当您打开Windows PC 时，许多隐藏的系统服务和进程会开始运行。这些过程决定了Windows在屏幕上的显示方式、设备连接到本地网络的方式、访问连接设备的方式、登录Windows等。没有它们，您的 PC 将无法工作。
您将在Windows 10中看到的更不寻常的进程之一是 lockapp.exe 进程。这不仅仅是任何旧的可执行文件(executable file)，因为 lockapp.exe 负责绘制锁定屏幕的一部分（您将在登录之前看到的屏幕）。如果您想了解有关此系统流程的更多信息，以下是您需要了解的内容。
什么是 lockapp.exe，它安全吗？(What Is lockapp.exe and Is It Safe?)
首次加载Windows 10电脑时，您不会立即看到登录提示 - 您会看到背景、时钟和日期，以及您添加的任何其他状态项目，包括网络连接和电池电量。这是锁定屏幕，它只不过是您 PC 的迷人闪屏。
lockapp.exe进程是生成和控制此屏幕的原因。(lockapp.exe)它并没有做太多其他事情，也不应该对您的系统造成太大的麻烦。虽然一些用户不时报告CPU和RAM使用率过高，但这是非常不寻常的情况，因为 lockapp.exe 在正常使用期间不应使用太多。(RAM)
当您登录时，lockapp.exe 应该处于休眠或隐藏状态，等待您锁定 PC 或再次退出。作为一个正版系统进程，lockapp.exe 是完全安全的，但在极少数情况下恶意软件以相同的文件名在您的系统上伪装，您可以使用以下步骤检查它是否是正版。
lockapp.exe 会导致高 CPU、RAM 或其他高系统资源使用率吗？(Can lockapp.exe Cause High CPU, RAM or Other High System Resource Usage?)
在正常使用中，lockapp.exe 进程应该使用非常有限的系统资源——我们在这里和那里谈论几兆字节的RAM 。CPU使用率也可能在登录过程中受到限制，并且在您登录后应该为零。
这是因为 lockapp.exe 要么在您登录后处于“暂停”模式（意味着它没有主动运行），要么完全停止并隐藏。您可以使用任务管理器自行检查，但对于所有(Task Manager)Windows 10用户来说应该是相同的。
解决 Windows 10 上的 lockapp.exe 问题(Troubleshooting lockapp.exe Issues on Windows 10)
但是，网上有报道说 lockapp.exe 会导致一些CPU和RAM问题。这是不寻常的，可能是由错误或损坏的系统文件引起的。如果您怀疑您的系统文件已损坏，您可以运行系统文件检查器 (SFC) 工具(run the System File Checker (SFC) tool)。
- 为此，请右键单击开始(Start)菜单并选择Windows PowerShell (Admin)选项。
- 在新的PowerShell窗口中，键入sfc /scannow并选择键盘上的Enter键。
SFC工具将需要一些时间来完成对您的系统的扫描。如果它检测到任何损坏的文件，它将使用系统文件的保留快照来恢复它们。完成此操作后，您可能需要重新启动 PC。
如果SFC未检测到损坏的文件，但您的系统已过时，您可能会错过重要的错误修复。要解决此问题，您需要检查是否有任何更新。
- 您可以在Windows 设置(Windows Settings)中检查更新。右键单击开始(Start)菜单并选择设置(Settings)以打开此菜单。
- 在Windows 设置(Windows Settings )菜单中，您需要选择更新和安全(Update & Security )> Windows 更新( Windows Update)来查看您的更新选项。如果有任何可用的更新，请选择适当的选项来下载并安装它们。否则，选择检查更新(Check for Updates )以开始搜索。
如果有任何可用的系统更新，请按照屏幕上的说明下载并安装它们，然后重新启动 PC 以完全应用它们。虽然这不能保证解决锁定屏幕覆盖的任何问题，但它可以确保您安装了最新的可用错误修复。
如何在 Windows 10 上禁用 lockapp.exe(How to Disable lockapp.exe on Windows 10)
虽然 lockapp.exe 是一个系统进程，但它不如dwm.exe和其他关键进程重要。禁用它将直接带您进入登录提示。
- 要禁用 lockapp.exe 进程，您需要创建一个新的Windows 注册表(Windows Registry)项。为此，请右键单击“开始(Start)”菜单并选择“运行”(Run)。
- 在“运行”(Run)对话框中，键入regedit，然后选择“确定(OK)” 。
- 使用注册表编辑器，找到HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization 键。如果它不存在，请通过右键单击Windows键，然后选择New > Key来创建它。找到（或创建）此键后，右键单击右侧的白色窗格，从列表中选择新建(New )> DWORD（32 位）值(DWORD (32-bit) value )。将新值命名为NoLockScreen。
- 双击(Double-click)新值，然后在数值数据(Value data)框中键入1 。选择确定(OK)保存。
保存后，锁定屏幕覆盖将被禁用，并且 lockapp.exe 不会激活。下次您锁定 PC 或登录时，您将直接看到登录提示 - 覆盖不会出现。
配置锁定屏幕(Configuring the Lock Screen)
锁定屏幕是可配置的，允许您添加某些通知，例如收件箱中未读电子邮件的数量。要进行配置，您需要使用Windows Settings。
- 右键单击(Right-click)开始(Start)菜单并选择设置(Settings)开始。
- 在设置(Settings)菜单中，选择个性化(Personalization)>锁定屏幕。( Lock screen. )从这里，您可以更改锁屏背景并添加其他应用程序以查看其“快速状态”通知。这可能包括您的日历、收件箱、新闻应用等。
如何检查lockapp.exe是否为正版(How to Check Whether lockapp.exe Is Genuine)
