Regshot2 Unicode v2.0.1.70

webfork on 26 Feb 2015
  • 612KB (uncompressed)
  • Suggested by Lupo73

Regshot2 Unicode is a registry change and file system change detection diff tool that takes snapshots, generates HTML reports, and creates automatic REG undo/redo scripts. The program can save/load snapshots to file for later use, while registry path and file path inclusion/exclusion rules can be set to include/exclude paths in the snapshots.

The program includes two components:

  • Registry Shot - It will automatically generate UNDO.REG and REDO.reg registry scripts based upon the difference between two snapshots taken at two points in time.
  • File Shot - will catch file changes based on either timestamp, size, or CRC32/MD5 and report these changes in an HTML file

Note: Regshot2 Unicode is not an update to Regshot, but a unique program. Although it shares a similar interface, it is a code fork by a different author and has many more features.

System Requirements: Win2K / WinXP / Vista / Win7 / Win8
Writes settings to: Application folder
Stealth: ? Yes
Unicode support: Yes
License: Freeware
How to extract: Download the ZIP package and extract to a folder of your choice. Launch Regshot.exe.

Weird, upon a second attempt it started in english now, I swear I wasn't crazy, maybe it had something to do with it not starting correctly in Sandboxie or maybe not as administrator or something. :/

@Special: make sure your "regshot.ini" file starts with:

An alternative method is to edit the language.ini file (delete all languages but English)

Regshot v1.9.0

webfork on 22 Nov 2013
  • 129KB (uncompressed)
  • Suggested by Crash

Regshot is a small registry compare utility that allows you to take a snapshot of your registry make changes to your system (such as installing a program) and then taking a second snapshot to compare. The comparison report can be produced in text or HTML format and contains a list of all modifications that have taken place between the first and second snapshot. In addition, you can also specify folders (with subfolders) to be scanned for changes as well.

Alternatively, RegShot Portable automatically switches between 32 and 64-bit and adjusts paths.

System Requirements: Win95 / Win98 / WinME / WinNT / Win2K / WinXP / Vista
Writes settings to: Application folder
Stealth: ? Yes
License: GPL
How to extract: Download the source + binary ZIP package and extract to a folder of your choice. Launch regshot.exe.

Optionally, delete the src subfolder.

robertcollier4 - The Regshot2 you are posting about is a different app. It's either a totally different freeware app that copied the layout or an app illegally using the real Regshot's code as a base and not distributing the newer source as required by the GPL. Either way, this entry is about the real Regshot, which is open source, Unicode, portable and has 32-bit and 64-bit versions (the version even switches between them automatically). It's also under active development unlike 'RegShot2' which is abandoned.

Different entry has been created for Regshot2:
I feel Regshot2 is superior because of its ability to detect and report on filesystem changes and also because it creates ready-to-merge UNDO.reg and REDO.reg script files for you.

Auslogics Registry Defrag v6.3.0.5

Checker on 15 Mar 2014

Auslogics Registry Defrag defragments and compacts the Windows Registry in less than a minute. It scans through the registry to remove slack spaces, reducing the registry size and ultimately the amount of RAM the registry takes up, improving drive performance.

Note: Speed benefits on a SSD-based (flash media) installation will be minimal.

System Requirements: Win2K / WinXP / Vista / Win7
Writes settings to: Windows registry.
Stealth: ? No
Unicode support: Yes
License: Freeware
How to extract:
  1. Download the installer and extract to a folder of your choice
  2. The application files are located in the {app} subfolder
  3. Rename regdefrag,1.exe to regdefrag.exe and launch
What's new?
  • Added free space availability check before creating Rescue Center backups. If there is not enough free space on a disk, user has the option to abort the operation or proceed without creating a backup.
  • Fixed memory leaks, optimized code and algorithms, which improved the speed of practically every tool in the program.
  • All modules that work with hard drives were optimized to correctly process large data volumes, namely the Rescue Center will now correctly create and restore backups larger than 2 GB.
  • Made numerous corrections to language files.
  • Made numerous changes to modules; interface to make them more convenient and easier to work with.
  • Improved reports and operation results display in response to user feedback. Now this information is easier to understand.
  • Added partial Windows 8 compatibility. Full compatibility will be implemented in BoostSpeed version 5.4
  • Corrected all known bugs.
  • Corrected installer errors, optimized program installation and uninstallation.

My only experience with a registry defragger left my system unable to boot (used backup registry to fix). I'm not writing this to take a cheap shot at the makers of this app but I think a better explanation is needed on their web pages. Most of the 'bullet-point' features sound like hype (reduce size, windows=faster, performance=faster).

Not sure what "remove slack spaces" and "Eliminates structural defects in the Registry" mean... Registry cleaners, disk defraggers, contiguous blocks of data, etc ... I understand. Registry compactors that fix structural defects... I don't understand.

The program is freeware again, but still not portable and won't run from external or network drives.

Windows Registry Recovery v1.5.2.0

Andrew Lee on 12 Feb 2013
  • 2MB (uncompressed)
  • Suggested by AlephX

Windows Registry Recovery allows to directly read files containing Windows registry hives and extract many useful information about the configuration and windows installation settings of the host machine.

System Requirements: Win95 / Win98 / WinME / WinNT / Win2K / WinXP / Vista / Win7
Writes settings to: None. There are no user-changeable settings, but it does write some control/window related settings to the registry, so it is best avoided by "stealth" purists.
Stealth: ? No. HKEY_CURRENT_USER\Software\MiTeC\Wrr
License: Freeware
How to extract: Download the ZIP package and extract to a folder of your choice. Launch the program by double-clicking on WRR.exe.

You do nothing wrong. It's a peace of SHIT !!! Waste of time !!! At least a single line of help how to use it would be decency!

Raj Sharma on 2009-12-26 02:11

I find it a good Program. Only one of its kind. You should know where your registry hives are.

I would be interested in hearing about alternatives to this program.

BigRin on 2010-07-12 07:30

I am also interested in a simple alternative program.

billybob on 2010-07-12 09:24

To previous commenters: if you take a snapshot of the entire PC (every file, all registry keys, etc), and then, many days later, you want a report of everything that changed, then naturally temporary files must be created to persistently track the changes from the original snapshot. This app is not meant to be "ultra-small-USB-stick" portable. Not sure what kind of alternative would be possible. Also, if you want to see all changes, and there were 90,000+ new reg keys, it's not the fault of WhatChanged that there is so much output (Richard is right about this). You can choose to view the output in whatever program you want (and Firefox is not a giant text database viewer).
