datastore\datastore.edb
I'm using Vista but googling has shown the exact same problem is found
in win7. The relevant file exists in XP, but I don't know if the problem does or not. AFAIC, I've solved the problem, so this is just to share with you. The solution was simply to turn off automatic Windows Update. Vista is getting few or no updates these days. Not sure about 7, but there is manual update. Now that I'm using Windows Resource Monitor to watch my disk usage, I've noticed that I was creating Previous Versions. I stopped that and things seem faster now. So that's good. This morning, I needed to write and send one short email and then leave within an hour. Sounds like plenty of time, except the harddrive light was on constantly for at least an hour, and I could barely type a single character in the email program. (I think this has happened other mornings, but this time I was in a hurry.) It was reading (and maybe writing) C:\windows\SoftwareDistribution\datastore\datastor e.edb It ranged from 20 to 45MB/minute. I forgot to note CPU usage. When I got back 3 hours later, at least by then, that stage was over. I used, for the first time in Vista, the built-in WinVista search to search for the file, and searched everythwere, and I'd heard that the search was slow, but it did NOT even find the file!!!! (I tried again giving the fully qualified name, and it still didnt' find it, even though it's there and it's not a hidden or system file. How can that be?) So I used Search Everywhere and it quickly found it. 528K, updated 2 hours ago. (I also dl'd RAMmap, from Sysinternals, because one webpage mentioned it. It didn't really help me but it's free and interesting. https://technet.microsoft.com/en-us/...ls/rammap.aspx ) (I also used esentutl.exe /g c:\Windows\SoftwareDistribution\DataStore\DataStor e.edb in administrative mode to check the files integrity. I don't know why that was recommended but it passed. ) So what's the solution. Suggestions from other people: http://superuser.com/questions/53941...-computer-down PC Boots then writes giant datastore.edb file slowing the computer down. " If you stop the Windows Update service, within a minute the system will stop reading and writing from the file and everything runs smoothly. " But if you read further, apparently that's not enough for him. I hope it's enough for me. The service is called wuauserv but I didn't stop it directly. Another one says: "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." AFAICT windows update for Vista has stopped updating. In the last two weeks I've only gotten one new "Check for selected Malware file". I don't know if that means there is no point to disabling it, or if it's still wasting cycles and there is no reason not to disable it." ******************** However, I turned off Windows Updates and I havent' had the problem this post is about since then. I can always check for updates manually when it won't interfere with my compute use. ********************** Another guy said "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. .....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)" I didn't think AVG scanned files on startup, and it listed under "Image" svchost (netsvcs), not AVG , but I'll wait until this happens again and see if AVG is using appreciable CPU. (I think I've fixed it so it won't happen again.) Another guy said "Microsoft released a new WindowsUpdate Client Update to fix the slow Update searching/Installation." but it's only for 7 and Server 2008. https://www.reddit.com/r/pcmasterrac...storeedb_help/ "Every day it ramps up my disk usage to 100% which pretty much kills anything I want to do. It lasts from 5 min to an hour or two depending on how long my machine has been off for previously (The longer its been off, the longer the disk disruption and usage lasts) although it will happen every day even if the machine is never shut down. Finally the original poster said there was something wrong with the original implementation: "This applies to Zeiss OCT machines" but the problem is more widespread." I don't even know what Zeiss OCT is! Another guy complains more about it using RAM and the webpage guy says: Can you please zip/attach your c:\windows\windowsupdate.log file? If it's too big to attach, please upload to SendSpace and just provide me the link. Finally told him to do a repair install! (I don't think so!) https://www.sysnative.com/forums/win...gging-ram.html |
