Windows system security tips

  
The intelligence of the computer has brought us great convenience, but also buried the fuse of leaking. Once someone else uses or invades your computer, a lot of information will be found through simple searching. Such as received and sent messages that you have deleted, visited Internet sites, data entered in web forms, passwords and personal information, and even words used in documents. Therefore, it is especially important to master some secret techniques to protect privacy from intrusion. Here are some tips to help you create a safer operating environment. Turn off the display of recently used file features Even if an intruder can't directly view the contents of a document you've processed, you can see how you work by looking at the files you've recently used in the File menu in Word or Excel. This temporary list even lists the files that have been deleted by you recently, so it's best to turn it off. In Word or Excel, select the "Tools" menu, then select the "Options" menu item, then go to the "General" tab, in the "General Options" uncheck the check mark in front of the check box in front of "List the most recently used files" (Figure 1). Turning off the recycle bin In the default installation mode, the files we deleted are not actually deleted, but are also stored in the recycle bin. Therefore, in order to completely delete files, you should remove the files from the recycle bin that you think are definitely not used. Of course, we can also empty the recycle bin at any time, but a better way is to turn off the recycle function of the recycle bin. To completely delete a file at once, right-click on the recycle bin icon, select "Properties", then go to the "Global" tab, select "All drives use the same settings", and do not move the files in the "Delete" The Recycle Bin, but completely remove the checkbox is marked with a checkmark (Figure 2). Temporary files are cleared at any time Word and other applications usually intelligently temporarily save your work results to prevent accidental damage. Even if you don't save the file you are working on, many programs save the text that you have deleted, moved, and copied. Temporary files stored in the \\Windows\\Temp folder by various applications should be deleted periodically to remove these scattered text. Refusal to record URLs IE browser will wisely record every URL you enter in the browser. You may wish to verify: enter a URL in the address window below the toolbar, and the browser will record the address in the drop-down menu. Until there are other items to replace. You can access the website in the following way, but the URL used is not recorded: you can press Ctrl+O in the browser, and then enter the URL address in the dialog box (Figure 3). Clearing cached information in a timely manner IE saves the webpages you have visited recently in the hard drive cache. When you visit these webpages again, the cached information speeds up the access of the webpages, but it also reveals your secrets to the snoopers. To clear the information in the cache, select "Internet Options" from the Tools menu in IE, then go to the "General" tab and click the "Delete Files" button. You can also set the browser so that it doesn't use the cache at all, which of course slows down page access. In IE, select "Tools" "Internet Options" "General", click the "Settings" button to the right of "Internet Temporary Files", and then move the slider under "Used Disk Space" to the far left end (as shown in Figure 4). Important File Password Protection Password protection for important files, which is easy to implement in Word and Excel, select "File" "Save As", then select "General Options" in "Tools", "Open Permission Password" and Enter the password in "Modify Permission Password" (Figure 5). It is best not to use common words and dates as passwords. You can mix letters, numbers and punctuation marks so that the password is difficult to decipher, but you have to remember the password yourself. In order to avoid causing trouble for yourself. Of course, every time you open and modify a document, you must enter your password. Although it is a bit cumbersome, it is safe. Clearing History IE lists all the objects that have been visited, including the pages that have been viewed, the queries that have been made, and the data that was entered. IE saves the page visit history in a folder divided by week or by URL. We can delete individual addresses (URLs) individually, but the fastest way is to delete the entire folder. To clear all history, select Internet Options from the Tools menu, then select the General tab and click the Clear History button. If you are bothered to do this every time, just set the "number of days to save the page in the history" to "0", you can do it once and for all (Figure 6).
