Rosenthal UnInstall (™) automatically removes unwanted Windows and DOS programs, files, directories and restore the system's AUTOEXEC.BAT, CONFIG.SYS, WIN.INI, SYSTEM.INI and registry files (user.dat and system.dat). Now runs under DOS and all versions of Windows, including Win95. Run Rosenthal UnInstall before you add anything new to your system. New programs can then be added and, at your option, kept, or deleted and the system completely returned to normal.

Rosenthal UnInstall is an excellent program for keeping your system neat, clean, and free of unwanted program files. It can remove even the most complex program installations *and* restore your system files! It's a program I wouldn't be without. Rosenthal History, provided free to registered users of Rosenthal Uninstall, keeps an ongoing history of all changes to your system! This is a must-have combo for anyone who uses software! Excellent!

If you are the sort of person who likes to experiment with new programs, you can't afford to be without Rosenthal UnInstall. It will save you untold aggravation, and help to keep your system healthy.

I have tried several Windows uninstallers before running across Rosenthal UnInstall and found them slow and somewhat complicated in the basic learning curve. With this little DOS program, I had it installed and running in minutes with its short and to the point documentation. No frills, no pretty graphics or pictures of your disk, just pure uninstalling power in this package!

Rosenthal Uninstall not only located all of the files but efficiently removed them in seconds!

Every so often, I discover a company that hits on just the right product and delivers it. This time, it's a small company called Rosenthal Engineering....

Rosenthal UnInstall makes removing files, program groups and icons, and restoring your configuration files a quick, easy, and pain-free procedure.

Rosenthal Year 2000 Fix (™) (and CMOS/Clock battery monitor).
Full compliance through the millennium is assured with this free bonus utility just for trying
"The Rosenthal Utilities (™) ".

Disk Drive Cleaner from Rosenthal Engineering safely and effectively removes debris from the delicate read/write heads of floppy disk drives. Prevents data loss, unreliable performance and errors often traced to microscopic foreign particles, dirt, dust, oxides and smoke that accumulates on the floppy disk drive heads. Preventative maintenance takes less than four minutes with support for standard diskette drives as well as commercial automatic mass disk duplicators. "Disk Drive Cleaner" may be run without a special cleaning disk for demonstration and evaluation.

System Monitor From Rosenthal Engineering monitors and reports system changes and reveals problems early to maintain performance, correct hardware/software and MS Windows problems.

Each time the computer is used, System Monitor re-evaluates the system by testing by extensively monitoring thousands of performance indicators to discover and resolve problems early. Tracking changes provides technical support professionals vital diagnostic trouble shooting information.

Rosenthal's Virus Simulator Safely Validate Your Anti-Virus Protection.

"Unreservedly recommended!" by "Computer Virus Developments Quarterly", to test anti-virus measures or demonstrate how they work. This latest version of Virus Simulator is an absolute necessity, for anyone seriously interested in defending against viruses. Government agencies, businesses, security consultants, law enforcement, institutions and system administrators, employ Virus Simulator when conducting internal security audits and training.

Rosenthal Conflict Resolver Hardware and software diagnostics combine to identify, resolve and prevent all PC system DMA and IRQ conflicts for DOS, Windows, Windows 95, Windows NT and OS/2. From the earliest PCs to today's most sophisticated plug-and-play components, all are supported, even when systems mix old and new technologies.

Rosenthal Conflict Resolver insures systems are configured correctly, or optimized before installing additional new devices, peripheral hardware or operating systems like Windows 95, NT or OS/2.

Rosenthal Format R-Format replaces the standard floppy disk format so it no longer hangs the system during start up when the diskette is left in the A: drive. An embedded graphic and text message of your choice are displayed and the system then boots normally. The disk otherwise functions identically. The example graphic file R-FORMAT.PCX may be replaced with your own. Company logos, school emblems, product trademarks, club insignia etc. are just a few suggestions. Especially useful to software producers.

Rosenthal System Workout (™) By repeatedly exercising thousands of low level tests, System Workout confirms the reliable performance of new or upgraded systems and/or when changes are made like installing new hardware or software. Especially difficult problems like intermittent, marginal performance errors and conflicts are revealed. As System Workout logs more time and tests, confidence in reliability increases. Diagnostics conducted continuously over an extended time are recorded as a text report file. Beginners can easily use this program to generate a report with the sophisticated information valuable to more advanced trouble shooters.

Rosenthal Un_Dup Duplicate files waste valuable disk space, so "Rosenthal Un_Dup" finds any files that are redundant and may be removed. The path statement is optimized and directed to the remaining identical files. Files must be identical in name, size and contents to be considered duplicates. The path statement sequence order is reorganized based on the actual directory structure of the disks to optimize access times for the most efficient search. A must have utility to optimize larger hard drives and make the most efficient use of small ones.

Rosenthal WINLITE (™) compresses MS-Windows programs, to dramatically reduce their size. Programs compressed by Rosenthal WinLite are functionally identical to the originals, only smaller. For example, consider the 180k "Solitaire" game that is bundled with MS-Windows. Rosenthal Winlite compresses this file to less than 77k, or 43% of its original size. The smaller, more efficient programs save disk space, LAN overhead, disk caching resources and discourage reverse engineering.

Rosenthal WinLite inputs a big program... and outputs a small one. The process is totally automatic and requires no additional drivers and no modification to source code or linking.
