Windows 7: Need help in removing a windows update

Need help in removing a windows update

After installing a "intel systems driver" update, i am no longer able to downclock my CPU by reducing its multipliers.

Windows: optional update ‘Intel – System – 6/28/2016’ | Born's Tech and Windows World

That's the update, and apparently it is some kind of BIOS control thing? I need to uninstall it, but I cannot find it in the list of installed programs or updates. There is no system restore point before the update.

Unfortunately there is no KB listed for this update as it is an optional intel system driver update.

Hi Q2,
That just leaves the long route. bummer

Go to device manager view >> show hidden devices
Work your way thru the list of all intel drivers
They will show an install date
when you find it/them, (could be more than one)
select the roll back option

OR
post a copy of the days CBS log when the driver was installed MIGHT give me pci/ven no

Unfortunately show hidden devices in device manager shows me no intel stuff at all (at least, not ones with the word intel in the name).

Where can i find that CBS log?

Does this help at all? Its the info on the microsoft update catalog : Microsoft Update Catalog

C >> windows >> logs >> cbs then open the text folder click on edit (top left) then find, in the small box that opens type pci -- copy paste the entry.

Well the CBS log for yesterday is archived, i can extract the .log file but it is MASSIVE, 600+ MB large and all my text editors are refusing to open it.

Any idea on how to open it?

Hi Q2,
I dont know of any reader (notepad word etc) that can cope with that much data.

Not sure if a restore would be of any help, it does list programs affected not sure about drivers.

Best i can suggest was my comment re ACPI..

What do you mean by ACPI?

I dont know if you can download the drivers from the microsoft update catalog link above, but it includes a .INF file that says that it modifies the BIOS. Which would explain why i am no longer able to decrease my CPU multipliers.
