Windows 8.1 Cannot Install Updates

JM44 · Oct 9, 2016

Hey everyone,

I'm usually not one to post but I'm totally out of my depth on this one. Yesterday I tried to update my .NET 4.5.1 framework to the latest version, but the installer would either hang for 4+ hours or else return an illegal character error. I tried to remedy this via Windows Update, but Update fails with Error Code 80070246. SFC /scannow fails with Windows Resource Protection could not perform the requested operation, even after verifying that PendingDeletes and PendingRenames exist. I attempted a system refresh, but that failed as well, and no changes were made. I've run DISM StartComponentCleanup and RestoreHealth, both fail with Error: 582 an illegal character was encountered. I'm clueless with how to proceed. Any help would be appreciated.

Thanks!
