Disposal of the method and procedure of the "Show all files and folders" option cannot be changed

1. First modify the system file hiding function, enter the "Folder Options" window, click "Tools" in the menu bar, and select "Folder Options" in the pop-up menu.

2. Click "View" in the folder options window, find "Show all files and folders" and "Do not show hidden files and folders", and select "Do not show hidden files and folders".

3. Change to "Show all files and folders" item, and press Apply and OK.

4. Go to the C drive to find those hidden files, but the result is still not displayed. Why? Obviously, the hidden properties have been changed, and then go back to the "Folder Options" to see, and it turns out that the changed settings have returned to the previous state, and after repeated settings, they still can't be changed.

5. Why is this happening? Could it be the registry to blame? Try opening the registry, and in the Run window, enter the regedit command.

6. After entering the registry, find the registry about the hidden folder - [Hkey Local Machine Software Microsoft Windows CurrentVersion Explorer Advanced Folder Hidden Showall] This path finds the checkedvalue entry on the right and double-clicks.

7. In the dword value window, change the value of 0 under "Numeric Data" to a value of 1, and press "OK". After this change, the value of prompt 1 is allowed to modify the hidden property, and the value of 0 is not allowed to modify the hidden property.

Modify the checkedvalue"=dword: 00000001 note that the value of checkedvalue is dword type, there may be some viruses or Trojans to change it to a character type, but the name of the key is still checkedvalue, the solution is to delete the original value, and then the registry's -new-> dword value, named checkedvalue, the value is 1; Otherwise, your key to change that character will not work!

You can see the importance of the homepage!

Personally, I think it's the fastest way to delete the IE shortcut and then resend a shortcut to the desktop from the IE folder in the C drive.

I usually open the perfect uninstall monitoring installation process before installing things now, and I feel a lot better.

The above is purely personal experience, and we hope to forgive me for any shortcomings.

Remove the hidden protected system files, click Show all files and folders, and click "Apply to all folders" (L)."Press OK. Generally this is fine, if there is no change, but the code can be hit by the virus, and scan it with the security software of the mold pick 360 Kingsoft.

Ways to show hidden files.

Open Notepad and copy the following:

windows registry editor version[hkey_local_machine\software\microsoft\windows\currentversion\explorer\advanced\folder\hidden\showall]

checkedvalue"=dword:00000001 Save filename:"Show hidden files."

reg", (make sure to remove the "Hide Extensions for Known File Types" in the Folder Options), double-click to run the file, and then go back to the Folder Options to set Show Hidden Files.

Sometimes after a virus in the system (e.g. and lsass (falling snow virus)), the antivirus software cannot kill the virus, or there is no antivirus software. This is where manual antivirus is required. At this time, it is often necessary to delete the virus file, which always hides itself in order to protect itself.

Set the file properties to hidden, and we can modify the hidden files through the general virus menu: Tools - Folder Options - View - Show hidden files. However, many viruses make this operation ineffective by modifying the registry, and we still can't see the hidden files, so the following operation is to teach us how to make the hidden files reveal by modifying the registry.

The first thing to do is to show the hidden system files.

Run regedit

hkey_local_machine | software |microsoft | windows | currentversion | explorer | advanced | folder | hidden |showall, change the checkedvalue key to 1

But it may still not work, the hidden file is still not displayed, this is because the virus deleted the original valid dword value checkedvalue after modifying the registration expression to the purpose of the hidden file, created a new invalid string value checkedvalue, and changed the key value to 0!

Method: Delete this checkedvalue key, right-click to create a new DWORD value, name it checkedvalue, and then modify its key value to 1, so that you can choose "Show all hidden files" and "Show system files".

I've also come across something like this, and my workaround is simple:

In the BIOS settings, select: Load Optimized Defaults and you're good to go! Usually one of the two BIOS is to select "Load Optimized Defaults" with the up, down, left, and right keys, and then save and exit, and the other is the way to do it on the BIOS

Press the F7 key on the top row of the keyboard, then save and exit! Give it a try, when there are some inexplicable problems in the computer, you can use this method to set the BIOS to the best mode to solve the problem!

Finally, a wordy sentence: to enter the BIOS is to keep pressing the del button after booting!

It should be that you have lost the administrative privileges of the registry, and the above import operation of the registry may not be successful. Because it's possible that a piece of malware has locked the registry, you'll need to find out the bad software before you can change it. It is recommended to use safe360 to check and kill to see if there is any malware.

Generally, reinstalling the system can solve the problem, which is more straightforward than other solutions. The last time I was in such a situation, it seemed that it was no problem to reinstall the system. Why don't you try changing this attribute on other users?

You must be plugged in the portable hard drive when 360 antivirus prompts you to open it safely, you click on the safe open, right? Don't click on the 360 Security Guard prompt to turn on safely. Just open it the normal way.

It's okay with this virus, it's a problem caused by 360 antivirus safe opening!

Create a new notepad and copy and paste the following content into the notepad:

windows registry editor version[hkey_local_machine\software\microsoft\windows\currentversion\explorer\advanced\folder\hidden\showall]

regpath"="software\\microsoft\\windows\\currentversion\\explorer\\advanced"

text"=",-30500"

type"="radio"

checkedvalue"=dword:00000001"valuename"="hidden"

defaultvalue"=dword:00000002"hkeyroot"=dword:80000001"helpid"=""

File -- Save As -- Select "All Files" from the Save Type drop-down menu below.

Keep it and double-click to run, add it to the registry OK.

It is caused by a virus Trojan replacing some files.

Don't restart your computer again!! Don't start any more programs and kill the virus right away!!

Poisoned reinstall the system.

1. Right-click on the taskbar and select "Start Task Manager".

2. Select "Resource Monitor" under the "Performance" tab

3. Enter the name of the file or folder in the "Associated Handle" field under the "CPU" tab. For example, the folder to be deleted is called "Shark".

Okay, I see.

You put the software in that folder, and as soon as you boot it, the software in that folder starts up or runs in the background with the boot, so when you change the name of this folder, it will prompt you to cut the folder to be opened or called in another program.

If you go straight to the folder name, you probably won't be able to use a lot of the software you have installed, because the files you installed are registered in the registry when you install them, and they use the current folder name. Don't change it.

Please run msconfig, disable all boot items, and then restart, change, try.

Obviously, you close all the documents and folders that are currently open. Then change the name to OK
