You’ve probably encountered unpleasant experience while working on Windows Vista on several occasion. The system suddenly freeze-up while you are executing a Windows component (such as searching file on Windows Explorer or the desktop). Often, the system freeze-up occurred when you’re still working on several file or document and rebooting the system is not a good option to solve this problem because you will lose any unsaved data in open programs. However, there’s a way to fix this type of problem on Windows Vista without rebooting and losing your work:
1. When a Windows component freezes and becomes unresponsive, press Ctrl+Alt+Del.
2. Click the Start Task Manager button
3. Click the Processes tab.
4. In the Image Name column, find the explorer.exe process.
5. Right-click on explorer.exe and select End Process,
6. A Task Manager warning pop-up is displayed, Click Yes to end the process
This step should make the desktop, and possibly open applications, temporarily disappear.
7. In Task Manager, click on the File menu, and select New Task (Run…)
8. Type explorer.exe on the New Task windows, and click OK.
The Windows Explorer Shell should restarts and applications you had open previously, reappear.
That’s it, now you can continue working without worrying to lose data.
