KB2670838 is such a PITA. I've applied it on Acer Aspire AX3810 which is up to date with gfx drivers & windows updates. Since installing the patch, it has given me nothing but problems. Although no single process hogs resources after the update, the system is sluggish in general and opening any Windows utilities such as task manager, services, etc or 3rd party programmes makes the computer hang. When I eventually get to open task manager, it shows normal CPU usage.
When booting the system after the patch, sidebar.exe usage was fluctuating and after killing it, the sluggishness disappeared then then another issue. When viewing certain sites, the text appears to be blurry when viewed in Firefox. Turning off 'Use hardware acceleration when available' in Firefox fixes this issue but what bugs me this option has always been enabled and I've never had the text blurring issue until after the patch.
I've uninstalled the patch and sidebar now loads fine like it always has. I use a few gadgets such as the default clock/calendar as well as 2 3rd party gadgets CPU Usage & Network Meter. Has anyone else experienced similar reliability issues with this patch and any advice on how to troubleshoot this?
