Fix Spooler SubSystem App has stopped working

After I have installed windows 7, my computer get the following message on each startup time:

Spooler subsystem app has encountered a problem and needs to close
Spooler SubSystem App has stopped working

I think that maybe you need to update your Windows 7 version. Because the problem seems to be resolved since updated to 7048 version.

Or you can try to fix the error by this way:

1. Click the start button --> Control Panel --> programs and features --> windows features.
2. Then find the "Printing and Document Services" in windows features. Untick "Windows Fax and Scan" and "Internet Printing client".
3. Click the OK button to apply and reboot your PC.
4. When login the Windows, system will find the printer and install the priter driver.
