Opening REGTRANS-MS files

Did your computer fail to open a REGTRANS-MS file? We explain what REGTRANS-MS files are and recommend software that we know can open or convert your REGTRANS-MS files.

What is a REGTRANS-MS file?

The .regtrans-ms file extension is used for dynamically-created files that are used by the Windows Vista and Windows 7 operating systems.

The REGTRANS-MS files are created in order to prevent the Windows registry from becoming corrupt. When a change to the registry is made, the changes are written to the REGTRANS-MS file before the change is written to the actual Windows registry. This allows the system to ensure that everything will work properly before permanent changes are made.

When the changes have been made and the system is working properly, the changes are normally written to the registry automatically and the REGTRANS-MS file is usually deleted.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
