Skip restarting during SQL Server installation
While ago I had similar issue while installing SQL Server. And I used a registry hack to avoid restarting windows machine. Just be aware that it could lead to unforeseen issues later on. Do following steps,
Fire Regedit.exe application in Windows.
Go to, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager , and instead of “EXPANDING” Session Manager, “SELECT” it and you will see the entry called, PENDING FILE RENAME OPERATION.
Take backup of registry value first.
Then, If PENDING FILE RENAME OPERATION has any values just remove it and clear the value.
Reboot the System and again go to PENDING FILE RENAME OPERATION and see if there is any values still available.
If no value is there then simply fire the installation process.
If any value is still present then simply remove that value and without restarting fire the installation process.
