ReadyBoot is a mechanism to help you speed up your computer’s boot time. Each time you turn on your computer, Windows keeps track of the way your computer starts and the programs which are usually accessed in the startup process. Windows readily save this information in the form of small files in the “Prefetch” folder. The next time you turn on your computer, Windows refers to these files to speed up the startup process.
The Prefetch folder is located under the Windows system directory and is self-maintaining. There is no need to erase its contents as it will only slow down the boot process as Windows will not be able to access the files it saved and will boot in the traditional way.
What is the main Difference between ReadyBoot and ReadyBoost?
Let’s start by defining the mechanics of both the processes. On systems with more than 700MB of RAM, ReadyBoot uses information from 5 previous boots to create a plan for a boot-time memory cache. It will try to prefetch the files needed in the future onto the RAM beforehand. The memory used by ReadyBoot is freed up after around 90 seconds or immediately if another process needs the memory.
To put it in simple terms, if you have a system where your system is booted from an SSD, ReadyBoot may not improve the boot time by a lot. However, it will try to utilize your fast RAM so it can serve as a fast cache for the disk. At this moment, even the fastest SSD’s are slower than your RAM so it does improve the boot time by a little.
ReadyBoost, on the other hand, is meant for utilizing the flash memory for the swap file. If you have an SSD, there is no point in using the ReadyBoost utility as it will be slower. You may see a message pop-up whenever you plug in a fast USB flash into your computer about whether you want to use it for ReadyBoost or not.
What does the Error Condition under Discussion mean?
This error mainly occurs if the memory allocated to the ReadyBoot service is less than the service actually needs. Therefore it is unable to make the small files which we discussed earlier and your computer is forced into not using the service to its potential. The default size of ReadyBoot in most computers is 20MB which may prove to be less over time. We can try changing the allocation size and see if this solves the error message.
- Press Windows + S, type “performance monitor” in the dialogue box and open the application.
- Expand “Data Collector Sets” and click on “Startup Event Trace Sessions”. Look for “ReadyBoot” using the navigation pane present at the right-side of the screen and double-click it.
- Select the tab “Stop Condition”. Now increase the size located at the near bottom of the screen. The ideal size if 128 MB. It isn’t much space but it suffices for the application to function normally.
- Press Apply to save changes and exit.
Now restart your computer. To check if the error condition got fixed, follow the steps listed below.
- Press Windows + R, type “eventvwr.msc” in the dialogue box and press Enter.
- Now you can check in the event viewer if the error message happened recently. Furthermore, you can also navigate to the directory “C:\Windows\Prefetch\ReadyBoot” and check if space is more than the 20MB which we defined earlier.
What are the Side effects on my Computer if the Error Message is Still there?
According to an official statement by Microsoft:
The logging of this error will not affect the operation of your computer.
So to sum up, this error will not in any way affect the way your computer operates or will cause any loss of functionality. It is only used to speed up your computer by increasing its boot time. If Windows is unable to access this utility, it will switch to booting the traditional way and boot the operating system without consulting the memory table which was built because of this service. Do note it will slightly increase the boot time but that’s all there is.

It may cause a slow boot time when you turn on your PC. On the other hand, the operation of the device won’t be affected because it is just related to boosting the boot time of a computer. There is nothing to worry about this, by following some easy steps, this issue can be solved in a minute. So, without any further discussion let’s see the steps to solve this issue.
What Is ReadyBoot and Why Does The Error Happen?
Readyboot is a feature of Microsoft Windows which is implemented in Windows to boost the performance without embedding additional RAM. It boosts up the boot time of the computer. It is suggested according to users, that the maximum size should be set to 256 MB but not more than that. However, storage of 128 MB is inch perfect for avoiding any circumstances.
“ReadyBoot Stopped” or “Kernel Event Tracing- Error 3” this issue occurred when the allocated storage size is less than the required one. Default size of 20 MB is allocated for ReadyBoot, and when the file size exceeded more than the allocated storage, an error arises.
The one and only solution is to increase the allocated size of Readyboot. There are some easy steps by which you can fix this.
Step 1: Go to the search option manually or press Windows + S and type Performance Monitor.
Step 2: Open Performance Monitor and expand Data Collector Sets.
Step 3: After expanding, click on Startup Event Trace Sessions and look for ReadyBoot on the right side of the screen. Double click on ReadyBoot

Step 5: Then apply the changes and click ok.
Now exit and restart the PC. If you want to check if the issue is solved or not then open the Run dialog box by pressing Windows + R then type “eventvwr.msc” and press enter.
Frequently Asked Questions
What Prefetch folder actually is?
Prefetch is known as a file that is used to help windows load faster. Readyboot system, a feature of Microsoft windows that traces boot time history and analyze boot time. It helps to speed up the booting time by tracing previous boot history and the programs while starting your computer. Windows save this information in a form of small files. These files are kept in the Prefetch folder.
Can the Prefetch files be deleted?
Yes, you can delete the files. But it is suggested to do not to delete them as it helps windows to speed up the boot time. Prefetch files take a little space and it won’t bother you unless you are running out of space and then you can delete them to regenerate the space.

Здравствуйте.
Перед Новым годом установил на ПК новый SSD (Goodram Iridium Pro), а вместе с этим в голове родилась идея установки долгожданной Windows 10 x64 (Корпоративная). Терабайтный жёсткий диск, разумеется, решил использовать для файлов.
На первый взгляд, всё было бы хорошо, если бы не одно НО. При нажатии на кнопку завершения работы, компьютер иногда выключался, а иногда перезагружался. Перечитав форумы, я настроил электропитание в ПУ, накатил последние обновления Windows, обновил BIOS, обновил драйверы, а также поменял значение в ветке: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WMI\Autologger\ReadyBoot на «4».
Теперь при нажатии кнопки выключения, компьютер выключается, но недавно в журнале ошибок Windows увидел ежедневную ошибку: Сеанс «ReadyBoot» остановлен из-за следующей ошибки: 0xC0000188
