Recent Windows Update KB3064209 causes Windows 7 to not boot

[This thread is now marked SOLVED due to an effective workaround being found that allows Windows 10 to be installed on a system with a G3258 CPU.]

This thread originally addressed the Windows 7 update KB3064209 causing Windows 7 to boot to a black screen, but it was later found that this same coding was unfortunately BUILT-IN to the final release of Windows 10, thus causing anyone with a G3258 CPU to not be able to install Windows 10.

Go to the new posts (they are listed oldest to newest here) at or near the end of this thread to see my post regarding a workaround to this problem.

Original post:

Hi all,

As the title says, Update KB3064209 (Intel microcode update) from a couple of days ago (16June2015) causes my system to fail to boot after it is installed. My Windows version is 7 Ultimate with SP1 and all updates (besides this problem one). The required prerequisites for this update are met.

This update is in the 'Optional' category but if you read the details of the update it seems to be very close to 'Critical'. (Improves the reliability of the processor and Windows may not function correctly without it, it says)

I indeed have an Intel processor, the Intel Pentium G3258 3.20GHz Haswell, sometimes called the 'Anniversary Edition' Pentium.

After I install the KB3064209 Update (I have tried installing through Windows Update and also manually downloading and installing the update) my system will not boot.

It goes through POST then comes to the Starting Windows screen for 1-2 seconds. After 1-2 seconds the screen flashes what appears to be some kind of corrupted graphics for an instant then reboots.

Going through System Restore and restoring to a time before the update causes the system to boot successfully.

Do other people have a problem with this particular update or is it just me?

Obviously, unless I hear that there is a workaround, I'm not going to install it and just hide it in Windows Update.

This is the main reason I have Windows Update set to 'Never check for updates' and I just manually check for them about once a week.

If this was set to automatic and this failure to boot suddenly popped up after a silent Windows Update install in the background , I would probably spend hours trying to find out what caused it.

An installed program suddenly corrupted? A driver problem? Corrupted Windows System files? If so, which one? SFC /scannow is fine but it's not a 'cure all'. I've run it before and it found no problems when I was having major problems and I later found a corrupted system file. It had the right name but wrong size and date. I replaced the file with one from a working Windows 7 system and my problem was fixed.

Any info about others having this particular update causing problems for them would be appreciated.

EDIT:
As I just posted at the end of this thread, WINDOWS 10 WILL NOT INSTALL ON A SYSTEM WITH A PENTIUM G3258 CPU!! (In almost every case) Neither trying the install through 'updates' nor trying the install with an ISO image will work.

The installation fails with this error:
"We couldn't install Windows 10
0xC1900101 - 0x20017
The installation failed in the SAFE_OS phase with an error during boot operations"

As I predicted, this issue has come back to haunt us with a vengeance after most of us here agreed that simply not installing the Update 3064209 was a 'fix' to it causing the headache in Windows 7.

In Windows 10, this is not an 'update' that you can elect to not install, IT'S INTERNAL TO THE WINDOWS 10 CODE!

Microsoft blames Intel, Intel blames Microsoft, and just a very, very few motherboard companies (1 that I know of; Asus) have issued a BIOS update which supposedly fixes this.

A huge amount of discussion in other forums offers two possible workarounds:
1) Removing ALL overclocking of the CPU. (a few people have said this allows a successful Windows 10 install)
OR
2) (And this is just ridiculously unacceptable), going into the UEFI BIOS and disabling one of the cores of the CPU. However, the reports are that 100% of the time, this allows a successful installation of Windows 10.

99% of Pentium G3258 owners who want to install Windows 10, we are screwed.

A lot of reports are that a couple of the Windows 10 Preview versions did not have this problem, but the final 29July2015 release does.

There is a large number of motherboard owners who have somehow gotten the mistaken impression that you're golden if you have a Z series motherboard. Mine is a Z87 and the problem is very real with it. So don't waste your money thinking you can just buy a new Z87/Z97/Z99 and the problem will magically go away, it won't.


Note: I will burn in hell before I disable a CPU core to allow some bull**** 'fix' to a Microsoft/Intel complete and absolute debacle.

I'll guess I'll remain a faithful Win 7 x64 user for some time to come, it looks like.

Same here. When the Windows logo should appear, the system reboots. Safe mode etc. are also not working anymore: reboot after loading CLASSPNP.SYS. System restore to a point in time before installing the latest Windows Updates is the only working fix for me. After getting the system to work again I installed the optional updates 1 by 1 resulting in isolating KB3064209 as the problem. I'm running Windows 7 Professional SP1 x64, fully patched. System runs a Intel I3-4010U @1.70 GHz in a Gigabyte BRIX GB-BXi3-4010.

