ReadyBoot Folder Won't Regenerate

Hi.

My Prefetch folder (C:\Windows\Prefetch) was deleted, so I manually recreated it. Now, many .pf files have been regenerated, which is expected. But several days have past and I've restarted my computer a few times, and I still don't get a complete ReadyBoot folder.

I dug up this thread and followed the notes there.

• I executed "sfc /scannow" in Command Prompt, which found no integrity violations.
• I opened Performance Monitor and found that ReadyBoot (located under "Data Collector Sets" -> "Startup Event Trace Sessions") was disabled, so I enabled it and restarted. The ReadyBoot folder was recreated, but it's sitting empty. Furthermore, I see that ReadyBoot has disabled itself in the Performance Monitor again.

Also, whenever I open the Prefetch folder, I get a warning message stating that I don't currently have permissions to access this folder. I need to press "Continue" to be able to open the folder and view the contents. I notice that no other folder in C:\Windows\ gives me this warning. So perhaps the permissions on the Prefetch folder aren't set correctly.

The Superfetch service is running and set to automatically start.

Can anyone help me get ReadyBoot running again? Does anyone know what all the proper permissions on the Prefetch (and ReadyBoot) folders are supposed to be? Is it normal for ReadyBoot to be disabled in Performance Monitor?

Thank you.

I would start by checking those permissions issues. Then maybe it's just a matter of restarting five or six times, who knows.

Just a shot in the dark.

Here you go:

Code:

PS C:\Windows> icacls .\Prefetch\
.\Prefetch\ BUILTIN\Administrators:(F)
            BUILTIN\Administrators:(OI)(CI)(IO)(F)

Successfully processed 1 files; Failed processing 0 files
PS C:\Windows> icacls .\Prefetch\ReadyBoot\
.\Prefetch\ReadyBoot\ BUILTIN\Administrators:(I)(F)
                      BUILTIN\Administrators:(I)(OI)(CI)(IO)(F)

It is normal for ReadyBoot to be disabled if you have a SSD (don't know if you do) - at least mine is and I never touched it after clean install.

I don't know the default for HDD (don't have one) but you can reset it to whatever Windows thinks is correct by running winsat formal -v from elevated command prompt.

So you don't have a folder named ReadyBoot that has files in it in your Prefetch folder? Because I do have an SSD. Maybe I'm thinking that the ReadyBoot folder should be present when -- like you say -- it shouldn't be for an SSD.

I have the folder C:\Windows\Prefetch\ReadyBoot\ but it is empty.

Do you have a folder named "ReadyBoot" in your Prefetch folder? Does it have files in it? Is your copy of Windows installed on an SSD or HDD?

Also, whenever I open the Prefetch folder, I get a warning message stating that I don't currently have permissions to access this folder. I need to press "Continue" to be able to open the folder and view the contents.

1. If Superfetch is enable, I think you'll get that warning. I disabled Superfetch and don't get that warning when I open the c:\Prefetch folder
2. The only two permissions on my c:\Prefetch folder are my User & Administrators and both have Full Control.

1. Yes, I have the ReadyBoot folder, but it's empty because I have Superfetch disabled
2. Yes, Windows is installed on a SSD
3. As previously mentioned ... I don't think the ReadyBoot files get re-created until 5 reboots

Note: I have intentionally disabled Prefetch & Superfetch
1. SuperFetch Service is Disabled
2. Made the following reg edits
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
EnablePrefetcher = 0
EnableSuperfetch = 0

My Readyboot folder contains the following files (mechanical HD):

Trace5.fx
Trace6.fx
Trace7.fx
Trace8.fx
Trace9.fx
rblayout.xin

I guess it must be empty for SSD drives. I will check this afternoon.

Well I don't want to disable Superfetch, even though I've an SSD. And I'll check after a few more reboots to see if the ReadyBoot folder fills up. Based on the responses in this thread (including yours), I think everything is normal if the ReadyBoot folder is empty. So maybe I'm just drawing from past experiences, since this is the first computer build that I've put Windows on an SSD. Normally I've install on an HDD, so am used to see files in the ReadyBoot folder.
