There are hundreds if not thousands of hits on that issue. I found a windows update diagnostic tool from Microsoft that fixed it on a Win7 machine a customer gave me to use. I needed PoSH V3 on that VM and that updates issue was a royal PITA.

My work PC got corrupted, and I got a new hard drive of our WIn 7 SP1 image. And I'm trying to install RSAT on it, and it seems to just be hanging on "Searching for updates on this computer". Looking into WindowsUpdate.log I see this: 7756 1dcc Misc =========== Logging initialized (build: 7.6.7600.320, tz: -0500) =========== 7756 1dcc Misc = Process: C:\Windows\system32\wusa.exe 7756 1dcc Misc = Module: C:\Windows\system32\wuapi.dll 7756 1dcc COMAPI ----------- COMAPI: IUpdateServiceManager::AddScanPackageService ----------- 7756 1dcc COMAPI - ServiceName = Windows Update Standalone Installer 7756 1dcc COMAPI - ScanFileLocation = C:\5801e7aa26267eca7c\wsusscan.cab 1152 a74 Misc Validating signature for C:\Windows\SoftwareDistribution\ScanFile\f9550e7e-d05e-4ef0-9643-29723ef36353\Source.cab with dwProvFlags 0x00000080: 1152 a74 Misc Microsoft signed: Yes 1152 a74 DtaStor Default service for AU is {7971F918-A847-4430-9279-4A52D1EFE18D} 7756 1dcc COMAPI - Added scan package service, ServiceID = {F9550E7E-D05E-4EF0-9643-29723EF36353} Third party service 7756 1dcc COMAPI ------------- 7756 1dcc COMAPI -- START -- COMAPI: Search [ClientId = wusa] 7756 1dcc COMAPI --------- 7756 1dcc COMAPI <<-- SUBMITTED -- COMAPI: Search [ClientId = wusa] And now it's just sitting there. I see nothing in the Event log. Any ideas? The image shows last Windows Update was April 2015 (don't say anything, I have nothing to do with workstation imaging). I did install the April 2015 Servicing Stack Update, and updated from IE10 to IE11 (successfully). Ideas? I'll be off for the New Year's holiday, so I won't be able to really do anything about it for a few days, but any ideas for when I get back? (saw the same issue when I tried to update my Powershell v2; just sat there at "searching for updates"). Thanks
