Hi, I have save some reg tweaks in some .reg files. But now I got registry import issue on Windows 7 Ent, I am a local admin.. What can this be? [Window Title] Registry Editor [Content] Cannot import C:\Users\admpersai\Desktop\s.reg: Not all data was successfully written to the registry. Some keys are open by the system or other processes. [OK] /SaiTech

That error means that the registry settings that you are trying to import refer to programs that are currently running and so those settings may not be implemented. Try this: Boot into safe mode and close all open apps. then try merging the registry backup.

Try opening regedit as "Run as administrator" when you open it from run box it defaults to regular user session i think. (right click on it and run as administrator)

This is rare, but some keys can only be modified by System.

Thanks all for helping me, The updat on this is that I exported from one computer and imported on other computer. Why it not worked was that some registry settings was unique from the exported computer. So I tweaked the exported reg key to fit the imported computer then it work. So it was my misstake not to careful with the exported reg keys. Thanks all for helping me, this is a fantastic forum. Happy New Year. /SaiTech

Hello! My Win7 Pro x64 system also won't accept a registry update, even in safe mode. When I run a .reg file I get "Not all data written to the registry. Some keys are open by the system or other processes". When I try to edit it within regedit I get "Cannot edit ResourceDLL: Error writing the value's new contents." The key is HKEY_CLASSES_ROOT\CLSID\{B98A2BEA-7D42-4558-8BD1-832F41BAC6FD}\Instance\InitPropertyBag the problem relates to a known issue with Acronis TrueImage Home 2011 that doesn't clean up correctly when un-installed. It is described on the Acronis Knowledge base. How, please, can one edit keys that appear permanently locked? I have taken ownership of the key and given the Administrator Group (of which I'm a member) full control but nothing seems to make it editable. Is there a way to edit the registry from outside the running system? A System Repair disk/USB is not an option because the problem I'm trying to fix is that the Backup/Restore screen that also offers to create a system repair disk is blanked out! I could run from a Win7 installation DVD or from a Vista partition. Regards, Philip
