Windows comes with a Memory Diagnostic tool that helps verify and test the RAM of your device. Users launch it to check the RAM for any issues present. However, some users face that this tool is stuck or working improperly in their system. In this article, we have suggested three ways you can fix Windows memory diagnostic tool stuck or not working in your Windows OS.
Page Contents
Depending on the RAM size, the Memory Diagnostic Tool can take anywhere from 15 minutes to more than 20 hours in the extended mode to finish its testing process. The app is generally known to get stuck at 1% and 21% progression for hours. It could be due to some system glitch. When this happens, you can try the following fixes.
Fix 1: Perform a Clean boot before running the tool
This could be your solution if a third-party software is preventing this tool from completing the test. The Windows starts with a minimal set of drivers and startup apps in the clean boot mode. It allows you to determine if the background program/app is interfering with other programs. To perform a clean boot, follow the steps below.
- Open the Start Menu and search for System Configuration.
- In the Windows that opens, go to Services tab.
- Check the Hide all Microsoft services box. Then, click on Disable all.
- Click Apply to save the changes.
- Now, right click on the Windows icon and go to Task Manager in the menu that pops.
- Open Startup apps tab.
- One by one, click on all the items that have their status as enabled, and click on the disable button.
Do ensure that all the services in the Startup apps tab have their status as Disabled.
- Close the Task Manger and go to the System Configuration Window. Click OK.
Now Restart your PC. Your system will start in a Clean Boot mode. Try running the tool again and see if the issue is resolved.
Fix 2: Use MemTest86
Using Memtest86 will help you determine whether the issue is with the RAM or the tool. If this test completes without any error, you will need to run the memory diagnostic tool once again to check if the issue at hand is solved. To run the test, you first need to make sure that you have a working USB drive and that it is empty, as it is to be used as a bootable drive. Follow the steps below to go ahead.
- Download MemTest86 from its website (https://memtest86.com).
- When it is done, right click on the downloaded folder and select Extract All. And then click on Extract.
- Next, connect the USB drive with your device.
- From the recently extracted folder, run imageUSB.exe file in your system.
- When the connected and detected drive is ensured, click on the Write button.
- The process will take some time. Once it is done, close the ImageUSB tool by clicking on Exit.
All you need to do now is to shut down your PC, Insert the USB flash, and restart the system. The tool will automatically run after your PC Restarts.
Fix 3: Wait till the tool completes the process
At times, tool being stuck for a few hours is not a glitch. When run in extended mode, it may get stuck at 21%, 88%. 89%, and 90% progress for more than 4 hours. Unless the progress is stuck at 21% for an entire day, you can let it run and finish the process without any interruption.
Of course, you have a couple fixes suggested here to try if it is stuck for an entire day without any progress.
Hence, we have covered all the fixes you can try on your own. If the problem still persists, the issue could be deeper, and you would probably need PC repair tool to fix it. You need to simply download and install it from the web, Start the Scan and select the option of Repair All. This ultimate solution will fix the problem for sure.

The most prominent cause of the issue discussed is that some systems have really large RAM, and in that case, it is perfectly alright for the Windows Memory Diagnostic Tool to take a long time.
Many users have claimed that the tool took up to 12 hours to complete the job. Thus, the first approach when you encounter this problem should be to leave your computer running or with the memory diagnostic tool overnight. If it doesn’t resolve the problem in the discussion, read further.
2] Run it in Clean Boot State
The second cause could be interference by third-party software. In this case, you can consider rebooting the system in a clean boot state. The procedure to reboot your system in a clean boot state is as follows:
Press Win+R to open the Run window and type the command msconfig. Hit Enter to open the System Configuration window.
In the System Configuration window, go to the Services tab.
Check the box corresponding to Hide all Microsoft services.
If any other application is still checked, the Disable all button would be active. Else, that button would be greyed out. Click on the Disable all button.
Now click on Apply and finally on OK.
It will prompt you to restart the computer and you can do the same.
If the Windows Memory Diagnostics tool works fine after the reboot, then you can consider uninstalling recently installed programs that could have caused the trouble.
If the Windows Memory Diagnostic tool still does not complete its job, you can exit it and then use another free third-party tool like MemTest86.
How long should Windows Memory Diagnostic Tool take?
The Windows Memory Diagnostic Tool typically takes 10 to 15 minutes for a basic test. However, the “Extended” test option can take over half an hour, depending on the amount of installed RAM and your computer’s hardware.
How do I get out of Windows Memory Diagnostic?
