Windows 7: Suspicious 'Undo Rename' and delayed 'Undo Delete'

This. I should probably have written "Windows Explorer". My apoligies.

I understand how it all works. I'll try to elaborate my issue.
- PC is off.
- I switch on PC and boot into windows.
- I open my browser to view content. I see a video I would like to watch but it's a bit dark. I decide i can brighten screen by going into gfx card setting.
- I go to desktop. Right-click on desktop because i can access gfx control panel shortcut from the context-menu.
- Hold on! Why is there an "Undo Rename" item in my context-menu?! I never did any file/folder renaming since I booted my PC.
- Curiously I click on "Undo Rename". Now it shows "Undo Move". WTF?! I haven't moved any file/folder either.
I haven't made any kind of file/folder copy/delete/move/rename operation since boot.

My questions is; Does Windows remember file/folder operations from last boot and carry it over to next boot? If not. Is there a registry entry that shows what file/folder Explorer will "Undo/Redo <operation>" on? If so. Please share.

Cheers.

PS. I mean... Unless I have the memory of a gold fish (which is kind of worrying me atm), I am quite sure i didn't do any file/folder operations before seeing this item in my context-menu.

Hi, I've done some research and those "Undo Rename and Undo Delete" entries are normal. They appear after a user has renamed or deleted something. I find that those entries are not supposed to exist after a reboot. At least on my machine they vanish after a reboot.

I reckon that it might be possible to relace your shell32.dll file from your Win 7 Ultimate ISO or DVD and replace it in your System32 and SysWOW64 folders and in theory it should return your context menu to default settings but I'm not at all confident that this will actually fix things. It's probably better to seek help on this from a more experienced forum member.

In any case a system image backup before going ahead is recommended.

It's OK now. I've found out what caused these suspicious entries. Turns out, if you copy/move/rename/delete a favourites link inside of Internet Explorer, it will use the shell to complete the operation causing a phantom unde/redo entry to appear in Windows Explorer.
I've been using Firefox for so long that I totally forgot that IE favourites are separate .url files inside of folders on the drive, whereas FF bookmarks are stored in a single file.

Anyways... Thanks for your time, Callender.

For those who come across a phantom 'Undo/Redo <operarion>' entry appearing in Windows Explorer, or have just forgotten what file you last copied/moved/deleted/renamed, and would like to know what file Explorer will modify...
In Windows Explorer, set the layout to show both the 'Menu bar' and 'Status bar'. When both are visible, click 'Edit' on the 'Menu bar' and hover over the 'Undo/Redo' entry. The name of the file will be displayed on the 'Status bar'.
Unfortunately, it doesn't show directory structures.

Cheers.
