Extremely Slow Boot Caused By Datastore, How To Fix Issues With Datastore

When the system boots up it spends a ton of time reading and writing to the DataStore.edb file which is located in WindowsSoftwareDistributionDataStore directory. This makes the system run really slow for several minutes, probably about 10 if I”m honest. If you stop the Windows Update service, within a minute the system will stop reading and writing from the file and everything runs smoothly.

Things I”ve tried:

I”ve stopped Windows Update, deleted the file, rebooted, but when I do that Windows rebuilds the file until it”s a few hundred MB in size. Once Windows is happy with whatever it”s doing, it stops and my disk usage and cue drop down to normal levels and the system does whatever you want with plenty of speed.

I”ve booted into SafeMode and run several virus scans and Kaspersky”s RootKit killer tool and nobody finds anything offensive.

What should I try next?

I know it”s way past the point of being able to provide a suitable solution for you now, but I have exactly the same thing with a Windows 7 machine at work. For future reference, you can always kiểm tra the integrity of (/g) and/or defrag (/d) *.edb files with esentutl.exe.

e.g. esentutl.exe /d c:WindowsSoftwareDistributionDataStoreDataStore.edb

If you are unable to run this command with “-1032” error, you can boot into safemode (without networking) and run the command from there. You might first need to run it with the /p switch to repair file corruption.

RAMMap showed that C:WindowsSoftwareDistributionDataStoreDataStore.edb mapped file was wasting 400 Mb of my precious RAM.Moreover Windows Update was constantly slowing down the system in process of updating that huge file.

esentutl.exe just reduced DataStore.edb size from slightly more than 600 Mb to slightly less that 600 MB and proved to be useless in my case.

http://juneyourtech.blogspot.com/2013/06/datastoreedb-and-windows-vista.html states that deleting this file is also not an option as Windows Update would rebuild it to the same size of next run.

So I had to completely disable Windows Update Service autorun. This greatly lowered waste of RAM, CPU and disk IO. The system is much more responsive now.

Expanding upon
mafbailey “s answer (And a big thanks to you, as well!) make sure to open the command prompt as an administrator when utilizing the following command line action to have the appropriate file permissions.

I”d have been stuck had I not known =)

esentutl.exe /d c:WindowsSoftwareDistributionDataStoreDataStore.edb

I have experienced the same problem with a slowly starting computer running w7 home edition. Opening email or firefox was frustrating.

On my computer, during start up, the anti virus program (windows essentials) seemed to be taking a lot of time on the datastore.edb file.

This link about“Improve PC Performance and Stability by Properly Configuring Anti-Virus” solved the slow start up problem for me.

The solution basically involves telling the virus scanner (windows essentials) to exclude checking this file. I did the other exclusions on the windows files as well. (but i”m fine with the scanners checking my photos, even though they should be safe)

Try installing Windows Update KB3050265, released 2nd June 2015.

This is optional so you may have to look for it in Control Panel > System and Security > Windows Update > Show all available updates > Optional, and manually install it.

Microsoft released a new WindowsUpdate Client Update to fix the slow Update searching/Installation.

Installing and searching for updates is slow and high CPU usage occurs in Windows 7https://tư vấn.microsoft.com/en-us/kb/3102810

Tải về:32Bit: http://www.microsoft.com/downloads/details.aspx?FamilyId=fcd6bf5d-f004-4ca3-aa7e-1de462b91dd0

64Bit: http://www.microsoft.com/downloads/details.aspx?FamilyId=4fe566bd-31b1-4413-8c4c-412b52533669

This updates reduces the detection time and uses less RAM. So try it out

I don”t know why this says that I posted this in January 2013, this problem was only a few months ago in 2015. Ha!

Anyway – I”m sorry to waste everyone”s time. For some reason I wasn”t getting notifications about this thread until today, December 9, 2015.

I tried a number of things and ended up on the phone with the manufacturer of the device that this computer was within. It turns out that they have a bug in their implementation of Windows that causes this to happen. The only solution to the problem is to re-image the machine and hope it doesn”t happen again.

This applies to Zeiss OCT machines for those who are wondering.