(Windows)与早期的Windows版本相比， (Windows)Windows 10 更擅长保护用户免受伪装成正版系统进程的恶意软件的侵害，但此类恶意软件也并非不可能感染您的 PC。如果您想检查 lockapp.exe 是否为正版且可以安全运行，您可以使用任务管理器(Task Manager)进行。
- 要启动任务管理器(Task Manager)，请右键单击开始(Start)菜单并选择任务管理器(Task Manager)。
- 在任务管理器(Task Manager)窗口的详细信息(Details)选项卡中，找到lockapp.exe进程。右键单击它，然后选择Open file location。
- 如果您的 PC 上运行的 lockapp.exe 进程是正版的，Windows将打开C:\Windows\SystemApps\Microsoft.Lockapp_ 文件夹，文件夹名称中的下划线后跟一系列可能会更改的数字和字母，具体取决于您的Windows版本（例如Microsoft.Lockapp_cw5n1h2txyewy）。
但是，如果在文件管理器(File Manager)中打开的位置不在 C:WindowsSystemApps 文件夹中，您可能会认为该进程是恶意的。您需要检查并从您的 PC 中删除恶意软件(check and remove the malware)，然后才能安全地再次开始使用它。
保护和维护 Windows 10 安装(Protecting and Maintaining a Windows 10 Installation)
Lockapp.exe是一个合法的Windows 10系统进程，就像ntoskrnl.exe等一样。禁用它应该不会导致问题，但如果您的 PC 不稳定，您需要采取其他步骤来保护和维护您的系统。您可以首先更新(keeping your PC updated)您的 PC并定期检查您的 PC 是否存在恶意软件。(checking your PC for malware)
如果您的 PC 仍有问题，可能是时候考虑重新安装全新的 Windows 10(fresh Windows 10 installation)了。当然，高CPU和RAM问题可能表明硬件存在问题，因此，如果您面临速度变慢的问题，可能是时候投资一些新的 PC 升级(invest in some new PC upgrades)以让您的 PC 再次平稳运行。
What Is Lockapp.exe in Windows 10 and Is It Safe?
When you switch on a Windows PC, a number of hidden system services and processes kick into action. These procesѕes determine how Windows аppears on your screen, how your device connects to your local network, how you access connected dеvices, sign into Wіndows, and more. Without them, your PC won’t work.
One of the more unusual processes that you’ll see in Windows 10 is the lockapp.exe process. This isn’t just any old executable file, as lockapp.exe is responsible for drawing part of the lock screen (the screen you’ll see before you sign in). If you’re curious to learn more about this system process, here’s what you’ll need to know.
What Is lockapp.exe and Is It Safe?
When you first load your Windows 10 PC, you won’t immediately see a sign in prompt—you’ll see a background, a clock, and the date, as well as any other status items you’ve added, including your network connectivity and battery levels. This is the lock screen, which is nothing more than a glamorous splash screen for your PC.
The lockapp.exe process is what generates and controls this screen. It doesn’t do much else and shouldn’t really cause much trouble to your system. While some users have reported high CPU and RAM usage from time to time, this is very much an unusual situation, as lockapp.exe shouldn’t use much during normal usage.
When you sign in, lockapp.exe should be dormant or hidden, waiting until you lock your PC or sign out again. As a genuine system process, lockapp.exe is entirely safe, but in the rare event that malware is masquerading on your system with the same file name, you can check if it’s genuine by using the steps below.
