The June update fixed the slow update searching in Windows 7 https://support.microsoft.com/en-us/kb/3161608
Its just bad coding from Microsoft of not clearing out superceded packages. If you left it for 2 or 3 days it would likely finish, but that update should help you out. Here is the copy and paste from Susan Bradley’s patch grid worksheet on the subject If you are experiencing Windows 7 update scan slowness you are not alone. There is no fast fix for this and the underlying problem is Microsoft's lack of pruning of superceded patches. Here is the recommended order of patches to install at this time if you are building a new 7 at this time or rebuilding one.

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").
