I am currently unable to uninstall the "KB302477" update because it's not included within the list of installed updates within the "Windows Update" panel (this issue is restated within the below attached link). The attached link was published by InfoWorld on Monday 12/15/14 in regards to this update. As you will conclude after reading it, it sounds like there is a little bit of confusion going on within the Microsoft support side of the fence in regards to this update. This update may have nothing to do with the power shell problem but it may be causing other problems that you are currently experiencing. http://www.infoworld.com/article/2859267/operating-systems/windows-7-hit-by-rash-of-bogus-not-genuine-reports-validation-code-0x8004fe21.html

I began receiving "Power Shell Has Stopped Working" messages on Saturday 12/13/2014. I am running Windows 7 at a Service Pack One Level and I have automatic download and updating enabled within Microsoft's "Windows Update" utility so that the software is always kept updated with the latest fixes. On Friday 12/12/2014, an update was successfully applied (it was the only update applied on that day) and then the Power Shell problems began on the very next day. I ran full system scans with both Norton and Windows Defender and no issues were found. I keep both of these products updated with the latest virus definitions at all times. I'm currently investigating the possibility that this is not a malware related problem but rather a problem update distributed by Microsoft to the user community. It would not be the first time that I've encountered problems that were caused by Microsoft's fixes. The description and id for this update is "Update For Windows 7" and "KB302477" respectively. If you're on automatic updating (like I am)and currently running Windows 7, then there is a strong possibility that this update was also recently applied to your system. If so, please provide some feedback that this situation is also in existence on your end.
