After your PC boots up to Welcome, you get access denied?

Just follow the steps below.

Start Menu - Run - Enter msconfig Enter.

Put ** in the boot bar insideJust remove the tick in front of the dll.1.Start -- run -- msconfig -- start -- remove the tick from the add-on***dll. Restart the computer, usually this is the case, if it still pops up, then proceed to the second step.

2. Start-Run-regedit Delete the corresponding key in the following location: hkey current user software microsoft windows currentversion run hkey local machine software microsoft windows currentversion run

According to your description, it should be a virus or spyware that has been removed. But it's also possible that you didn't uninstall a piece of software incorrectly.

Start msconfig-start file and remove the checkbox in front of it!

I am!

Start Run regedit Find Input: Delete when found, Find again, delete again, delete again until you can't find it.

It should be that the file is infected with the Trojan, and it will be fine after killing it.

There is only a reinstall system.

I believe that it will not be able to get into safe mode either.

1. After the computer is turned on, keep pressing the "F8" key to enter the advanced boot options, and then select Safe Mode.

2. Log in and enter as an administrator, so that you can get the maximum authority to operate the computer and facilitate future operations. Press "win+r" on the keyboard at the same time to open the running window, and then type "regedit" in the search box, so that you can open the registry window of your computer.

3. In the menu on the left, we will "hkey current user" in turn, then right-click on the item, and then select Permissions in the slide menu.

4. In the pop-up permission setting window, click Add below, and then a window to select a user or group will pop up, you need to enter the object name in the red box in the figure below, that is, the name of the computer account that is logged in, if it has not been modified, it is generally administrator, and then click OK below.

5. After that, return to the group or user name, you can see the option you added, check this option, and then check all the "Full Control" and "Read" in the permission settings below, and finally make sure to exit the window.

When the computer is turned on, it shows that access is denied, and there is a high probability that the system is artificially locked by the application or user, or the hard disk is damaged and write-protected.

The main reason for going directly to the BIOS when booting up is that there is a problem with the settings of the host BIOS. Some computer motherboards are set up to be more user-friendly, so many other functions have been added. When the BIOS is not set up correctly, restarting the computer will automatically enter the BIOS.

Here's how to fix it:

1. Uninstall the conflicting software.

2. Restart the window explorer.

3. Execute the repair script in PowerShell.

4. Execute the repair command in cmd.

5. Repair system services.

6. Restore the system.

Uninstall the conflicting software.

This situation may be caused by conflicting software, if you are sure that this situation occurs after installing a certain software, then you can try to enter the safe mode to uninstall the software: press the window+r, pop up the running window, enter msconfig to bring up the system configuration window, select the boot tab, check the safe boot option, click OK and restart the system.

The system enters the safe mode, uninstall the software that causes the system icon in the taskbar to be unclickable after the recent installation in the safe mode, after uninstalling the software, also follow the above method to bring up the system configuration window, and check off the safe boot option, restart the system again, and see if the problem is solved.

The control panel was also denied?!! Then you can see if "My Documents" or "**Station" can be opened. If it can be opened, click on the address bar to find "My Computer" to see if it can be opened, if it can be opened, it means that there is a virus or Trojan, and it is best to kill it with antivirus software first.

If there is no virus or Trojan horse, there is something wrong with the system, and the system needs to be reinstalled.

Does it prompt a service starting with g that is not logged in? If that's the case, then the only solution for now is to reinstall the system, and after reinstalling the system, it will be fine.

Thank you for adopting.

File Access Denied

It should be that the file is locked, etc., it is recommended to rename your file under C: Windows in safe mode cmd, for example:

c:\>cd windows

c:\windows>ren 。

Correct. It is recommended to check and kill the Trojan horse and repair the system.

:** After installation, first upgrade to the new version of Sixiao, then exit normal mode and reboot press F8 to enter safe mode. Open the software, click "System Scan", select all the scan results, and then click the "Perform Cleanup" button, if the software prompts you whether to "backup", select "Yes" (the backup is to prevent the occurrence of cleaning errors, if the system does not occur abnormal after cleaning, delete the backup), follow the prompts to operate (the software can also be killed in normal mode).

Boot press F8 to immobilize to the advanced option appears in the let go, select "the most recent correct configuration" Enter to repair.

After booting up, press F8 to enter safe mode, and then exit, select Restart or Shut Down to boot on, you can enter normal mode (repair registry).

If the fault persists, please use the system restore that comes with the system to restore the system to repair it when you did not have this fault (or use the restore software to restore the system).

If the fault persists, use the system disk to repair it, open the command prompt and enter sfc scannow (there is a space between sfc and ), insert the original system disk to repair the system, and the system will automatically compare the repaired ones.

If the fault persists, set the optical drive in the BIOS as the first boot device, insert it into the original system installation disk, press the R button, and select "Repair Installation".

If the fault persists, we recommend that you reinstall the operating system.

1) Press F8 immediately after booting or not turning on the phone first press F8 not to move to the advanced option to let go of the hand, use the up and down keys to select the safe mode enter, enter the safe mode and use the software to kill the Trojan, uninstall all the things installed before the accident, including the game, restore the system or reinstall the system (if you can enter the safe mode, it means that you have installed something inappropriate, and uninstall all the inappropriate Dongzai Sun Xi before the accident, if not, restore the system or reinstall, if you can enter the normal mode, In normal mode, it is also done as above).

2) If the above methods can't solve the problem, first soft and then hard, reinstall the operating system, don't install software, patches, drivers, etc., and see if there are still problems with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

3) If it is caused by hardware problems, it is recommended to overhaul it. Get out.

4) If you have any questions, please ask me.

F8 Safe Mode is entered once.
