"ReadyBoot"

It is some time now that I am getting very frequently the following message:
[quote]
The maximum file size for session "ReadyBoot" has been reached. As a result, events might be lost (not logged) to file "C:\Windows\Prefetch\ReadyBoot\ReadyBoot.etl". The maximum files size is currently set to 20971520 bytes.

I have read that "this is nothing" and just go on as it is not there.
But the actual boot time has deteriorated considerably.

Is there any solution or improvement that can bring back boot times in decent levels?
Are there any processes that I would have to check if they are activated or not?

It is not Ready Boost I am asking but Ready Boot.
Nothing to do with any USB stick.

Didn't happen to disable the ReadyBoost service did you? As shown in the quote above the service is required for ReadyBoot to function.

Another thing I found in regard to that error is to change the following in regedit,

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WMI\Autologger\ReadyBoot

The default value for MaxFileSize is decimal value 20. Double-click MaxFileSize and set the value larger than 20 e.g.60

Thanks for the input.
ReadyBoost was disabled so I enabled it back. Unfortunately no improvement yet (but I wiil try also the registry tweak). In principle, I would expect that this file would be overwritten by Windows automatically when size limit reached.

And just after that I panicked...

Checking around in the system, it seems that I have a much worst problem than this. Please look at the attachment, screenshot from my registry.
Doc1.docx
See the first 8 entries and the very last in HKEY_CURRENT_USER?
Do you know how these entries could show up there (for example by BSOD's or memory crashes)?
Would it be safe just to delete them (all have the value that is shown for the first)?
Do you know of any utility that analyses the boot process (I remember something like it for XP)?

If it works, don't fix it.

With that said, there is a program which has even received the right to use the Win 7 compatible logo which may, just may, help you.

That program is CCleaner. CCleaner has two main parts-one for doing much the same as Disk Cleanup and the other is to clean the registry.

Now there are those who will talk about registry cleaners as if they are worse than a sexually-transmitted disease. I have used CCleaner for quite awhile on Vista and Windows 7 systems. I have never had any problems.

I recommend that you download and run CCleaner. I use it daily.

CCleaner - Optimization and Cleaning - Free Download

I just ran it, but these entries are not even listed in CCleaner issues list.
So, I guess the only option is to make a restore point and delete manually?
Any ideas/knowledge on how they are created (so I do something to avoid this)?

Try a System Repair.

SYSTEM REPAIR USING A SYSTEM REPAIR DISK

1) Make a System Repair Disk (WIN key| type Create System Repair Disk | ENTER key)
2) Insert System Repair Disk into optical reader.
3) Shutdown your computer.
4) Boot up your computer from the System Repair Disk (if needed, Power on button, immediately hit F2 key, change boot order to have boot from cd/dvd first).
5) Wait while a mini-version of Windows is loaded and finally the System Recovery Options dialog appears.
6) SYSTEM RECOVERY OPTIONS dialog |
will show Select a keyboard input method |
NEXT button
7) SYSTEM RECOVERY OPTIONS dialog
will search your system for installed versions of Windows.
8) SYSTEM RECOVERY OPTIONS dialog |
select the Use recovery tools that can help fix problems starting Windows radio button |
NEXT button
9) SYSTEM RECOVERY OPTIONS |
will show Choose a recovery tool and list the following |
System Repair
System Restore
System Image Recovery
Windows Memory Diagnostic
Command Prompt
10) Click on System Repair and run system repair
11) Repeat running of System Repair 3 times
12) Remove the System Repair Disk CD
13) SHUTDOWN button
14) Power On your computer

You reckon that system repair can delete registry entries ?
(I suppose that I can use the Windows installation disk, right?)
