1. Nvcpl.dll is a file in Nvidia's graphics card driver, which is responsible for the adjustment of graphics card parameters together with Nvqtwk.dll. This prompt appears because the file was damaged during the optimization process. If you don't use this function, you can enter "msconfig" in "Run" and press enter, open "System Configuration Utility", search "RUNDLL32.EXE c: \ Windows \ System32 \ nvcpl.dll, nvstartup" in "Start" and just remove the small tick in front of it.

if you still need to use this function, it is recommended to reinstall the corresponding graphics card driver in safe mode.

Tip: DLL files, that is, dynamic link library files, are executable files, which allow programs * * * to enjoy the code and other resources necessary to perform special tasks. Some DLL files are shared by multiple programs * * *. It is a common fault that a certain DLL file is lost or made an error when booting. If the virus infection is eliminated, most of them are caused by incorrect uninstallation of applications, especially drivers and virtual CD-ROM software.

when such a situation occurs, please recall whether the driver or application was uninstalled before this failure occurred. If you can remember, just reinstall this program, and then uninstall it in Add and Remove Programs in Control Panel. Of course, you can also use the uninstall function that comes with the program.

it doesn't matter if you can't remember it. You can write down the name of this DLL file and search in Google. Generally, you can find out what type and application this file belongs to, and then you can install the corresponding program.

if the application mistakenly deletes the DLL files that come with some systems during the uninstallation process, you can copy one from other normal machines with the same system installed, and put it in the prompted directory (generally, C:\Windows\System32\).

in addition, sometimes some DLL files need to be registered with regsvr32 command before they can be used normally. However, I recommend downloading the software of Jinfeng DLL and OCX registration and anti-registration tools from /tools/jfwinreg.exe, and the registration of this DLL file can be completed through its "DLL and OCX registration" function under "File".

Second, the AutoRuns software of Sysinternals is used to solve the problem thoroughly.

It is more professional than Msconfig, optimization master, Kaka assistant, etc., not only to check what everyone knows, but also to check system services, drivers, IE toolbar, BHO, etc.

the only minor shortcoming is that it is written in e, but it does not affect the use.

third, lxcctime.dll, this is probably a virus.
