Windows 98 - Optimize and reduce the Windows registry

November 25, 2013
Updated: April 14, 2022
Quick overview:

The installation and uninstallation of programs, demos and games causes downright chaos in the Windows registry: It swells to a considerable size and is split into fragments due to the resulting gaps. Windows therefore has to load this overcrowded registry into memory every time the system is started, which costs time and resources. Accessing it also proves to be extremely slow due to the free gaps, which not only affects speed but also leads to instability.

Optimize and reduce the size of the registry

DOS offers the option of reducing the registry and deleting these gaps so that access is faster and resources are conserved:

1. While Windows is running, click Start > Exit > Shut down. You are now in MS-DOS.

2. Now type in the command scanreg /fix. Confirming with Enter causes this command to be executed, which repairs the registry and deletes free gaps.

3. Immediately afterwards, write the command scanreg /opt, which reduces and defragments the Windows registry. Immediately after executing this command, the core of Windows is fully operational again and your system is faster than ever.

Windows version with top-class registry optimization

If you want to bypass these steps via the well-known DOS in the future, you can also make do with a Windows version of this tweak, which either repairs or optimizes the Windows registry with a double-click. Proceed as follows:

1. Right-click on the desktop and select New/Link.

2. Now enter C:\WINDOWS\SCANREGW.EXE /FIX in the field that appears and confirm with Enter.

3. Now give this shortcut a meaningful name such as Registration repair and confirm with OK. You can also repeat this step for the command C:\WINDOWS\SCANREGW.EXE /OPT, so that optimal defragmentation is always guaranteed.

NOTE FOR NEW PUBLICATION: This article was produced by Sandro Villinger and comes from the Windows Tweaks archive, which has been built up since the late 1990s.

Founded Windows Tweaks as a teenager in 2001, his helpful PC tricks made it Germany's most visited Windows site (at the time Sandro looked like this). He then went on to write for international publications such as PC-Praxis, Computerbild, PCWorld in the USA, IMTEST.de and Hifi.de. Sandro's main job is as Global Product Marketing Lead and Consultant for various global tech companies, including Microsoft, AVG, Avast, Nero, TeamViewer, Swiss IT Security Group and now currently in the fintech sector for Gendigital. But he can't get rid of his passion and shares his tweaks here again. Privately, he enjoys traveling the world and loves Asia, especially Japan, Singapore and Korea, but also natural places like Iceland and the Nordics. You can reach Sandro via e-mail.
