I'm using Windows 7 evalbuild 7100. Instant search is no longer working and when trying to start windows search service I get the following errors:1:Faulting application name: SearchIndexer.exe, version: 7.0.7100.0, time stamp: 0x49ee9f20Faulting module name: ESENT.dll, version: 6.1.7100.0, time stamp: 0x49eeaa59Exception code: 0xc0000005Fault offset: 0x00000000000b1eccFaulting process id: 0x1350Faulting application start time: 0x01ca24e0afb2b1f8Faulting application path: C:\Windows\system32\SearchIndexer.exeFaulting module path: C:\Windows\system32\ESENT.dllReport Id: ee0070dd-90d3-11de-9bb9-001d09d2465d2:Fault bucket , type 0Event Name: APPCRASHResponse: Not availableCab Id: 0 Problem signature:P1: SearchIndexer.exeP2: 7.0.7100.0P3: 49ee9f20P4: ESENT.dllP5: 6.1.7100.0P6: 49eeaa59P7: c0000005P8: 00000000000b1eccP9: P10: Attached files: These files may be available here:C:\ProgramData\Microsoft\Windows\WER\ReportQueue\AppCrash_SearchIndexer.ex_bdebc2359b1574dbddc283f48bb783db45f62b5d_0ca13b2e Analysis symbol: Rechecking for solution: 0Report Id: ee0070dd-90d3-11de-9bb9-001d09d2465dReport Status: 4http://technicallead.wordpress.com/

The error message has determined the root cause is ESENT.dll. You have three methods to solve this issue: 1: Copy the C:\Windows\system32\ESENT.dll and C:\Windows\system32\SearchIndexer.exe from a working fine computer, and then replace them on your computer in the same folder. 2: System File Checker (SFC) a. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. b. Type the following command, and then press ENTER: sfc /scannow The sfc /scannow command scans all system files and will recover the corrupted ones. 3: System restore. Use the system restore back up the system to a state before this issue occurred

I know it's late, but thanks for this. I ended up rerolling Windows 7 to get all of it to work.http://technicallead.wordpress.com/
