Sql server yüklemesinde bilgisayarı yeniden başlatmanızı isteyebilir ve bu hata bilgisayarı yeniden başlatmanıza rağmen düzelmeyebiliyor, çözüm için aşağıdaki adımları izleyin

This almost worked for me (using Vista) but everytime I rebooted some temporary files kept showing up in my "PendingFileRenameOperations". What did work for me though was
running Regedit, finding the key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager" then deleting the value of "PendingFileRenameOperations".

I then exited regedit, ran my sql server 2k8 express edition setup (without rebooting) and it installed without an issue.

Hope that helps.
