Hi All,

Windows Explorer crashes every time after running Disk Cleanup on Drive C:\.

Since when this problem started?

Try run disk defragment first.

Check for update and install all updates.

Also, can you open the Action Center on the taskbar > Maintenance > View reliability history > View all problem reports

Can you right-click on a few of the "Windows Explorer"  "Stopped working" errors > View technical details

What are the details of the errors?

There is a "Copy to Clipboard" link at the bottom.

Paste the information first into Notepad and then recopy the information from Notepad to post here.

Hi and Thank you all for the replies,

I do use Network Magic and all Windows Updates, except for Language Packs are installed.

And I have TuneUp Utilities 2011, that defragments the Hard Drive in the Background.
