do they really work? Are they really effective in removing all the bloatware and crapware from your computer? Learn the answer from this analysis:
Bloatware, Crapware, Software You Don't Need
This problem has been given many names. No matter what you call it, it is a sad and common practice. Each time you buy a new computer (desktop or laptop), its maker will sell it with some pre-installed software, most of which you won't need.
This pre-installed software may annoy you with prompts to buy a license for it or install additional tools. Sometimes this software provides little in terms of useful features and has a negative impact on the performance of your system. To get a good picture of how performance can be affected, I recommend this old and still insightful analysis: The Crapware Con.
Now... how do you get rid of bloatware, crapware - whatever you want to call it? One solution marketed by many websites and blogs is to use software such as PC Decrapifier, SlimComputer or Decrap.
At least in theory, these programs will scan your computer for promotional programs, toolbars, links to advertising or trial offers. Then, they will help you remove them in a more or less automated manner.
PC Decrapifier - How Does It Work?
PC Decrapifier is a free tool that you can download and run directly, without any installation required. It starts by analyzing your computer against a predefined list of known crapware. Then, it displays all the software it thinks is crapware and classifies into three different lists:
-
Recommended: the programs displayed in this list are removed by many users.
-
Questionable: these programs are removed by some PC Decrapifier users. They might not be all crapware.
-
Everything Else: are programs and applications about which PC Decrapifier doesn't have enough information. The tool doesn't know if these are crapware or not.
You can browse these lists and select the crapware you want automatically uninstalled. When you've made your selection, press the Remove Selected button on the bottom of the PC Decrapifier window.
On the next screen, you'll see the complete list of everything that will be removed from your computer. On the bottom of the window, you can also choose whether PC Decrapifier will automatically create a system restore point before proceeding with the uninstall process. This is a good practice and we recommend that you do so.
SlimComputer – How Does It Work?
SlimComputer, at least in concept, is very similar to PC Decrapifier. SlimComputer is a tool that you must download and install in order to be able to use it.
SlimComputer scans your computer against a list of known bloatware. If known items are identified, you can remove them automatically. If not, you can go to the Uninstaller section and manually remove the programs you don't need.
Decrap – How Does It Work?
Decrap is another program that advertises itself as a crapware removal tool.
Similarly to PC Decrapifier and SlimComputer, it starts by analyzing your computer for known bloatware.
Once done, Decrap displays all the so called crapware into separate lists: Automatically Starting Software, Desktop Items, Drivers and other probably important software, Start Menu Items, Third Party Software and Windows Related Software. With two exceptions, Drivers and other probably important software and Windows Related Software, all the other lists are automatically selected for removal.
However, beware of pressing Next. We found a very unfortunate problem with Decrap: it automatically selects for removal almost everything installed on your computer. By that we really mean everything: even Internet Explorer is uninstalled if you don't pay attention and deselect it.
If you want to use Decrap, we highly recommend that you to manually choose which programs will be removed from your computer.
The Bloatware / Crapware We Used For Testing
In order to test the effectiveness of these three programs, we installed the following software that is bundled with certain models of computers: CyberLink PowerDVD, Adobe Reader, Magic Desktop, WeatherBug, DVD Menu Pack for HP MediaSmart Video, HP Advisor, Asus FancyStart, Picasa 3.9, Norton Security Scan, AVG Security Toolbar, Ask Toolbar and Ask Toolbar Updater.
While some of these programs (e.g. Adobe Reader) can be useful to some users, others will consider them unnecessary bloat.
After installing the software mentioned above, we ran each tool to learn what items they identify as bloatware and if they remove them.
Do PC Decrapifier, SlimComputer and Decrap Work?
The simple and very surprising answer is: "No! They don't work!". They are as useful as most of the bloatware installed on your newly purchased computer.
We learned that all these programs are not that good at identifying crapware:
-
PC Decrapifier identified only three items - Ask Toolbar, WeatherBug and DVD Menu Pack for HP MediaSmart Video.
-
SlimComputer identified no items as being crapware.
-
Decrap identified everything as being bloatware, including Windows programs like Internet Explorer.
The only way we could use these tools was to manually launch the setup of the programs we did not want and uninstall them manually. And you can do that from Windows, without installing any additional applications, using the steps we described in this tutorial: Did Add or Remove Programs Disappear? Where to Find It?.
You might say that we used a short list of bloatware / crapware programs. But that's not the issue.
The real issue is that these programs either use a predefined list of items that are considered bloatware, or they don't use any. For example, PC Decrapifier includes only 50 applications on its list with Top Applications Removed. We could not find a similar list for SlimComputer, but we're sure it uses one. As for Decrap, the fact that almost everything installed on a computer is considered bloatware is enough to prove that it uses no list whatsoever.
If such lists are not updated regularly and they don't include bloatware installed by all the big PC makers, then they won't work very well.
So... How Do You Remove Crapware?
After this experience, we do not recommend using tools that promise to remove the crap that's installed on your computer. They just won't work, unless a lot of effort is invested into maintaining these products and keeping very up-to-date crapware lists.
The only way to remove the software you don't need is to do it manually from Windows, or to use more advanced software uninstallers, to eliminate also the things that they leave behind.
