One thing that I use almost every minute is the Windows Run box (WINDOWS+R). It let's you type a path and auto-completes it really quickly so that you can jump to any dir in no time.

My problem is that I recently swapped disks and re-organized content so a few of the drive letters changed while most (but not all) the dir structure stayed the same. Now the auto-complete is giving me a lot of old results that don't physically exist anymore and it's not only annoying but the advantage of speed is not there anymore because I now have to check for old results in my auto-complete!

How can I clear that auto-complete's cache?

Thanks!

EDIT: I'm not talking about how to clear the last run items from the Windows Start menu. This is completely different. What I'm talking about auto-completes directories in the file system and is "remembering" old auto-completed paths (which are NOT programs, just paths).

This question came from our site for professional and enthusiast programmers.

    
I thought that the autocomplete cache just selected from the last run items and so they were the same thing. Sorry if that's not the case. I also just cleared the recent documents checkbox in the taskbar properties and that didn't work either... I am on an XP machine at the moment. –  Tom Chantler May 24 '11 at 14:30

Try looking here: http://www.wikihow.com/Delete-Run-History-in-Windows

EDIT: I am on an XP machine, so I can't test this next bit, but does it work? http://windows.microsoft.com/en-US/windows-vista/Clear-the-Run-history-on-the-Start-menu

Seems that I was unable to find that "Clear" button in my Windows 7. Was it moved? –  Uwe Keim May 24 '11 at 13:54
    
While I couldn't find it wither, this is the same thing as Stuart Dunkeld's answer: the list of the last run items, not the auto-complete cache. –  Anonymous May 24 '11 at 14:10

@Dommer, I followed the link in your EDIT and did what said there. I already had those options disabled... but... I checked them and hit Apply. I opened and closed a few programs, and then went back there and unchecked them again, hit Apply, and my auto-complete is now working properly again! So, in a weird way... it worked! –  Anonymous May 24 '11 at 14:47
    
Hey that's awesome. Glad to (possibly) have been of help! At least this might help anybody else who encounters the same problem. –  Tom Chantler May 24 '11 at 14:54

Clear the entries in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU

Edit: AutoComplete in the Run box is set in (of course) Internet Explorer's settings (Content Tab / AutoComplete): there's a button to Delete Autocomplete History. If that doesn't work, you could try turning AutoComplete off, rebooting, and turning it on again.

This gives me the list of the last run items (which I had already disabled), not the auto-complete cache. –  Anonymous May 24 '11 at 14:10
    
You made me laugh with the "(of course)" comment... but I just found a solution (see Dommer's post). Thanks, anyways! –  Anonymous May 24 '11 at 14:49

I would do it the following way:

  1. Get SysInternal's Process Monitor
  2. Filter to "Explorer.exe" as the process/file
  3. Execute Win+R
  4. See what is happening in Process Monitor (I assume that some registry/files are involved)
  5. See whether you can delete those found entries/contents.

Update

Seems others have better answers than I, please see those for a direct solution to your question.

+1 for a nice answer, inspired by Mark Russinovich no doubt! –  Tom Chantler May 24 '11 at 13:53
    
@Dommer Thank you :-) –  Uwe Keim May 24 '11 at 13:55
    
I tried doing this but filtering Explorer.exe left me with 33.405 things to look at and to be quite honest I didn't really know what to do after that. I tried Win+R and typing some stuff but didn't notice any changes :( –  Anonymous May 24 '11 at 14:12

It's definitely not stored in the registry as I've searched it, so no idea where it lives.

The only way I've found to do this is to use CCleaner, http://www.piriform.com/ccleaner/download .

At least on Windows 8 the auto-complete history you are looking for is at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\TypedPaths

A solid state OS drive and NirSoft's RegScanner and you're set to find anything in the registry quickly.