To exit Windows Memory Diagnostic, press the Escape (ESC) key at any time during the test. This will stop the diagnostic process and return you to Windows. You can also restart your computer to exit the tool and go back to your Windows operating system.

Вы когда-нибудь задумывались, как обнаружить плохую оперативную память в вашей системе? Что ж, это делается с помощью скрытого встроенного инструмента Microsoft под названием Windows Memory Diagnostic tool (WMD Tool). Обычно, когда система обнаруживает проблему с оперативной памятью, этот инструмент выводит уведомление пользователю, как показано ниже.
Пользователи могут нажать кнопку «Перезагрузить сейчас», и система перезагрузится и запустит тест. По мере того, как тест продолжается, он показывает ход теста в %. Этот тест занимает значительное количество времени, от получаса до целого дня. Если вы видите, что за последние 20 часов сканирование не продвинулось значительно, это может означать, что средство диагностики памяти Windows зависло из-за некоторых сбоев в системе или неисправного оборудования. Обычно этот инструмент застревает или зависает надолго на 1% или 21%.
В этой статье давайте посмотрим, что можно сделать, когда инструмент WMD завис или завис.
Способ 1: дождитесь завершения теста
После запуска теста требуется много времени для его завершения. Следовательно, рекомендуется запускать этот тест ночью или когда система не используется. Следующие случаи считаются нормальными
- Тест может застрять на 21% примерно на 4-5 часов.
- Вы можете заметить, что тест пройден в этих точках 21%, 88%, 89%, 90% без какого-либо прогресса.
Подождите, пока тест завершится сам по себе. Если тест не заморожен более чем на 20 часов, это не должно быть проблемой. Если вы видите, что тест зависает более чем на 20 часов, это может означать, что есть какая-то проблема с оборудованием. .Например, если в системе 8 ГБ оперативной памяти, состоящей из двух карт памяти по 4 ГБ каждая, у одной из них могут быть проблемы с оборудованием. В некоторых случаях помогало удаление и повторная установка палочек.
Способ 2 — использовать кеш вкл.
1. Пока вы находитесь на синем экране теста памяти, нажмите F1 для доступа к параметрам.
2. Используйте клавишу Tab для доступа к разделу кэша.
3. Теперь используйте клавишу со стрелкой вниз на клавиатуре, чтобы выбрать ВКЛ.
4. Наконец, нажмите F10, чтобы применить и продолжить тест.
Способ 3: Загрузите и используйте MemTest86
1 – Загрузите и запустите инструмент MemTest86 бесплатно здесь
2 – Извлеките загруженный файл.
3 – Вставьте USB в компьютер с Windows.
4 – В извлеченной папке найдите, щелкните и запустите файл imageUSB.exe.
5. Найдите свое USB-устройство в окне ImageUSB и нажмите кнопку «Запись».
6 – нажмите кнопку Выход.
7 — Теперь выключите компьютер. Вставьте USB в ПК и перезагрузите компьютер.
Способ 4: выполните чистую загрузку, а затем запустите инструмент WMD
Шаг 1: Откройте диалоговое окно «Выполнить» в вашей системе. Можно просто одновременно зажать клавиши Windows+r на клавиатуре
Шаг 2: Введите msconfig и нажмите кнопку OK.
Шаг 3: Откроется окно «Конфигурация системы», как показано ниже. Перейдите на вкладку Услуги
Шаг 4. Установите флажок «Скрыть все службы Microsoft». Это отключит все службы Microsoft из приведенного выше списка.
Шаг 5: Нажмите «Отключить все» и нажмите «Применить».
Шаг 6. В том же окне откройте вкладку «Автозагрузка», нажмите «Открыть диспетчер задач».
Шаг 7: В открывшемся окне диспетчера задач в столбце «Состояние» вы можете увидеть приложения, которые включены при запуске. Отключите все приложения, которые включены при запуске.
Шаг 8. В окне «Конфигурация системы» нажмите «Применить», а затем нажмите «ОК».
Шаг 9: Перезагрузите компьютер.
Шаг 10: Нажав одновременно кнопки Windows+r, снова откройте диалоговое окно «Выполнить».
Шаг 11: В пустой текстовой области введите mdsched.exe и нажмите OK.
Шаг 12. В открывшемся окне средства диагностики памяти Windows выберите «Перезагрузить сейчас» и проверьте наличие проблем (рекомендуется). При этом испытание ОМУ снова запустится.
Убедитесь, что тест выполняется до завершения и устраняет проблему.
Это все.
