I am new here so please forgive my mistakes —
I have two computers at home – my own and my wife’s Dell Inspiron 15R 5520 laptop. I addition to these I look after six computers where I do two days a week voluntaty work. All computers have i5 processors (Haswell, Ivy bridge, or Sandy Bridge processors).
All updates done up to end of December 2017.
Windows Updates turned off —
Image of computers done with Macrium Reflect as of end of December.
Allow Reg key has also been installed by Avast antivirus on all machines.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The following are my notes for each month as I have been following the updates debacle.
Note — the six machines I maintain as a volunteer all have fixed IP addresses set in each machine so the whole network is effected by the March Updates.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
JANUARY UPDATES
KB4056894 — For Meltdown and Spectre vunerabilities
Causes slowing of computer
(my wife’s laptop took 8 times longer to start with this update)
Some computers will not do a restart but have to be forced restarted — Pre haswell cpu’s suspected
Does not solve Spectre problem
Update Hidden
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
FEBRUARY UPDATES
KB4074598
For Meltdown and Spectre vunerabilities
Some computers will not do a restart but have to be forced restart — Pre haswell cpu’s suspected with Sandy Bridge and Ivy Bridge CPU computers at QMBC
Does not solve Spectre problem
Update Hidden
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MARCH UPDATES
KB4088875 — Breaks Fixed IP addresses — Suddenly withdrawn
KB4088881 offered on 25th March
Info from MS says it breaks Fixed IP addresses on network
KB 4099950 — offered on 31st March as an optional update — Appears to be a fix for broken network IP addresses caused in KB4088875
Neither of these have been installed
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
APRIL UPDATES
KB 4099950 offered on 5th April as an Important update this time
Appears to be a fix for the breaking of Fixed IP network addresses but later than the March KB 4099950
KB 4093118 – April Quality rollup – offered as an important update on 12th April
Many fixes including breaking of network fixed IP addresses (so maybe we do not have to install KB 4099950 but it is still offered )
KB 4093118 – Reportedly keeps presenting itself for installation in an endless loop.
KB 4056894 — January update and KB 4074598 — February update
Have disappeared from “Hidden updates” where I put them
Neither of these have been installed
18th April
KB 4099950, (the abandoned patch for fixing the NIC/static IP bug in Win7) was removed and not offered for update again
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A question – Can the Allow Reg Key be removed from the registry? This would stop the Meltdown / Spectre updates from being installed — I think. As there are no “In the wild” instances of these two vulnerabilities and the motherboard manufacturers are not likely to update the old motherboards, I wonder if this a reasonable way to go.
Any advice / comments as to what to do in the current circumstances would be appreciated.
