Wufuc Versions Save

Some of the features I implemented in the last version of wufuc have turned out to not be as useful as I thought, or caused more problems than they were worth (crash detection, API hooking, etc). So I brought wufuc back to basics with this version.

Changes in this release

• Removed crash-detection. (fixes #148)
• Removed all injection and API hooking routines. (fixes #146 and hopefully #147)
• Patching routines are now fully external:
  • Way more stable and less invasive, crashes and hangs should be pretty much non-existent.
  • Re-introduces the incompatibility with UpdatePack7R2 or other software that modify wuauserv's ServiceDll value in the registry. You can still work around this manually by using the provided Restore_wuauserv.reg file.
  • Introduces a potential race condition where the "Unsupported hardware" popup could display for a short period of time before wufuc is able to patch it. Should this happen, just close the popup and it should not display again.
• Changed the log file text encoding format from UTF-16LE (without BOM) to UTF-8 (without BOM) to improve compatibility with various text editors. Because of this, the log file is now located at C:\ProgramData\wufuc\wufuc.1.log.

After many months of development, the new version has arrived!

Because of what happened with the v0.8 release (#110, #111, #112, #113, #114, #120), I decided to scrap all of that code and start over with something that more closely resembles the v0.7 code base, albeit with many needed improvements and fixes. I'm hoping this will be the last necessary major release.

Important bits are in bold.

Changes in this release:

• Added a user log-in trigger to the scheduled task. This should solve the problem where sometimes the task doesn't run. (fixes #98, #116, #137)
• Added support for injecting into Windows Update when it is configured to run in its own process. There is a caveat however, see below. (fixes #131)
• Fixed conflict with UpdatePack7R2 (and WuaCpuFix) by hooking RegQueryValueExW and fixing the path to wuaueng.dll at run time. This will only work if Windows Update is configured to run in a shared service host, click here for a work-around. (fixes #100)
• Added a check that will skip the patching procedure if the version of wuaueng.dll is too low. This means you can now safely install wufuc prior to any updates, and it will automatically start working once it's needed. (fixes #99, #129)
• Added crash loop detection and prevention. If a process that wufuc has injected itself into crashes, it will be detected and logged. After a certain threshold of crashes (currently 3), it will stop attempting to inject itself until the next time you restart. This is to avoid rendering your system unusable in the case of a very serious bug.
• Improved logging functions. The log file is now located at C:\ProgramData\wufuc\wufuc.log.
• Other stability improvements and bug fixes.

Changes to the installers:

• Removed the error message that displays in the installers when wuaueng.dll is below the minimum supported version. (fixes #99, #129)
• Added command line switches to the batch setup scripts. You can use this to skip user interaction prompts for a fully automated installation/uninstallation. See the FAQ for more information.

Other news:

• We have a Discord server now, come by and say hello! Contributors, donors, and documentation translators get their own user roles. Ping zeffy after you join if you want to be tagged as such.

Update 10/16/17: Downloads pulled for now due to some serious issues have been encountered on Windows 8.1. If you installed this version, I recommend you uninstall it. If the uninstaller is not working, follow these instructions to remove it manually.

Installer changes

• MSI: Added Hungarian, Portuguese (Brazil), Danish, and Slovenian languages
• Batch: Integrated sfc scan into install process
• Batch: Now compares the version number of wuaueng.dll instead of querying the list of installed updates, the same method used by the MSI setup (much faster than before)

Other changes

• Minor performance improvements which should result in less overhead when starting some services while wufuc is active

No need to update if you already installed the last version.

Added the following languages to the installer:

• Dutch
• Finnish
• German
• Italian
• Spanish

Also, I added back the unified zip package that includes both x64 and x86 builds as per #73.

I've finished the Windows installer packages thanks to the wonderful people over at Advanced Installer who generously decided to grant me an open source license for their awesome software!

Installer features:

• Automatically triggers sfc scan on wuaueng.dll and reverts the old (<0.6) patch (restart required to apply changes)
• Cleanly uninstalls without the need to restart, and gives the option to remove wufuc's .log files
• Installs shortcuts to enable/disable wufuc into your start menu
• Installer automatically uses your operating system language. (Only Simplified Chinese, Traditional Chinese, English, French, Japanese, Korean, Polish, and Russian are currently supported, but I can add others if requested.)

Other changes in this release:

• Optimized DLL injection
• Fixed a couple memory leaks
• Russian and French translations of README.md and CONTRIBUTING.md now available thanks to @minlexx and @stevemoreau! (if you are interested in contributing your own translations, check out #68)

If you encounter any issues with the new installer packages, please create an issue so I can fix it as soon as possible.

Changes in this release:

• Write processor and operating system information to log
• Changed log messages to be more uniform
• Refuse to load when in WoW64 mode (wufuc32.dll won't work on 64-bit operating system)
• Simplified some code, fixed a few potential bugs, and made security improvements

NO MSI INSTALLER YET, COMING SOON™!

Changes in this release:

• New logging system! There will now be .log files created in wufuc's install directory so you don't have to download DebugView to see them anymore. See the contributing guidelines for more information.
• A few changes to the installer that should make it more reliable, and may solve issues people were having with wufuc not activating until after a system restart.
• Added more helpful error messages to the installer.
• Added preview updates KB4022168 and KB4022720 to supported updates list in installer script (only tested Windows 7 x64).

Minor changes, mostly for helping with issues. I included a new script called dbgview_helper.bat which automatically restarts wufuc and wuauserv so that you can easily get a debug log from DebugView.

See reporting an issue in the README for more information.

In this release:

• Fixed completely broken x86 support (#47)
• KB4022726, KB4022722, KB4022719 and KB4022717 are now officially supported
• Improved the installer and utility scripts usability
• Switched to better byte pattern matching algorithm (credits to @x64dbg for it, I just ported it from C++ to C)
• Better error handling and OS version detection
• Other minor stuff

Cheers everyone!
