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

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.

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:

Make A Bootable Windows 10 USB Install Stick On Linux With WinUSB Fork ~ Web Upd8: Ubuntu / Linux blog
Posted by jpluimers on 2016/07/29
One day I’m going to need this: Make A Bootable Windows 10 USB Install Stick On Linux With WinUSB Fork ~ Web Upd8: Ubuntu / Linux blog
So I’m glad WinUSB (which hadn’t been maintained for a long time) got forked on github by slaka.
Since my day-to-day unix-like system is OS X, I’d love a good working solution there too which means I probably need to investigate a bit along these lines:
- Using diskpart in a Windows VM (which is kind of backwards):
- diskpart and copying at Creating a Bootable Windows 7 USB Disk in OS X ML – post #18 | MacRumors Forums
- this should include getting the bootsector at Creating a Bootable Windows 7 USB Disk in OS X ML – post #23 | MacRumors Forums / Source: Creating a Bootable Windows 7 USB Disk in OS X ML – post #24 | MacRumors Forums
- Using Disk Utility and UEFI (only works for Windows 8 and up):
- Using Boot Camp Assistant and a modified Info.plist (which for El Capitan needs some extra work):
- Create a Windows 7 / 8 Bootable USB Drive with Mac – COMPLETE SOLUTION – Michael Anastasiou | Michael Anastasiou
- Works way better than using How to Copy an ISO to a USB Drive from Mac OS X with dd (this link is to the comment explaining Boot Camp Assitant is way better)

windows 7 – Available memory differs by several GiB from what is installed – Super User
Posted by jpluimers on 2016/07/01
Very interesting question and answers: windows 7 – Available memory differs by several GiB from what is installed – Super User.
Basically the missing memory can be due to:
- Windows licensing limitations
- Mapping of device memory into virtual memory space (especially on x86 systems)
This affects both server and client versions of Windows. Client versions are more restrictive because of the vast amounts of potentially faulty drivers involved.
Some links (read the full question for details):
- Pushing the Limits of Windows: Physical Memory – Mark Russinovich’s technical blog – TechNet Blogs.
- MemInfo v1.11 – January 2, 2008.
- The usable memory may be less than the installed memory on Windows 7-based computers.

Cool Windows tool of the day: RegJump by SysInternals
Posted by jpluimers on 2016/05/13
RegJump.exe is really cool, and has already there for more than a year (:
This little command-line applet takes a registry path and makes Regedit open to that path. It accepts root keys in standard (e.g.
HKEY_LOCAL_MACHINE) and abbreviated form (e.g.HKLM).usage: regjump <<path>|-c> -c Copy path from clipboard. e.g.: regjump HKLM\Software\Microsoft\Windows

findstr as alternative for recursive grep search
Posted by jpluimers on 2016/04/27
Usually I use the old Borland grep.exe that still ships with Delphi. Too bad it is 16-bit app which does not recognise Unicode.
FindStr does. Though much slower and with limited regular expression capabilities, can do recursive searches too:
findstr /spin /c:"string to find" *.*
The /spin is a shortcut for these case insensitive command-line options (the full list of possible options is below):
/S Searches for matching files in the current directory and all
subdirectories.
/I Specifies that the search is not to be case-sensitive.
/N Prints the line number before each line that matches.
/P Skip files with non-printable characters.
Sometimes I leave out the /P to include binary files.

Some command-line tips for OpenSSL and file format (pfx, p12, cer, crt, key, etc.) conversion of certificates, keys
Posted by jpluimers on 2015/02/27
OpenSSL is really nice, but remembering all these command-line switches is difficult, especially when you do not use them often enough.
I don’t, and when I do there are a few common tasks I perform, and I was glad to find a few links with great information:
- Tips : Using openssl to extract private key ( .pem file) from .pfx (Personal Information Exchange) | Cycure.
- SSL Converter – Convert SSL Certificates to different formats.
- The Most Common OpenSSL Commands.
- OpenSSL Command-Line HOWTO.
- Powerpoint presentation: http://web.cs.dal.ca/~tt/ECMM6010/presentations/OpenSSL.ppt.
- How to Convert certificates between PEM, DER, P7B/PKCS#7, PFX/PKCS#12 | My Online Storage of Knowledge.
- Convert a CERT/PEM certificate to a PFX certificate – Stack Overflow.
- DER vs. CRT vs. CER vs. PEM Certificates and How To Convert Them.
- Knowledge Sharing…: Extracting Public Certificate and Private Key From PFX File.
- Verifying that a Private Key Matches a Certificate.
- Verifying that a Certificate is issued by a CA / encryption – How do you test a public/private keypair? – Stack Overflow.
- Tech Talk @ N3TLab.com: OpenSSL Windows – How to install, use and generate a SSL certificate.
(which also fixes the “WARNING: can’t open config file: /usr/local/ssl/openssl.cnf”). - ssl – What kind of private key is located in a PKC12 pfx file? – Stack Overflow.
( I’ve included this one because it explains the concept of X509, CA’s and private keys well). - Sending S/MIME email using OpenSSL.
- OpenSSL: Documents, openssl(1), as I always forget this nice list of commands:
openssl [ list-standard-commands | list-message-digest-commands | list-cipher-commands | list-cipher-algorithms | list-message-digest-algorithms | list-public-key-algorithms] - Secure E-Mail: Problems, Standards, and Prospects – The Internet Protocol Journal – Volume 2, No. 1 – Cisco Systems:
The OpenSSL documentation does not explain clear versus opaque signing. I prefer the latter as the whole email gets encapsulated in a base64 blob, so intermediate gateways have a much harder job messing around with the content. - Certificate Installation with OpenSSL – Other People’s Certificates.
I’ve converted them to batch files that run fine when copied to the directory where you put the x86 or x64 Windows version of OpenSSL (they assume %~dp0openssl.exe for the location of the OpenSSL.exe binary, just in case it is not on the path, or you have various tools that scattered around incompatible copies of OpenSSL binaries).
OpenSSL defaults to PEM format (that has text base64 strings), so if you get DER format (binary) you need to convert them.
A few errors I got and what they mean
Error decrypting PKCS#7 structure
Error decrypting PKCS#7 structure
5216:error:21070073:PKCS7 routines:PKCS7_dataDecode:no recipient matches certificate:.\crypto\pkcs7\pk7_doit.c:538:
5216:error:21072077:PKCS7 routines:PKCS7_decrypt:decrypt error:.\crypto\pkcs7\pk7_smime.c:557:
This error means that the recipient of the email does not match the certificate you pass in. What happens is that OpenSSL tries to decrypt the mail, it cannot match the certificate to the mail, and barfs. It usually happens when you have From/To reversed by accident.
Error decrypting PKCS#7 structure
Error decrypting PKCS#7 structure
4948:error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch:.\crypto\x509\x509_cmp.c:330:
4948:error:2107207F:PKCS7 routines:PKCS7_decrypt:private key does not match certificate:.\crypto\pkcs7\pk7_smime.c:552:
This means somewhere you mixed up a private and public key in the certificate files.
Use something like the OpenSSL wrapper verify-private-key-matches-certificate-x509-pem-cer.bat to verify them.
Error reading S/MIME message
Error reading S/MIME message
6900:error:0D06B08E:asn1 encoding routines:ASN1_D2I_READ_BIO:not enough data:.\crypto\asn1\a_d2i_fp.c:251:

6900:error:0D0D40CB:asn1 encoding routines:SMIME_read_ASN1:asn1 parse error:.\crypto\asn1\asn_mime.c:528:
OpenSSL does not like .EML files to end with a period (. which SMTP needs to process when sending an .EML file).
See https://gist.github.com/anonymous/7233372 and https://gist.github.com/anonymous/7233329
The former throws this error, the latter not. This is not caused the width of the base64 encoding (not yet archived at the WayBack machine), which I initially thought, but the terminating period.

Binary builds of Win64 and Win32 OpenSSL (via: Shining Light Productions)
Posted by jpluimers on 2015/02/20
The quickest way to get Win64 and Win32 binary builds of the youngest OpenSSL, you should get them from Shining Light Productions – Win32 OpenSSL.
Despite the link name, you can get the Win64 binaries from there too..
Besides binaries, they also have the source to build them from, and any other redistributable you’d need.
They run on virtually any Windows version, though I only used them on NT based Windows versions of XP/2003 and younger.
Two notes:
- you usually need the Visual C++ 2008 redistributables, of which there is both an x86 and an x64 version (the OpenSSL installer just tells you it is missing, and assumes you know if it is the x86 or x64 one).
- unless you are a software developer wanting to link to OpenSSL, the “Light” versions of the installs suffice.

Creating an ICO file from multiple PNG files: IcoFX versus ConvertICO.org
Posted by jpluimers on 2015/02/17
For Windows Vista and up, you need at least these icon resolutions:
- 16×16
- 32×32
- 48×48
- 256×256
For Windows XP / 2003 Server and earlier, you’d only need the 16×16, 32×32 and 48×48 resolutions, and if you support older video hardware, include them in 24-bit, 8-bit and 4-bit color depth.
For younger versions you might consider adding 20×20, 24×24, 40×40, 64×64 and 128×128 as well to support higher DPI modes.
You need to include and various other sizes for other operating systems.
Getting at them, I usually start with an EPS file, then downscale to the right resolution, and save the resulting files as PNG images, then assemble those together.
A while ago, I had some icons with nice long diagonal line, then I found out the hard way I should not have used ConvertICO.org. I often prefer on-line tools over off-line, especially for actions I rarely do (this is one of them). It saves you from installing software, and on-line sites usually get better over time.
In this case, I shouldn’t have gone online: Just look at the jagged edges in the 200% zoom below: the image on the right is from ConvertICO.org, on the left it is from IcoFX.
What you clearly see is that ConvertICO messes around with the 256×256 image (it doesn’t mess around with the other resolution), but IcoFX doesn’t mess around.
So now I switched to IcoFX. Not on-line, but a great free tool. Read the rest of this entry »
