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

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:
- 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:
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\Â 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

Slightly updated the answer the /D YÂ 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 /T
The 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.

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.

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:

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:

Attack from the ’90s resurfaces more deadly than before
Source: Windows Flaw Reveals Microsoft Account Passwords, VPN Credentials
TL;DR: block LAN->WAN port 445
Note this won’t affect web-dav shares like \live.sysinternals.com\DavWWWRoot as that uses ports 443 and 80.

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 WinUSBÂ (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):
- 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):

Very interesting question and answers:Â 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):