Can lockapp.exe Cause High CPU, RAM or Other High System Resource Usage?
In normal usage, the lockapp.exe process should use a very limited amount of your system resources—we’re talking a few megabytes of RAM here and there. CPU usage is also likely to be limited during the sign-in process, and should be zero once you’ve signed in.
This is because lockapp.exe is either in “suspended” mode once you sign in (meaning it isn’t actively running) or it’s stopped and hidden completely. You can check this yourself using the Task Manager, but it should be the same for all Windows 10 users.
Troubleshooting lockapp.exe Issues on Windows 10
However, there are reports online that lockapp.exe causes some CPU and RAM issues. This is unusual and could be caused by a bug or corrupt system files. If you suspect your system files are corrupted, you can run the System File Checker (SFC) tool.
- To do this, right-click the Start menu and select the Windows PowerShell (Admin) option.
- In the new PowerShell window, type sfc /scannow and select the Enter key on your keyboard.
The SFC tool will take some time to complete a scan of your system. If it detects any corrupt files, it’ll use a reserved snapshot of your system files to restore them. You may need to restart your PC once this is done.
If SFC doesn’t detect corrupt files, but your system is out-of-date, you might be missing out on important bug fixes. To resolve this, you’ll need to check for any updates.
- You can check for updates in Windows Settings. Right-click the Start menu and select Settings to open this menu.
- In the Windows Settings menu, you’ll need to select Update & Security > Windows Update to view your update options. If there are any available updates, select the appropriate option to download and install them. Otherwise, select Check for Updates to begin a search.
If there are any available system updates, follow the on-screen instructions to download and install them, then restart your PC to apply them in full. While this isn’t guaranteed to resolve any issues with the lock screen overlay, it will ensure you have the most recent available bug fixes installed.
How to Disable lockapp.exe on Windows 10
While lockapp.exe is a system process, it isn’t as important as dwm.exe and other critical processes. Disabling it will take you straight to the login prompt.
- To disable the lockapp.exe process, you’ll need to create a new Windows Registry entry. To do this, right-click the Start menu and select Run.
- In the Run dialog box, type regedit, then select OK.
- Using the registry editor, locate the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization key. If it isn’t there, create it by right-clicking the Windows key, then selecting New > Key. Once you’ve located (or created) this key, right-click the white pane on the right, selecting New > DWORD (32-bit) value from the list. Name the new value NoLockScreen.
- Double-click the new value, then type 1 in the Value data box. Select OK to save.
Once saved, the lock screen overlay will be disabled and lockapp.exe won’t activate. The next time you lock your PC or sign in, you’ll be presented with the sign in prompt directly—the overlay won’t appear.
Configuring the Lock Screen
The lock screen is configurable, allowing you to add certain notifications, such as the number of unread emails in your inbox. To configure this, you’ll need to use Windows Settings.
- Right-click the Start menu and select Settings to begin.
- In the Settings menu, select Personalization > Lock screen. From here, you can change the lock screen background and add other apps to view their “quick status” notifications. This could include your calendar, inbox, news app, and more.
How to Check Whether lockapp.exe Is Genuine
Windows 10 is better at protecting users from malware that pretends to be genuine system processes than earlier Windows versions, but it isn’t impossible that malware like this could infect your PC. If you want to check that lockapp.exe is genuine and safe to run, you can do so using Task Manager.
- To launch Task Manager, right-click the Start menu and select Task Manager.
- In the Details tab of the Task Manager window, find the lockapp.exe process. Right-click it, then select Open file location.
- If the lockapp.exe process running on your PC is genuine, Windows will open the C:\Windows\SystemApps\Microsoft.Lockapp_ folder, with the underscore in the folder name followed by a series of numbers and letters that could change, depending on your version of Windows (e.g. Microsoft.Lockapp_cw5n1h2txyewy).
However, if the location opened in File Manager isn’t in the C:\Windows\SystemApps folder, you can probably assume that the process is rogue. You’ll need to check and remove the malware from your PC before you can safely begin using it again.
Protecting and Maintaining a Windows 10 Installation
Lockapp.exe is a legitimate Windows 10 system process, just like ntoskrnl.exe and others. Disabling it shouldn’t cause issues, but if your PC is unstable, there are other steps you’ll need to take to protect and maintain your system. You can start by keeping your PC updated and checking your PC for malware on a regular basis.
If your PC is still having issues, it’s probably time to consider starting again with a fresh Windows 10 installation. Of course, high CPU and RAM issues could point to struggling hardware, so if you’re facing a slowdown, it might be time to invest in some new PC upgrades to get your PC running smoothly again.
