Taskbar vanished!!!

Windows.

Try using CCleaner to fix up the registry.

Check if explorer.exe is running in process task manager . . I usually run this process when comp hangs and taskbar goes . .

I think you have resized the task bar completely. check if you can see a thin blue bar(unless you have changed the theme). hover the cursor near the bottom of the screen and see if the resize icon appears. Press the window button and see if the start menu appears.

I didn't resize the taskbar.
I never do that and I hate that.

In the morning, when electricity went off, PC shutdown automatically (I've set it through APC). Next when it restarted automatically as electricity came, its not showing taskbar.

^^ did you check that ? press Win Key and check.

This is how it shows now.

And I'm doing all task by pressing windows key
or Win+R key combinations.

Well, I've found something, let me try and I'll post result.

Fixed!!!

What I did:- (well last time I told I found something....that something didn't work)
On startup disabled: Everything that I don't like. Mainly theme based services.
Went to safe mode, did a registry scan with "UniBluRegistryBooster". It found 40 issues (CCleaner found nothing!!! my old faithful betrayed me )

Restarted machine...........andf voila!!!!!!!!

I'm back baby!!!!!!! Yeppyyyyyyyyy