Мы надеемся, что эта статья была информативной. Пожалуйста, прокомментируйте и дайте нам знать, если вы смогли решить проблему с помощью этих исправлений. Мы будем рады помочь, если у вас возникнут какие-либо проблемы.
Спасибо за чтение.
Я вижу, что прошло больше года с тех пор, как был задан первоначальный вопрос, но, пожалуйста, позвольте мне прояснить некоторую путаницу: это нормальное поведение для этого конкретного инструмента.
Даже если у вас хорошая ОЗУ, «Средство диагностики памяти Windows» будет очень часто, если не всегда, зависать на 21% при выполнении расширенных тестов !!! Но он не зависает постоянно … какой бы тест ни выполнялся в это время, он занимает много времени.
Для ясности: если проход с использованием Microsoft Windows Memory Diagnostic Tool зависает на 21% при выполнении расширенных тестов, это НЕ означает, что ваш баран плохой (даже если баран МОЖЕТ быть плохим). Хороший баран тоже будет висеть на 21%.
Вы просто должны оставить его на много-много часов, в зависимости от того, сколько у вас памяти, и других факторов, таких как скорость вашего процессора и контроллера памяти.
Мне также нужно прояснить небольшую дезинформацию о том, как этот инструмент сообщает о своем процентном завершении. WMDT сообщает о ходе каждого прохода в том же поместье, что и Memtest86: 10%, 20% или 50% и т.д. НЕ означает, что 10%, 20% или 50% адресов были проверены. к тому моменту, когда он достиг 21%, большинство физических алгоритмов было протестировано. Пропуск с использованием Extended просто поражает вашего ОЗУ несколькими более различными тестами, чем Standard или Basic, но один из этих дополнительных тестов требует того, что кажется вечным, особенно если у вас больше 4 ГБ. Допустим, что Extended выполняет десять различных тестов / шаблонов / алгоритмов за проход (я не могу вспомнить, сколько на самом деле он работает в Extended, но давайте используем десять, чтобы упростить математику). после того, как один из десяти тестов / шаблонов / алгоритмов будет завершен, он сообщит, что выполнено 10%. после окончания второго из десяти он сообщит о 20% выполненных работ. Какой бы тест / шаблон / алгоритм ни выполнялся, когда он показывает 21%, это занимает очень много времени. опять же, я не говорю, что Extended запускает десять различных тестов (я думаю, что на самом деле это может быть шестнадцать), я просто использую «десять» в качестве примера, чтобы показать, как рассчитывается Процент завершения.
Вы можете проверить это так же, как это сделал WakeDemons3: вращайте палочки оперативной памяти в разных порядках слотов и обратите внимание, что проход все еще зависает на 21%, а не (при условии, что две палочки одинакового размера) на 71% …
I see that it has been more than a year since the original question was asked, but please let me clear some of the confusion up: This is normal behavior for this particular tool.
Even if your RAM is good, the «Windows Memory Diagnostic Tool» will very often, if not always, hang on 21% when running the Extended tests!!! But it is not permanently hung… whatever test is running at that time just takes a long time to finish.
To be clear: if a pass using Microsoft’s Windows Memory Diagnostic Tool seems to hang on 21% when running the Extended tests, it does NOT mean that your ram is bad (even though your ram MIGHT be bad). Good ram will hang on 21% too.
You just have to let it sit for many many hours, depending on how much ram you have and other factors such as the speed of your CPU and memory controller.
I also need to clear up a little misinformation as to how this tool reports its percentage complete. WMDT reports the progress of each pass in the same manor that Memtest86 does: 10% or 20% or 50% etc does NOT mean that 10% or 20% or 50% of the addresses have been tested. the entire amount of physical ram has been tested by most of the many different algorithms by the time it hit 21%. A pass using Extended just hits your ram with a few more different tests than Standard or Basic, but one of those extra tests takes what seems like forever, especially if you have more than 4GB. Let us say that Extended runs ten different tests/patterns/algorithms per pass (i can’t remember how many it actually runs in Extended, but let’s use ten to make the math easy). after one out of the ten tests/patterns/algorithms is finished, it will report 10% done. after the second out of ten is finished, it will report 20% done. Whatever test/pattern/algorithm is running when it shows 21% just happens to take a very long time. again, I’m not saying that Extended runs ten different tests (i think it might be sixteen-ish actually), I’m just using «ten» as an example to show how the Percent Complete is calculated.
You can test this the same way that WakeDemons3 did: rotate the ram sticks in different orders of slots, and notice that the pass still hangs on 21%, not (assuming two sticks of the same size) 71% …
