First, the right-click menu of Explorer 1 Delete redundant items in the right-click menu. As we all know, when installing many softwares, you must first extract your installation files into a temporary directory (usually the temp directory under the Windows folder), such as tools such as WinZip, and then install them. If the software design is negligent or there is something wrong with the system, these temporary files will not be "temporary" and become a pile of garbage on the hard disk after installation, and often appear in the form of *. Tmp face; In the process of software running, there are usually some temporary exchange files, such as backup files such as *. Old and *. Bak generated when some programs work, backup files generated when antivirus software or system software checks the hard disk, etc. Some folders will be left after the software is uninstalled. Dll file. Hlp files on the hard disk, registry key values, and all kinds of unknown gadgets will become genuine garbage. In fact, after we uninstall an application normally, we will leave some unnecessary items in the right-click menu, which also need to be deleted. These legacy items are generally stored in "HKEY _ Class _ Root \ * \ Shellex \ Context Menu Handler"; If an item is valid only for folders, it will be stored in HKEY _ Class _ Root \ Directory \ Shell and HKEY _ Class _ Root \ Directory \ Shell \ Context Menu Handler, and sometimes in HKEY _ Class _ Root \ Folder \ Shell and HKEY _ Class _ Root \ Folder. Find it and delete it. In addition, the search function of the registry can also be used to remove the legacy files after uninstallation, search the software-related key values in the registry, find and delete, and there may be more than one. At this point, you can use the F3 shortcut key to continue searching until all items are deleted. (Tip: Before deleting any registry, please export the items to be deleted in the Registry Editor. )

2. Delete the option in the "New" submenu. Select "New" from the menu that pops up when you click the right mouse button, and the newly created files corresponding to the installed applications in the system will be displayed. With more and more applications in the system, the content in the "New" submenu will also increase. However, in daily use of computers, users do not need to create so many types of files. In fact, we can completely delete the options in the "New" menu by modifying the registry, and the operation is not complicated. Just start the Registry Editor and delete the "ShellNew" item under [HKEY _ Class _ Root]. * * *] (".* * *" is the file extension of the item to be deleted), then quit Registry Editor and restart the computer. Let's take deleting the "WinRAR compressed file" item in the "New" submenu as an example; First, find [HKEY local machine software class]. Rar], delete the "ShellNew" item under it, return to the desktop, press F5 to refresh, then right-click in the blank space of the desktop and select "New". At this time, you will find that the original "WinRAR compressed file" has disappeared. 3. Delete the useless items in the "Open Mode" submenu. Right-click a file, and there may be some programs we don't need in the "Open Mode" submenu of the right-click menu. There are three programs in Open Mode. TXT "file, but some are not used at all. At this time, just go to [HKEY _ Current _ User \ Software \ Microsoft \ Windows \ in the registry. Find the corresponding extension items in currentversion \ explorer \ fileexts] and [HKEY _ class _ root \ system file association], and then delete the unnecessary key values or items in the "OpenWithList" subitem. Let's take deleting useless items in the "Open Method" submenu of the right-click menu of a text file as an example. Go to [HKEY Current User \ Software \ Microsoft \ Windows \ Current Version \ Explorer \ File Extension \. Txt \ openwithlist] delete the corresponding key value in the right pane, and then go to [HKEY _ class _ root \ system file association \ text \ openwithlist] to delete the corresponding subitem.

Second, let IE go into battle lightly. With the continuous development of network technology, communication through the network has become a part of many people's daily life. However, the disharmony in IE is always heartbreaking. The window title and default home page have been changed beyond recognition; Right-click menu, toolbar, toolbar is forced to add all kinds of messy content and so on. In fact, these situations can be solved by 372 1 Internet assistant. If it is not installed in your system, you can open assistant.372 1.com in your browser, download and install the Internet Assistant in your system. After installation, it is recommended to restart the system before proceeding to the next step. 1, clear IE right-click menu In the webpage window opened by the browser, when you click the right mouse button, a shortcut menu will pop up, from which we can quickly download files, save pictures and many other operations. But now many programs will add related items to IE right-click menu as long as they are installed in the system. In the long run, IE right-click menu will not only become bloated, but also make the pop-up time of right-click menu longer and longer, which will affect the operation of the system. So it is necessary to clean up unnecessary right-click menu items. Start IE browser first, and then click "Internet Assistant → Repair IE→ Restore IE Appearance" at the bottom of the address bar to open the window. To clean the IE right-click menu, we only need to select the "Clean IE right-click menu" tab in the window to open a new window, and the list in the middle shows all the items in the current IE right-click menu. If you want to clear any item, just select it with the mouse and click the Clear Now button. 2.IE toolbar buttons are cleaned in a similar way. Click "Clear IE toolbar button" to enter the function page: the list in the middle shows the buttons that can be cleared on IE toolbar. Simply click the check box in front of each item, and then click Clear Now to delete the selected toolbar button. Reopen an IE window, and you can see that the deleted toolbar button has disappeared. 3, clean up IE toolbar Because of the flexibility of IE, its toolbar can also be added at will. In the case that many toolbars want to be placed on IE, IE becomes more and more crowded. In addition, if more than three toolbars are loaded, the startup speed of IE will decrease. This is because when IE starts, it will initialize the toolbar to be loaded and complete some settings. We won't feel anything when there are only 1 and 2 toolbars. And more than three, the speed will be significantly reduced. In addition, if the contents of the toolbar need to be downloaded from the internet immediately, then this delay is more obvious. Therefore, it is recommended that you only load 2 toolbars at most. Of course, IE also provides the function of not loading toolbars. Click "View → Toolbar" to see the toolbars installed in IE, among which "Standard Button" and "Address Bar" are the most basic and should not be deleted. Others, such as "links", are of little use and do not need to be loaded. The method is to click this item, the "check" mark in front disappears, and the toolbar represented by this item is no longer displayed in IE. But obviously, this operation is troublesome, because IE needs to refresh every time it removes a toolbar.

