Both of the KB articles for this month’s Win7 patches have been updated. KB 4074598, the February Win7 Monthly Rollup, and KB 4074587, the Feb Win7 Security-Only patch, both triigger a bizarre error, “SCARD_E_NO_SERVICE.” The KB articles now say:
The LSM.EXE process and applications that call SCardEstablishContext or SCardReleaseContext may experience a handle leak. Once the leaked handle count reaches a certain threshold, smart card-based operations fail with error "SCARD_E_NO_SERVICE". Confirm the scenario match by reviewing the handle counts for LSM.EXE and the calling processes in the process tab of Task Manager or an equivalent application.
Monitor the handle counts for the LSM.EXE process and the calling process before and after installing this update. Restart the operating system that's experiencing the handle leak as required.
Microsoft is working on a resolution and will provide an update in an upcoming release
Which, I’m sure, is comforting news for most Windows 7 customers.
I have already downloaded and installed the Security Only update. The above explanation from Microsoft might as well be in Chinese as far as I and, likely, most Win 7 users are concerned. So I need some advice from some of the members here who might have a clue about this. As I see it I have two options. The first is to uninstall the update completely and then wait until the solution is out. Or, I can leave the patch in place and wait for Microsoft to put out a fix. I have updates set to never check because I do it myself monthly, so knowing when a fix is out is a PITA. I now know to wait even longer before doing future monthly security only updates. (I never do any previews, so I avoided those Feb, bugs.)
Which is the smarter choice, please? And why? Please answer in plain simple English if it involves anything technical. Thanks in advance for any help. Also, am I wrong in thinking that the monthly Security only updates are cumulative so i just deleted the Feb. update and then do the one in March, I will end up OK?
