I followed through some of your threads to see if i could figure out your patterns of fixing corrupted registry files that deal with windows update. I have both SFCFix.exe and Windows Update Rediness Tool installed. Here is the current error i receive from the CheckSUR.persist.log. Checking System Update Readiness. Binary Version 6.1.7601.22471 Package Version 25.0 2014-06-26 14:00 Checking Windows Servicing Packages Checking Package Manifests and Catalogs Checking Package Watchlist Checking Component Watchlist Checking Packages Checking Component Store (f) CSI Mismatched Identity 0x00000000 appid microsoft.vc80.atl_1fc8b3b9a1e18e3b_8.0.50727.4053_8a1a02152edb659b appid and keyform do not match; appid is wrong. Summary: Seconds executed: 955 Found 1 errors CSI Mismatched Identity Total count: 1 Click to expand... I found the registry keys related to "microsoft.vc80.atl_1fc8b3b9a1e18e3b_8.0.50727.4053_8a1a02152edb659b", it was missing before... so i copied it from a Win7 system that had that registry key. However, now i am receiving an appid error as shown above. I realize that something is wrong in the HKEY_LOCAL_MACHINE\COMPONENTS\ area... but i don't know how exactly to fix this precise problem. Can you please give me some pointers on how to fix this? Original problem is that i cannot install IE10 on a Win7 64 bit machine. I also have this same issue on Server 2008 R2 machine. I am thinking corruption is definitely the problem here. Repair install on the Windows Server 2008 R2 machine is a very last resort for me. Thanks!
