Fix WU is a tiny and portable software utility whose purpose is to resolve Windows errors regarding system updates, by re-registering missing DLL, OCX and AX files.
As installation is not a prerequisite, you can just drop the executable file anywhere on the hard disk and click it to run.
There is also the possibility of moving Fix WU to a USB flash disk or similar storage device, in order to run it on any workstation with faulty Windows updates.
An important aspect to take into account is that the Windows registry section does not get entry updates, and leftovers are not kept on the hard disk after removing the utility.
The interface of Fix WU is based on a single, small window, where the "what you see is what you get" concept clearly applies, as there are no other options available, aside from the two buttons visible in the main frame, assigned to fixing Windows updates and exiting the application, respectively.
After triggering the primary action of Fix WU, the tool takes little time to add the missing DLL, OCX or AX files to the Windows registry. At the end of the task it shows a message dialog informing you of the task's success or failure. However, you cannot get thorough details on the performed task.
The feature-limited program is low-demanding when it comes to CPU and RAM, so it doesn't put a strain on computer performance. No error dialogs have been shown throughout our evaluation, and the app did not hang or crash. To sum things up, Fix WU serves its purpose and restores the proper functioning of Windows updates.
