Hi, I hope I am not off-topic here... I have a strange issue clearly due to Windows Update on my Lenovo Y700 PC running Win10 home. Since the cumulative security update of May 2023, my Y700 has became totally unstable, it crashes with a BSOD in a repeatable way, when copying files for instances. The only fix so far is to uninstall the security update (the May one is KB5026361, the last one is KB5027215). The trouble is that it is pushed again after a few hours so I also have to block updates. With Windows 10 Home it is not possible to block or pick up which updates are to be installed. My current workaround is to let the update install, then reboot, then block for 4 weeks the updates then uninstall the latest update and reboot. And do this every month. As soon as the update is uninstalled, the PC is stable again. When I "look" at the BSOD dump file with Nirsoft BlueScreenView, it says fltmgr.sys driver was part of the BSOD. But other people who examined the dump don't arrive to the same conclusion and only speak about memory corruption possibly due to a driver. Any hint on how to solve this ? Blocking the updates is not a good idea in general... Thanks ! Sincerely, Merle1
@MerleOne The only recommendation is that you should first clean your computer properly, then install the correct and up-to-date drivers, and only update a completely clean and bugsfree computer from now on. In this case, it is very clear that you have been using an unmaintained and unmaintained computer on a regular basis. It's also quite clear that these updates, and especially the Windows Defender updates, never cause any of the problems you mentioned. Start by cleaning your computer and updating your drivers, but it must be assumed that the OS installed on your computer itself is 100% in order. If computer maintenance is a problem for you personally, you should seek the help of experts/specialists. It is necessary to maintain the computer not every day, but every minute, i.e. all the time.
3 things comes to mind: I have only good experiences with - Who Crasched, it always finds the right offending driver. You can install Sordums - Windows update blocker, and stop it permanently, and then install a free Av instead. Since W.update is totally stopped. According to my experience a fresh install usually solves this type of problem.
Hi @kaljukass, Thanks for your advice ! Regarding drivers, I have updated almost all proposed by Lenovo for my Y700. Even if they have no apparent link with filesystem management. I am not sure of what you mean by "clean computer". Do you mean using something like CCleaner ? Like using DISM & Sfc/Scannow : already done on a regular basis. Please note that as soon as you start installing third party software, which is IMHO the main purpose of Windows, you start creating potential issues. Just to give an example : with the same computer, several years ago, I installed DriveCrypt from SecureStar to create secure containers from this PC. Several months after that, I started to notice BSODs simply when physically removing an USB flashkey after it was logically ejected. I tracked the issue as being linked to a DriveCrypt driver. I was able do deactivate that driver at boot and since then no BSOD when ejecting USB flashkeys. So whatever the maintenance you give, you are always at the mercy of an incompatibility of a third party software. There also something I have not tried yet : using the manual Windows 10 download tool https://www.microsoft.com/fr-fr/software-download/windows10 and clicking on udpate now, I found on other Win10 PC it helped solve many issues at once and provide with the latest version. Sincerely,
Hi @pb1 Thanks for your reply. I already used the free version of WhoCrashed from Resplendance Software but it just mention memory corruption probably due to a driver. I have not trialed the commercial version, there is no eval version of this supposedly more complete dump analyzer. Do you recommend it ? Good to know about Sordums' Windows Update Blocker, will check it. The main drawback is that, after a while, some authentication certificates get expired and some connections will not work any longer, I saw that on old Win7 versions and XP even more. But this may be a nice option. Regarding a fresh install, if that means erasing all programs & configuration, this would really hurt... Really a after last resort solution. Many thanks,
I based my statement on use of the free version. So more then so i do not know. If certificates is a problem you need to have W.update going i suppose, then use Wumt instead. With it you can hide those updates. Wumt: https://www.majorgeeks.com/files/details/windows_update_minitool.html Wau manager is another tool. More info about these 2 is on the net.
Yes, Wumt seems very nice, I'll look into it, thanks again ! I have posted more or less the same issue on a Lenovo & Microsoft forum. People were helpful there too but this is closer here to what I need. Thanks a lot Regards,
Yes this type of programs is what you need, i should have thought about it immediatly. The following, that Ms withdrew, you probably remember from W7: https://www.majorgeeks.com/files/details/microsoft_show_or_hide_updates_troubleshooter.html
c:\windows\minidump copy at least the 3 latest dumps to desktop, then zip it, attach. for a proper view to crash dumps there is nothing better than windbg from Windows SDK 10 https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/ (the installer is an online installer, but have granular settings, i prefer to have it all -> iso) and its FREE! fltmgr.sys is responsible for a lot of filtering events in windows, at least all crashes are due malformed drivers, or other security software - in short: all were external impacts, not from windows itself. lenovo software can cause this also. forget it, its a dumb software. it only reads the causing file, but not the stack with the faulting code. one to mention - its not clever to prevent updates, in special, when security is that much concerned like the named KB. i have both installed on all machines, one in march, the other mid june, no issues. i dont use ccleaner, i dont use other cleaners, i use defender, no other security software except a secondary firewall. either your win10 is damaged somehow -> DISM, or some other software/driver is interfering.
Is it possible that the bsod is caused by drivers that installs at the same time as the updates, if so, maybe the updates is ok, the drivers not. Then disable the driver update in Windows.
Of course, it would be nice if Microsoft could do at least something properly, but unfortunately it remains only a dream. In the same way, it will probably remain a dream that all people start knowing how to use what they have. But you should remember that BSOD is not caused by any update, but by something not working or matching. Well, I'm probably in the wrong environment and it's time to leave. Sorry for suggesting you take a little care of your system and your soul.
Hi, Good news, as of today, with the latest Win10 security update (KB5031356), the issue is no longer present ! I couldn't reproduce the crash/BSOD. No idea why this is solved now, formerly I had to block the updates for 5 weeks (the max available), then accept them, then block them again, then uninstall the latest cumulative security update. Hopefully this will not return but only time will tell ! Thanks all for your replies ! Best regards,
