阅读13分钟内存占用高但看不到进程，多数是内核与驱动占的分页池、非分页池和系统缓存造成的：任务管理器进程列表加起来才两三 GB，性能页却显示已用十几 GB，进程页本来就不统计内核态那部分。以下方法在 Windows 10/11 实测可用。
这类情况多是系统环境、旧驱动残留或后台常驻服务引起的，内存条本身大多没坏，不必急着重装系统或送修。
适用系统：Windows 10/11；最后更新：2026-11-10。
为什么进程加起来没多少，内存却满了
Windows 11 22H2 上就能看到这个现象：进程页几十个进程数下来一共 2.6 GB，切到性能页，「使用中(已压缩)」写着 10.8 GB，「已提交」12.4 GB，而分页文件只有 2 GB。
打开资源监视器还会发现，一个叫 System 的进程提交大小就有 4 GB 多，Registry 几百 MB，这些在任务管理器里要么被折叠，要么根本不显示。已提交减去所有进程的工作集，差额就是分页池、非分页池和驱动锁定的物理内存，它们归内核管。

先看清差额有多大，再决定去查驱动还是查后台服务，能省下大量盲目关进程和重装的时间。
方法1 先看差值到底在哪
结论先说：进程页的数字和性能页的数字对不上，多出来的占用就在内核与驱动那一侧。
任务管理器「内存」里的「使用中(已压缩)」统计的是用户态进程的工作集，系统还会把不常用的页面压缩起来，所以它常常比实际占用看着小很多。
操作步骤
- 按 Ctrl+Shift+Esc 打开任务管理器，切到「性能」标签，左侧选中「内存」
- 记下三个数字：「使用中(已压缩)」、「已提交」，以及括号里的分页文件大小
- 已提交约等于 使用中 + 分页池 + 非分页池 + 驱动锁定，若已提交远大于进程占用总和，问题就不在进程列表里
- 点这一页下方的「打开资源监视器」，可以直接跳到方法2
- 任务管理器的「进程」页只统计用户态进程的工作集，内核态占用不会出现在这里

两个数字差着好几 GB，就不用再一个个关进程试了，直接往下查是谁在占。
方法2 用资源监视器按提交大小排序
资源监视器比任务管理器细一层，System、Registry 和寄生在 svchost 里的服务都能单独列出来。
它统计的是提交大小，也就是这个进程向系统要了多少内存，比工作集更接近真实占用。
操作步骤
- 按 Win+R 输入 resmon 回车，或点性能页下方的「打开资源监视器」
- 切到「内存」标签，点上方进程表的「提交大小」列头，让它降序排
- 重点看 System、Registry、svchost.exe(网络服务)、svchost.exe(本地服务) 这几行，它们在任务管理器里往往被折叠
- 再点「硬错误/秒」列头排序，硬错误高的进程说明它的内存正在被换出换入
- 右侧的内存条里，备用过大只是缓存，不算真占用；已修改和已提交才是要盯的

排在前面的是驱动相关进程，先记下名字再去查它的驱动版本。System 和 Registry 属于系统进程，结束不掉也不该结束。
用「软领驱动大师」更省事
系统优化能把非必要的启动项与后台常驻服务整理掉，减少登录之后一直挂在内存里的常驻进程，重启后再对照空载占用的变化。清理前先记下原状态，只关非必要项。
内存对不上时，真正费时间的是判断问题出在驱动、服务还是启动项。全面诊断会把系统里的驱动、服务、启动项整体过一遍，省去在设备管理器、services.msc 和 driverquery 之间来回切换对照，先给一个可判断的结论，再决定动哪一项。

方法3 用管理员 PowerShell 求和核对
把所有进程的工作集加起来，再和性能页的「使用中」相减，差额就是内核态的占用，范围能直接锁死。
WS 列的单位是字节，除以 1073741824 才是 GB。输出里的数字不带单位，别顺手当成 MB 看。
操作步骤
- 开始菜单搜索 PowerShell，右键「以管理员身份运行」
- 执行 Get-Process | Sort-Object WS -Descending | Select-Object -First 15 Name,WS，先找前 15 个大户
- 再执行 Get-Process | Measure-Object WS -Sum，把求和结果除以 1073741824 换成 GB
- 用这个数和性能页的「使用中」相减，差额稳定在几 GB，基本可以判定是分页池与非分页池
- 补两条计数器：Get-Counter '\Memory\Pool Nonpaged Bytes' 和 '\Memory\Pool Paged Bytes'，反复刷新，看是不是一直在涨