Third, delete invalid shortcuts. As we all know, whether it's Windows 9x/Me or Windows XP with SP 1 patch, after a long time, there will be more and more junk files and junk information in the system. In Windows, there is another kind of garbage that is not well known, that is, invalid shortcuts. For example, the folder where a software (or file) is located has been modified, but its shortcut still points to the original location, or the software has been uninstalled or the file has been deleted, but the corresponding shortcut is still left in "Start → Program", "Start → Document" and "C:\Progeam Files". At this time of Windows, you can use the Windows optimizer to clean them up, or use the free software OrphansRemover (download address: http://www.digiarch.org/download/Orphans Remover. zip) to find and clean them up. Run OrphansRemover after downloading and installing, and select the folder to scan and invalid shortcuts such as mobile storage and CD. At the top of the software window, under "Select the folder of orphan shortcuts:" and "Include shortcuts with broken links:". The User Defined Search Folder text box allows you to specify a folder. Finally, click the "Start Scanning" button at the bottom of the window to start scanning, and then click the "Delete Orphan" button to delete the invalid shortcut. In addition, OrphansRemover also supports command line parameters, such as "d: \ program files \ Orphans Remover \ orphansremover.exe recent start menu -silent" to clear invalid shortcuts in documents and start menus, where "recent" is the document and "start menu" is the start menu. "For other parameters, please refer to the relevant instructions in the manual.html file of Orphans Remover installation folder.

Fourth, clean up the useless font 1 and delete the useless font. In the process of document processing or art design, in order to meet aesthetic or other requirements, we may need to install and use some special fonts that are not available in the system. Over time, I'm afraid I don't even know how many fonts are installed in the system. In fact, when there are more than 500 fonts, there will be problems such as fonts disappearing from the list of applied fonts, and Windows startup speed dropping sharply. Obviously, too many fonts not only occupy more system resources, but also affect the overall performance of Windows. In order to improve system performance, it is recommended that you delete unused or infrequently used fonts. If you want to delete useless or uncommon fonts, you should know which fonts can't be deleted. First of all, Song Ti can't be deleted, it is the default Chinese font; Screen font file (extension. Fon) can't be deleted at will, otherwise the text in some dialog boxes will become garbled, and even Windows 98/Me can't be started. ".SYS" is a system font, which is used for system prompt information and icon description text. Deleting it may cause system crash; There are still some symbols, such as marlett, winding and other fonts, which cannot be deleted at will. And don't delete fonts with these words: Arial, Courier, MS Serif, Tahoma, Verdana, Comic Sans, MS Sans Serif, Symbol, Time New Roman, Impact, Lucida Console, Marlett, Modem, Samarlfonts, Webdings, Windings, Roman, MS-DOS CP437, script, SIMHEI, SimSun & ampNSimSun, Palatino, Linotype, Microsoft, Microsoft. In addition, there are many similar fonts installed in Windows, which are unnecessary and almost impossible to use in many cases, so you can find out similar fonts and keep a few of them for other purposes. In order to avoid system failure caused by deleting FONTS by mistake, it is suggested to move fonts out of the "fonts" folder and save them in another directory, such as "D:\fontsback". At the same time, create a shortcut for the file and put it on the start menu or quick launch bar. When using these fonts, just open the folder and double-click a font to display it in the preview window. As soon as the preview window opens, fonts are loaded into memory and can be seen in the font menu of any application. Users can load a variety of fonts in this way, and then close the preview window after using them.
