VHD Attach 4.11 – Medo’s Home Page

Posted by jpluimers on 2017/06/05

Brilliant:

This is small tool that adds Attach and Detach option to contextual (aka right-click) menu of Virtual disk (vhd) files. That enables those operations to be done without trip to Disk Management console. Detach option is available on hard drive contextual menu also (if selected in options).

What’s got a vast attack surface and runs on Linux? Windows Defender, of course • The Register

Posted by jpluimers on 2017/05/26

Penguinistas, rejoice: Tavis Ormandy lets you fuzz Windows

Cool, as they now can fuzz Windows Defender and have Microsoft make it better so all Windows 8+ users can profit from it.

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:

Posted by jpluimers on 2017/05/15

PatchCleaner just cleaned out 10-20 gigabyte per VM for most of my Windows 7-8.x VMs. After that, the updates still worked fine.

So it indeed does:

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

Battery history on Windows 10 via powercfg batteryreport

Nice html report of your battery state in Windows 8 and 10 where 14 is the number of days:

powercfg /batteryreport /output "%temp%\battery_report.html" /Duration 14

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
