Tip & How-To about Microsoft Windows 7 Ultimate for PC

Tuneup utilities prefetch data deleted windows 7 slow

Basically, the prefetcher is a Windows component that speeds up the boot process and start times of programs by prefetching data.

I recommend you never delete the prefetch data.

If you or another program delete prefetch data or the folder, this can slow the computer down until the prefetch data is rebuilt. Windows rebuilds this each time on reboot and during program start ups.

If you are using a cleanup utility, turn off any options that delete prefetch data. In CCleaner, this option is unchecked automatically. TuneUp 10 does not have an option for prefetch data and does not seem to delete this data. You may receive a message when using the program that states, "prefetch data deleted" which is informing you the prefetch is empty.

i dont konw how to turn off deleting prefatch data in tuneup utilties 2011


Hello,

TuneUp utilities does not seem to have an option to delete prefetch data, however, you can view all settings in the options menu.

What you may be seeing is simply a notification within TuneUp Utilities that the prefetch data was deleted either by another program or mistakenly by you.

The prefetcher in Windows basically speeds up the computer boot process and start up program speeds. Windows will rebuild this information automatically on each reboot and program start up, so, over time, you will see the problem corrected.

Hi I have win 7, CCleaner, kaspersky 2011 & tuneup utility 2011 the tuneup says "prefetch data deleted" pls help me how to troubleshoot this problem


It is absolutely safe to delete the Prefetch Data. Each time you turn on your computer, Windows keeps track of the way your computer starts and which programs you commonly opened. Windows saves this information as a number of small files in the prefetch folder. The next time you turn on your computer, Windows refers to these files to help speed the start-up process. You may also change the setting of Tuneup Utility not to clear the prefetch data. Rest assure that it is safe either way and doesnt have much impact on high speed systems.

Let me know if any further clarification is required.

Good Luck!
Dont forget to appreciate the solution if I could have been of any help!

tuneup utilities says that prefetch data deleted, but when i explore the hard disk i find it i suffer from slow startup windows 7... i tried everything but still slow


Hi,

This is expected.

1. Turn off the option to clean the Prefetch in Tune-Up Utilities

2. Windows will just need to re-create all the prefetch files again, thereby slowing down Windows during boot and program starts until all the new prefetch files are created

Hi,

It might be due to Virus.So please use a anti-virus software and try scanning the virus

To my knowledge , if you have just updated , you should be OK , MS say they have have fixed all their faulty patches .

Did you download all the security fixes ?

Here are some other things to try .

If your system hangs about 2 or 3 minutes at startup, where you can't access the Start button or the Taskbar, it may be due to one specific service (Background Intelligent Transfer) running in the background. Microsoft put out a patch for this but it didn't work for me. Here's what you do:

Click on Start, Control Panel, Administrative Tools then Services.
Go to the 'Services' tab, find the 'Background Intelligent Transfer' service.
Disable it, apply the changes & reboot.

Or if you don't want to disable it .

Background Intelligent Transfer Service. Uses idle network bandwidth to transfer data. For the majority of Users this feature should be of little use & as such I'd recommend setting it to Manual. Those on highly active Networks may benefit from having this set to Automatic, although it may be worth testing out to see if it does.

• Defragment boot files
The boot defragment option is usually enabled by default, but it may be disabled, or not properly enabled. If it's not working, XP may boot dog-slow.
To enable it:
- Edit HKLM\Software\Microsoft\Dfrg\BootOptimizeFunction, find the string called Enable. If the string value is set to N, change it to Y.

Enable Quick post in BIOS setup , as long as you have a have a lot of memory .
The normal memory test , is tested three times & that alone may take 60 to 90 seconds.

Disable the Windows XP Prefetcher
Windows XP has a Prefetcher component, which shortens the amount of time it takes to start
Windows and programs. When trouble shooting either Windows or program start-up issues, it might
be helpful to disable the prefetcher, because it runs as a background service while other
applications are running or loading.

To disable the prefetcher:

Start the Registry Editor
Go to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ SessionManager \ Memory Management \ PrefetchParameters
Double-click the EnablePrefetcher value (remember the value that EnablePrefetcher is set to!)
Change the Value data to 0 to disable the prefetcher .
Close the registry editor and reboot the computer for the changes to take effect
When done troubleshooting, you can re-enable the prefetcher by changing the Value data to its
original value.

Values for EnablePrefetcher are:

0 - no prefetch
1 - prefetch applications only
2 - prefetch boot only
3 - prefetch both applications & boot (default)
I find 5 is best .

THANKS......
WITH REGARDS........

Probably I've solved the problem.
You have to work on Windows Prefetch.
Download Windows XP Prefetch Clean and Control (from www.majorgeeks.com/download2495.html).
Launch this program.
Select the option "Clean Prefetch Folder Now" and "Monitor boot file launch only (Recommended)". Then select the buttons "Set Prefetch Parameters" and "Exit".
Restart your pc.