Hi,

I'd like to just quickly note that where you described the reboot is exactly the same place mine occurs.

1) It displays the 'Starting Windows' screen then reboots at the animated logo that normally shows immediately afterward. In fact, that is the graphic that flashes only for an instant and the graphic appears to be corrupted.

2) When booting in Safe Mode the list of files and drivers continue down until CLASSPNP.SYS, pauses there for a few seconds then reboots and goes into System Repair which automatically uses System Protection to roll back to a System Restore before the KB3064209 install (which then boots successfully to the desktop). I also used a System Restore point manually to achieve the same thing.

The method you used to isolate the problem update was exactly what I did. Luckily it was only trying to update about 6 or 7. I installed one at a time and found that KB3064209 was the bad one.

Hopefully someone who is much smarter than me can give advice on how to install this successfully with a workaround or some type of registry edit or Microsoft Fix It or something.

I'm currently at a loss on how to do it. The problem is that I have a very strong feeling that down the line some update or the other will refuse to install because this one is not installed. If it was just a standalone update that didn't affect anything else, I wouldn't have any problem at all just leaving it as 'hidden' in Windows Update.

Any information will be much appreciated.

Same here: Intel Pentium G3258 on Asrock B85M Pro4, Windows 7 Prof. 64bit SP1.

Unfortunately I had the system restore function disabled and therefore had to format C:

After some testing I also found out that Update KB3064209 is the problem.

Hi SevenDS,

An update: For an unrelated reason, I had to use an Acronis True Image backup to kick my Windows install back a couple of months. It was a pretty bare install at the time of the backup.

All Windows updates and just a small handful of programs (Photoshop, Office 2010, CCleaner, AVG 2015, etc.)

Thinking maybe something was corrupt with the install I was using the other day, I tried updating with the KB3064209 (Intel Microcode update) on the new practically bare install.

Same problem. System wouldn't boot. So evidently it's just simply not going to work with my system, barring someone on SevenForums offering advice for a workaround, registry edit, etc. to make it work.

I wouldn't even be worried about it at all except for the fact that I mentioned in my first post and that is that it's pretty important despite being labelled 'Optional'.

Anyway, just a thought on System Restore that you mentioned.

I've been a computer technician for about 25 years now and I cringe every time I see yet another 'expert' on some website or the other advising to turn the feature off completely.

It has saved me many, many times. When your system fails to boot (a Windows Update that crashes your computer, for example, or a bad device driver or whatever) and it goes into the automatic "Don't worry, I'll fix it for you" mode, it grinds and grinds like it's really working hard to fix the problem for you.

While it does check and attempt to fix a couple of important things, it usually resorts to using a Restore from System Protection to roll things back to when it worked. And most of the time that DOES work.

If a person doesn't like the idea that System Protection's restore points are using up hard drive or SSD real estate, simply set it to something you can live with such as 5% or so.

I've noticed that about 5-10GB (which is tiny these days) works just fine. I normally use about 20GB but that's just for no real reason besides the fact that I install and uninstall a LOT of software and I want many options of when and where I want to restore to when things get crazy.

As you know, when it reaches that limit it simply deletes the oldest restore point and keeps the newest.

Ok, I'm done typing my novel now.

Any help with the KB3064209 Windows Update issue is much appreciated. If 3 people have posted here about that problem, there's at least 100 'lurkers' (vs 'posters') that are waiting and watching this thread because they have the same issue.

Ditto the Win update

Wish I had read this post yesterday.

I just got a Gigabyute i3 up and running as a new station for a user and ready to go home. Now for some unknown reason, I get to the login CTRL-ALT-DEL screen and nothing works. No Keyboard, no mouse. Tried all the Safe modes, Bios disables etc. nothing.

Then I recognized the update KB3064209 and know you guys have the same issue.

Just FYI, it failed to update correctly the first time I tried so I made a manual restore point, tried again with no luck. So after trying to restore, I'm now stuck. It will not even let me have the option.

What can you do without a keyboard, mouse or Safe Mode?!?!?

I hope this thread finds a resolve!!

I also have a g3258 and I'm scared to death right now. Can anyone else reading this confirm that this update works with their g3258? Overclocked to 4.6GHz like mine?

I'm being offered this optional update for intel processors on both my computers despite having an AMD processor on one of them (and an intel processor on the other). I don't currently intend to install it on either computer.

You know it's funny you say that because it's also being offered on my old Asus EEE netbook, that also has an AMD processor in it. Nice logic @Microsoft
