I found an older thread here about Win7 updates to avoid. One of them, KB2670838, I have recently had issues with.
I've had my current laptop since July 2015. I installed a fresh copy of Win 7 x64 at that time and pretty much allowed it to install all "important" updates.
*Just this week* I started having problems with severe memory hogging, apparently by dllhost.exe [COM Surrogate]. That service was using 5-6GB of memory at times. Alternately, FireFox was using up to 5GB of memory while the service was running. Also, simple things like waiting for a folder to display it's contents was taking forever and other severe system lags.
Googling indicated the culprit was update KB2670838, which comes hand in hand with the IE10 or IE11 update. Uninstalling KB2670838 uninstalls IE11 right along with it.
I guess the main question is, why did it wait until this week to start doing this? I've had IE11 on this machine since July.
So, not being 100% sure of this being the problem, I did another fresh install this week, after buying an SSD (which I wanted anyway) and buying 16GB of RAM (also wanted to upgrade from 6GB anyway). The hope here was the HDD or old RAM was the culprit.
No change. As soon as I installed IE11 (so I could run Intel & Dell product and driver ID's from their websites).
I've gone back to IE9 since I only use IE sparingly, for websites (like the two I mentioned) that won't work properly with FireFox.
I've also Googled whether it's necessary to install ALL "important" updates rather than just the latest ones in each category. Any advice on this? I wish there was an SP2 for Win7. That would avoid older bad updates as well as the redundancies.
