Readyboot and Superfetch

Hi Aber,

Thank you for posting the question in Microsoft Community!

You are getting message that The maximum file size for session "ReadyBoot" has been reached.

I have to let you know that ReadyBoot.etl log that tracks all file activity at boot time.

Since all file activities done at boot time (even system updates and spyware scans) accumulates in this file, it may fill with obsolete information. The fix is to set the ReadyBoot.etl into Circular logging mode, so that only the most recent file access activity is tracked.

To do so:

a.     Click start, click control panel

b.     Click administrative tools, performance monitor

c.     Expand left side tree entry for Data Collection Sets

d.     Highlight Startup Event Trace Sessions

e.     Open the ReadyBoot line (click it)

f.      Select the File tab

g.     Select the circular option

h.     Click apply and ok and restart the computer.

Superfetch service improves the performance and hence it is suggested to set its startup as automatic.

Changing the registry value would increase the max size and it will reach the limit again and then again he may change the registry value.

Disclaimer: Serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up the registry, click the following article number to view the article in the Microsoft Knowledge Base:
