Unofficial Updates

This section is going to be reorganised. Until then you can view the old website to get information about the Unofficial Service Pack 5, UURollup, Update Rollup 2 and other unofficial packages for Windows 2000.

Windows 2000 Updates Lists

Jump down the page to the following updates lists:
Internet Explorer
Windows Media
Microsoft Update

The updates here are sorted into lists by component. The lists are designed for use with HFSLIP. As a result, they may omit certain updates (in contrast to other similar lists). The newest version of HFSLIP can be downloaded from Mimo's website. Basic how-to use HFSLIP is also available there. For other help with HFSLIP, post your query in the HFSLIP Forum at MSFN. Likewise, please post there any corrections you think necessary for the lists.

Updates here are multilanguage, unless otherwise stated. Note that in some cases you must choose the correct version of an update to match the version of a system component you have decided to install. Before using this page, please read the disclaimer. You might also want to brew yourself some strong tea or coffee.



Microsoft have removed links to عربي updates from their website. For the time being, you should download them using Microsoft Update Catalog (works only in Internet Explorer!). Unfortunately, some updates seem to be missing from there.

[hotfix]818801 (replaced by [hotfix]888111)
[Windows XP]2736233 (replaced by [Windows XP]2900986)
[Windows XP]2794119 (replaced by [Windows 2003]2981580)
2798897 (replaced by 2982792)
Flash Player SWFLASH.CAB. Using IE5 / IE6 to browse the Internet is unsafe. It is recommended to avoid IE and use an alternative browser instead. Therefore, the IE-only Flash Player is no longer required in a typical Windows 2000 installation.
Root Certificates 36.0.2195.0 (replaced by Root Certificates 41.0.2195.0)
Removed all info about Windows Media Player 7. WMP7 was released after Windows 2000 and has never been part of it. There is no reason to use WMP7 at this point. Either install WMP9 with its updates or stick to WMP6.4.
Removed all [unofficial]unofficial updates from the updates list.

Update types

Windows XP / 2003
were produced by Microsoft to fix specific problems, and are issued on a per-request, optional basis via email (they are not generally available like other updates). Unlike updates on general release, they were not tested extensively. For example, they did not undergo regression testing. As such, some of these hotfixes may cause unforeseen problems for some users. Hotfixes have a green background and a mail icon for their links.
Superseded updates
are those replaced by newer hotfixes from Microsoft. The description for each superseded update has a link to the newer update that supersedes it. Superseded updates are listed here for those who prefer not to use hotfixes. They are distinguished here from other updates by a gray background, gray text and a cross sign for their links.
Problematic updates
are official updates and hotfixes which are proven to cause issues after installation. It is generally recommended to be careful when using them. Problematic updates have a red background and an exclamation mark icon for their links.

Update scenarios

For the latest updates (of all types):
Disregard the gray-background superseded updates.
Use the others.
For the latest updates only (excluding hotfixes):
Disregard the green-background hotfixes.
Use superseded updates.
Use the others.


Although much effort has been made to avoid errors in these lists, nevertheless they sometimes occur. You use the information on this page at your own risk. Likewise, you use updates and hotfixes at your own risk. You are solely responsible for the results you obtain for your system.

This hotfix is problematic. Slipstreaming it causes Error 87 with SclgNtfy (Secondary Logon Service Notification), but installing it manually does not. However, installing manually will overwrite some newer files, because they share the same build number. Workaround: install this update manually, thus: extract 884872 to its own folder (from a command prompt, using the -x switch). Then extract Crypt32.dll and Cryptnet.dll from 955417, and Browser.dll from 891861 (Update Rollup 1). Replace the corresponding files from 884872's folder with these latter (newer) files. Finally, install 884872 manually by clicking update.exe in 884872's "update" subfolderHF\[problematic][hotfix]Windows2000-KB884872-x86-XXX.exe

If installing manually, it will overwrite a newer Browser.dll from 891861 (Update Rollup 1), because it shares the same build number (even though it is older, differing in size and date). Workaround if installing manually: extract 894190 to its own folder (from a command prompt, using the -x switch). Then extract Browser.dll from 891861 (Update Rollup 1). Replace the corresponding file from 894190's folder with this latter (newer) file. Finally, install 894190 manually by clicking update.exe in 894190's "update" subfolderHF\[hotfix]Windows2000-KB894190-x86-XXX.exe
