Windows 10: Control-Z Not Working System-Wide

My Control-Z shortcut for undo stopped working a few weeks ago. It doesn't work in any application or on the desktop. To be clear, the Undo function still works fine if selected from the menu or shortcut, but the keyboard combo CTRL-Z does nothing. All other keyboard shortcuts that I generally use (and I use a lot of them) still work fine, like CTRL-A, CTRL-C, CTRL-V, CTRL-W, CTRL-S, etc. To my knowledge, no other program on the computer uses CTRL-Z as a shortcut or hotkey. I have been using this PC for over a year and CTRL-Z worked fine until a few weeks ago.


I am unaware of any specific software installs or system updates that presaged this problem. I am running Windows 10 Pro x64 v1809 OS build 17763.379, fully updated as of this morning, with US English as the only installed language. Finally, this seems unlikely to be a system resource issue, since the PC is running a quad-core i7-6700K CPU @ 4GHz with 32 GB of RAM and has been rebooted multiple times.


Any suggestions greatly appreciated!

After applying the fix below, as suggested by Rose Ter in the community forum, system Z went away. It returned within a day and I reapplied the fix and it disappeared again. That was 4 days ago and system Z has not returned.





For your questions. That new drive labeled (Z: ) is the restore partition which is added to give you the option of restoring back to your previous version of Windows.
It is nothing to worry about, and should not be deleted.

For instance, that you still want to remove Drive Z, you can follow these steps:

1. Go to Control Panel and click on Network and Internet.

2. Under Internet Options, click on delete browsing history and cookies.

3. Under browsing history, click settings make sure you have it on automatic and have 1024 MB in the box.

4. Click ok, then restart your computer this should get rid of the Drive Z.
