Applying July’s Patch Tuesday security updates proved a bit rough for some IE and Vista/Win7 Tablet PC users.
In some cases, the solution was to remove the update; in others, it meant installing a patch for the patch.
Internet Explorer patch results in crashes
For most Internet Explorer users, July’s cumulative update (KB 2962872) installed without a hitch. But any browser upgrade can potentially have conflicts or incompatibilities with custom or vertical-market business software. For example, according to a PTC forum post, some of the company’s software wouldn’t work properly after customers installed July’s IE patch. It appears the problem was mostly with IE 10.
Also, a listserve post reported that some ADP clients ran into difficulty viewing the company’s payroll-services site after installing KB 2962872. (Obviously, any delays in processing payrolls is a serious problem.) In both cases, uninstalling the update fixed the issues.
What to do: Browser security updates are always important. But if you’re running an Internet-connected, line-of-business application, test the update before running critical tasks.
Tablet PCs need a hotfix after patching
Among July’s security updates was KB 2973201, a fix for a vulnerability in Windows’ On-Screen Keyboard component. Apparently, Microsoft did not thoroughly test the update on all platforms. After installing the patch on Vista- and Windows 7–based tablets, you could no longer move the Tablet PC Input Panel window either with a stylus or by touch. You could, however, still move the window with a mouse. (It probably came as a surprise to Redmond that anyone was still using a Vista or Win7 tablet.)
KB 2975685 is a hotfix for the immovable Input Panel window problem. As with most hotfixes, this one comes with a warning that hotfixes might need additional testing and thus should be installed only if needed. So far, I heard only reports that the hotfix works and causes no other issues.