两项计数器只涨不跌，说明有驱动或内核组件在持续申请内存，接着往下查是谁。
方法4 查内核与驱动占用
到这一步要分清两件事：内存是被系统缓存拿走了，还是被某个驱动锁住不放。
RAMMap 能按物理页统计，driverquery 能列出所有驱动，两边对着看，谁随时间只涨不跌就很明显了。
操作步骤
- 从 Sysinternals 官方页面下载 RAMMap，解压后右键以管理员身份运行
- 打开 File Summary 标签：Metafile 异常大是系统缓存与元数据，Driver Locked 异常大是驱动锁定的物理内存
- 再切到 Physical Pages 和 Use Counts，对照分页池、非分页池的增长情况
- 管理员命令提示符执行 driverquery /v，重点看网卡、显卡和杀毒软件的过滤驱动；某一项内存随开机时间只涨不跌，就优先更新或回滚它
- 怀疑系统文件损坏引起内核内存泄漏，先执行 sfc /scannow，再执行 DISM /Online /Cleanup-Image /RestoreHealth；驱动文件都在 C:\Windows\System32\drivers
- 更新驱动后如果出现 0x0000007B 这类启动错误，进安全模式，用设备管理器把驱动回滚

回滚或卸载驱动前先备份重要文件。硬盘本身有坏道或 CRC 校验错误时，任何驱动操作都要放在备份之后再做。
方法5 处理提交量并梳理后台常驻
占用来源确认之后，把提交量和后台常驻一起收一收，重启再看空载占用有没有回落。
分页文件被手动改小过，是已提交偏高的常见原因，先把它改回系统自动管理。
操作步骤
- 按 Win+R 输入 sysdm.cpl，进「高级」标签，点性能「设置」→「高级」→ 虚拟内存「更改」
- 勾回「自动管理所有驱动器的分页文件大小」，或手动给系统盘留出与物理内存相当的大小，确定后重启
- 按 Win+R 输入 services.msc，逐个看启动类型为「自动」的服务及其描述，非必要项右键「属性」把启动类型改成「手动」，改前先记下原值
- 任务管理器 →「启动应用」标签，把不常用的项右键「禁用」，这里是登录时一次性占用的大头
- 重启后空载 5 分钟，再复查性能页的已提交与已用；还是偏高就回到方法4 继续盯驱动

每改一项就重启看一次数字，才知道是哪一个改动起了作用。
大家常问
内存占用高但任务管理器看不到进程，是不是中病毒了？
可能性不大。先看性能页的「已提交」和资源监视器里 System、Registry 的提交大小，这类占用由内核与驱动产生；把杀毒软件停掉之后数字没变化，就可以先排除这个方向。
已提交内存远大于所有进程占用之和，算不算内存泄漏？
要看它是不是持续上涨。开机放一晚上，用 Get-Counter '\Memory\Pool Nonpaged Bytes' 前后对比，稳定在某个数值属于正常的缓存与分页池，只涨不跌才按驱动泄漏处理。
RAMMap 里 Driver Locked 很高是什么原因，怎么降下来？
多是网卡、显卡或杀毒软件的过滤驱动长期锁定物理内存。用 driverquery /v 对照开机时间找出只涨不跌的那一项，更新到厂商官方版本，还高就回滚到上一版。
16G 内存开机就占到 70% 正常吗，Win11 是不是更吃内存？
Win11 会主动用空闲内存做缓存，已用看着高、备用也大，属于正常调度。判断标准看硬错误/秒是否持续偏高、切换程序是否明显卡顿，单看百分比说明不了问题。
改完虚拟内存重启蓝屏 0x0000007B，怎么进系统恢复？
这是启动控制器驱动不匹配的报错。开机按 F8 或强制关机三次进恢复环境，选安全模式，进设备管理器回滚存储控制器驱动，再把分页文件改回自动管理。
