17 years ago, C:\nul\nul crashed/BSOD Windows; now $MFT does for Windows < 10

History repeating itself: [Archive.is31607 – C:\nul\nul crashes/BSOD then, now it’s this:

All versions prior to Windows 10 and Windows Server 2016 seem vulnerable.

So add $MFT to this list:

The following device names have been known to render a system unstable: CON,
NUL, AUX, PRN, CLOCK$, COMx, LPT1, and CONFIG$.

Oh BTW: history repeated itself this year too. With NUL

In short, Steven Sheldon created a rust package named nul which broke the complete package manager on Windows:

BTW: one of my gripes on learning new languages is that they come with a whole new idiom of their ecosystem: rust, cargo, crates, all sound like being a truck mechanic to me.

[Archive.is] Working Windows XP & 7 demos. #FRENCHMAFIA: WannaCry — Decrypting files with WanaKiwi + Demos – Comae Technologies:

TL;DR;

DO NOT REBOOT your infected machines and TRY wanakiwi ASAP*!

*ASAP because prime numbers may be over written in memory after a while.

Two Quick Methods for Finding Shared Folders in Windows

Posted by jpluimers on 2017/05/01

In addition to the two methods mentioned at Two Quick Methods for Finding Shared Folders in Windows (use net share or compmgmt.msc) I like this one:

fsmgmt.msc

It directly gets you to the “Shared Folders” inside compmgmt.msc

Reducing the size of your Windows.edb (Search) and DataStore.edb (Update) databases

Posted by jpluimers on 2017/01/30

Windows Search: Windows.edb

If you use Windows Search (I don’t: I use Everything by VoidTools), your Windows.edb can grow ridiculously large. It is a single file, though it appears to be in two places because there is a symbolic link from C:\Users\All Users to C:\ProgramData :

C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Windows.edb
C:\Users\All Users\Microsoft\Search\Data\Applications\Windows\Windows.edb

This is how to reduce its size:

How to offline defrag the index

  1. Change the Windows Search service so that it does not automatically start. To do this, run the following command in cmd.exe:
    sc config wsearch start=disabled
  2. Run the following command to stop the Windows Search service:
    net stop wsearch
  3. Run the following command to perform offline compaction of the Windows.edb file:
    esentutl.exe /d %AllUsersProfile%\Microsoft\Search\Data\Applications\Windows\Windows.edb
  4. Run the following command to change the Windows Search service to delayed start:
    sc config wsearch start=delayed-auto
  5. Run the following command to start the service:
    net start wsearch

Notes:

  1. I did not perform the last 2 steps as I’ve kept Windows Search disabled.
  2. If you want to reduce the size of the C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Projects\SystemIndex\Indexer\CiFiles\ directory:
    1. Before step 1, choose what kind of Windows Search indexing options you want
    2. Between step 3 and 4, delete the directory

Windows Update: DataStore.edb

Windows Update uses the same database structure and is a single file:

C:\Windows\SoftwareDistribution\DataStore\DataStore.edb

This is how I reduced its size:

net stop wuauserv
net stop bits
esentutl.exe /d C:\Windows\SoftwareDistribution\DataStore\DataStore.edb
net start bits
net start wuauserv

Talking about Windows Update: you might also want to Clean Up the WinSxS Folder
