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:
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
- 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- Run the following command to stop the Windows Search service:
net stop wsearch- Run the following command to perform offline compaction of the Windows.edb file:
esentutl.exe /d %AllUsersProfile%\Microsoft\Search\Data\Applications\Windows\Windows.edb- Run the following command to change the Windows Search service to delayed start:
sc config wsearch start= delayed-auto- Run the following command to start the service:
net start wsearch
Notes:
- I did not perform the last 2 steps as I’ve kept Windows Search disabled.
- If you want to reduce the size of the
C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Projects\SystemIndex\Indexer\CiFiles\directory:- Before step 1, choose what kind of Windows Search indexing options you want
- 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

permissions – recursively change owner windows 7 – Super User
Posted by jpluimers on 2016/10/27
Slightly updated the answer the /D Y part will recursively accept taking ownership when directory listing is denied in the permissions:
To fix really broken permissions, the best is to run these two commands one after the other:
takeown /F /D Y "C:\path\to\folder" /R icacls "C:\path\to\folder" /reset /TThe first one will give you ownership of all the files, however that might not be enough, for example if all the files have the read/write/exec permissions set to “deny”. You own the files but still cannot do anything with them.
In that case, run the second command, which will fix the broken permissions.

FileZilla on Windows is waaaay faster than WinSCP
Posted by jpluimers on 2016/10/21
Not sure why yet, but on a gigabit network between a Windows 2008 R2 Server and a Proxmox KVM machine, WinSCP gets around 10 megabit/second and FileZilla > 30 megabit/second.
Others seem to agree that filezilla faster than winscp.

Batch files to show the User/System environment variables stored in registry – via: Stack Overflow
Posted by jpluimers on 2016/09/20
I wrote two tiny batch files that would dump the environment variables from the registry.
Various reasons:
- Environment variables can be stored in two contexts: System and User (SET will show them all at once and for instance combine PATH up to 1920 characters).
- Environment variables can be set to auto-expand or not, which you cannot see from a SET command (REG_EXPAND_SZ versus REG_SZ).
show-user-environment-variables.bat:
reg query "HKCU\Environment"
show-system-environment-variables.bat:
reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
Filtered results:

4K/5K monitors: when your RDP session has small black bands limiting the height/width to 2048/4096 pixels
Posted by jpluimers on 2016/08/29
Sometimes RDP limits you to 2048 pixels vertical (or 4096 pixels horizontal)
Just found out why on some Windows versions, the RDP sessions form my 4K monitor has some small black bands on top/bottom: older versions of Windows limit their RDP server to 4096 x 2048.
A 4K monitor will not hit the width limit (as 4K cheats: it is usually “just” 3840 pixels wide), but it does hit the height limitation (2160 is slightly more than 2048: you miss 112 pixels that show as two small black bands).
A 5K monitor is worse: it will hit both limits (5K does not cheat: at 5120 × 2880 it is exactly 5*1024 pixels wide) so you miss 124 pixels horizontally and a whopping 832 pixels vertically.
Don’t buy a 5K monitor yet if you do a lot of RDP work to older Windows versions.
The link below has a table listing various Windows versions, but it omits end-of-life versions so I’ve done some testing: Windows XP, Windows Vista, Windows Server 2003 and Windows Server 2003 R2 share the same limitations as Windows Server 2008 most likely because their latest service packs share the same RDP 6.1 version.
I updated this in the table:
