Windows 10 の動作が遅い理由を見つける方法

3. 詳細を選択してください タブをクリックして実行中のプロセスを並べ替えます:

<強い>A.タスクの終了:

1. 問題のプロセスを右クリックし、[タスクの終了] を選択します。

2. 2 ～ 3 分待ってから、[パフォーマンス] を確認します CPU 使用率が低下している場合は、タブを開きます。

3. 使用量が通常のレベルに戻った場合は、次のいずれかを試してください:

• Web を検索して、問題に関連する解決策を見つけてください
• 問題のプロセスがサードパーティ製アプリケーションに属している場合は、システムからアプリケーションをアンインストールしてください。
• 問題のプロセスが Windows サービスに属している場合は、システム上の問題のサービスを完全に無効にしてみてください。

B. Stop Service.

1. Right click on the culprit process and select Go to service(s) (if this choice is available).

2. Right click on the culprit service and select Stop .

3. Wait 2-3 minutes and then see at Performance tab if the CPU usage is decreased.

4. If the usage returns to normal levels, then try one of the following:

• Search the WEB, for a solution related to your problem.
• If the culprit service, belongs to a third party application, then uninstall the application from your system.
• If the culprit service, is a legitimate Windows service, then try to permanently disable the service.

C. Using the Process location information, try the following:

• If the culprit process, belongs to a third party application, then uninstall the application from your system.

Method 2. How to Troubleshoot SVCHOST.EXE Process.

In some cases it is not easy to identify (by using the above method) which exact process (or service) uses too many CPU resources, because Windows – by design – can use a single process (e.g. the "svchost.exe" process), that loads several other critical services at the background. In that case, you have to find which processes are running under the "svchost.exe" process and then to troubleshoot the culprit service. To do that:

1. Select the Performance tab and then Open Resource Monitor .

2. At the Resource Monitor window, choose the CPU* tab and make the following changes:

(1) Short the running processes by CPU* usage (greater values on the top) and
(2) Expand Services.

* Note:If you want to troubleshoot Memory usage problems, then click/sort by "Memory" usage.

3. On the top window, select the first process on the list, that uses the most CPU (or Memory) resources.
4. Then, look at the Services section – at the bottom window – to view all the services that are loaded under the selected process.

For example:As you can see at the screenshot below, the SVCHOST.EXE process is handle the following services:Superfetch, Network Connection Broker, Windows Driver Foundation, etc..

5. Now put the Resource Monitor and the Task Manager windows, next to each other. (as shown below)

5 . At the Resource Monitor window, do the following:

• At the Processes pane:
  (1) Select the first process in the list that consumes the highest CPU or Memory resources (e.g. the "svchost.exe" process)
• At the Services pane:
  (2) Sort the services by CPU 利用方法。 (greater values on top) *
  (3) Notice the name of the first service(s) in the list.

* Notes:If you want to troubleshoot Memory usage problems, then click/sort by "Memory" usage.

For example:As you can see at the below screenshot, the first service under the "Services" section is the "SysMain" service (Superfetch).

6. At Task Manager window, choose the Services tab.
6a. Locate in the list, the service you noticed before (at Step-1) and then temporarily stop that service. To do that:

1. Select the Service
2. Right-click on it, and choose Stop Service.

7. Now wait 2-3 minutes and then see at the Resource Monitor window, if the CPU usage has changed. At this point two things can happen:

A. The CPU usage is still High.
– At this case, proceed and disable (using Task Manager window), the next service(s) that is listed at Resources Monitor> Services section, until you find which of the listed services causes your CPU (or Memory) to work at high levels.

B. The CPU usage has decreased.
– At this case, search on the WEB for a solution related to your problem or disable the culprit service permanently.

How to disable a Windows Service permanently.

1. Open Services マネジャー。 To do that use one of the following options.

• Option 1. From Task Manager window, click the Services tab and then select Open Services .

• Option 2. Simultaneously press Windows key + R   to open the run command box, type:services.msc and press Enter.

2. At Services management window, right-click at the culprit service and choose Properties .

3. Change the Startup type to Disabled , press OK and restart your computer.
