sql2008 when installing prompts to restart the computer failed workaround

When you install SQL 2008, one of the items in the detection installation environment is "Restart the computer" and the result is "failed." Read the internet for half a day, found a solution, although I did not understand the specific reasons, but the problem is solved, the solution is as follows:
First, windows+r, enter "regedit" in the dialog box, click Run;
Second, this will pop up the registry information, found in the "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager" directory
Third, delete the "PendingFileRenameOperations";
Close the dialog box and restart the installation of SQL Server2008 for problem resolution.
