Windows 7: HELP NEEDED! Win7 DWM.EXE issues upon install any m$ rollup of 2018

11 Aug 2018   #31

Windows 7 Ultimate x86

Perhaps I am also affected by the hot summer here. I will try again after the hot days are over. In any case I agree with you that this solution solves the DMW crashes !

I suspect that some ugly and CPU demanding code has been introduced to solve the spectre and meltdown security breaches. But I also strongly feel that these fixes ought to be done in the CPU hardware, not in the kernel software.

I am also convinced that there are more such 'hardware' security leaks coming. Spectre and meltdown are just 2 of many to follow. These are hardware design problems. Not software design issues.

I wonder how MS is going to cope with that in the future.

well, well, well... there are some progress from m$ in Aug 2018 Rollup

due to some acknowledged mess with AMD CPUs m$ updated its both win7 integrated CPU drivers intelppm.sys & Processr.sys from v6.1.7600.16385 to v6.1.7601.24214. however more changes seem done into Processr.sys and now if you change your Intel CPU driver from its default intelppm.sys to Processr.sys then there are no more dwm.exe issues...

actually the trick is a simple one:

1) change the CPU driver thru device manger driver update to the 2nd listed as Processr.sys and it will keep your CPU frequency at its max specified value by itself; or
2) you can still use the default Intel CPU driver intelppm.sys but is such case you must keep a multiplier of your CPU frequency at its maximum, and you can easily do it thru a laptop power plan advanced settings by changing min state of CPU from its default 5% to 100% or do actually same by use of Core Parking utility as above - to move a slider for frequency to the right from default 5% to 100%.

that's all.

p.s. basically your don't need that Core Parking utility anymore. however if/when you'll remove it pls don't forget to return its CPU parking value set manually to its default value as 10% (at least 10% was default in my case of 2 laptops + 1 desktop)

p.p.s report results here.

Interesting indeed ! Thanks for this info. It will take some time before I will be able to test it. Please bear with me.

If there is some delay with your testing than you'd better start right from install Preview Aug2018

The CPU drivers there are same but it includes IE11 update v11.0.76 that is not offered separately.

Understand, OK, will do that. I also need to test the crashes of the NVidia driver. Even with Dec 2017 level I have occasional crashes with the NVidia driver. Don't know exactly when this started, I guess about 1 year ago or so. Before that I certainly NEVER had driver crashes not from any driver version of NVidia. This spooky business just started some point of time in the not too distant past.

Thanks a lot for the troubleshooting!

Hi guys,

Hereís a message from the Netherlands (so forgive me my bad English!).

Beside my own 4 computers, I do maintenance for some 16 computers from friends and family, almost all still running on Windows 7.

Starting end January, three of these suffered from the DWM-problem (black screen, 9020 error in application logging). I did lots of analyse, including for graphical drivers, but couldnít find a solution; I rather soon suspected M$-updates frombeing the main course.

These three computers were/are of exactly the same type: Dell Latitude D830 (refurbished,very good quality) with Windows 7 Pro.
First it was very hard to find info on this issue on the internet, only a German guy with a D930 reported the same errors.

So I was very pleased when I found this post some months ago!

Last month I rolled back all 2018 updates on one PC, as expected the DWM-errors stopped, but we can agree itís not a perfect solution.
Last week I tried changing the processor minimal to 100% on an other PC. The user for this machine suffered at least 6 times a day from a black screen, but after changing the value all runs completely smoothly (Iíve been monitoring it for a week now)!

So this is a (very) long story to tell you: THANKS A MILLION TIMES!

well, now you can enjoy September 11, 2018—KB4457144 (Monthly Rollup) that includes IE11 v11.0.85 OR September 11, 2018—KB4457145 (Security-only update) on absolutely same prerequisite condition - CPU Min state must be set to 100% instead of its default value as 5%, which is equal to setting of its frequency to 100% or a frequency multiplier to Max.

however, all this jazz is clearly the problem of m$ rollups 2018 and m$ yet did nothing to resolve this issue thru 9 months of 2018 almost passed by...

thus, shall I end up this my brief summary as usual - F*CKKKKKK M$!

UPDATE: it has been tested that 50% as min cpu state seems enough to be on safe side concerning dwm.exe crashes... if it matters after all...

although maybe it's worth to mention here that:

I'm still using win7 pagefile size as Recommended i.e. the visible by win7 RAM x 1.5

and the Spectre-Meltdown protection win7 registry keys as:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]

on all of my win7 machines under testing.


P.S. m$ has updated both win7 integrated CPU drivers as above twice thru Sep2018:

Sep 2018 full rollup - up from V6.1.7601.24214 to V6.1.7601.24231
Sep 2018 Preview - up from V6.1.7601.24231 to V6.1.7601.24236

but the dwm.exe issues tested as remaining unresolved if CPU Min state is set to default 5%!

Am back to testing here. I just installed the 10-2018 October roll-up. I did not do anything yet, like change the CPU driver or the power plan. Also did not install the Core Parking utility. Everything plain default Windows + updates.

After just a few minutes the first DWN 9020 crash. I now changed the Min CPU setting to 50 % as mentioned by you in the update. Let's wait and I will report back.

Can you, please, expand a little on the Spectre-Meltdown registry settings, Which value effects what patch ?

Update: Nope, 50 % is not enough. Increasing to 100%

It seems that 60% is enough in my case. It makes a difference of 1 step in the Intel SpeedStep routine. My CPU is 2 GHz with turbo of 2.2 GHz. 50% selects 1.2 GHz, while 60% raises the minimum frequency to 1.6 GHz.

If I encounter a further DWM crash also at 60% I will report it here.

Still I consider this fix a dirty trick. It completely defies the Intel SpeedStep technology. My fan is now almost always on.
