Defragment the NTFS MFT and other hidden crucials in live Windows
article #1265, updated 37 days ago

The command is CONTIG (also available in 64-bit as CONTIG64), and it is a Sysinternals:

https://docs.microsoft.com/en-us/sysinternals/downloads/contig

You’ll want to put the appropriate binary in C:\Windows. Run it like this, in administrative CMD, it will get all of the hiddens it can for C drive (this is 64-bit):

contig64 -nobanner -accepteula C:$Mft
contig64 -nobanner -accepteula C:$LogFile
contig64 -nobanner -accepteula C:$Volume
contig64 -nobanner -accepteula C:$AttrDef
contig64 -nobanner -accepteula C:$Bitmap
contig64 -nobanner -accepteula C:$Boot
contig64 -nobanner -accepteula C:$BadClus
contig64 -nobanner -accepteula C:$Secure
contig64 -nobanner -accepteula C:$UpCase
contig64 -nobanner -accepteula C:$Extend

Notice the distinct lack of slashes in the above!

In an administrative PowerShell, all of the following. Reports suggest increases in performance if there are CPU cycles available:

Enable-MMAgent -ApplicationLaunchPrefetching
Enable-MMAgent -ApplicationPreLaunch
Set-MMAgent -MaxOperationAPIFiles 8192
Enable-MMAgent -MemoryCompression
Enable-MMAgent -OperationAPI
Enable-MMAgent -PageCombining

Using Contig to defrag
article #1266, updated 80 days ago

The command is CONTIG (also available in 64-bit as CONTIG64), is a Sysinternals:

https://docs.microsoft.com/en-us/sysinternals/downloads/contig

It defrags, and does it very well. It does it file by file. Here’s a command probably suitable for background operation on a whole C drive, on a 64-bit machine, quiet mode:

start /LOW contig64 -s -q C:\*

Recreate SBS monitoring database by PowerShell
article #866, updated 139 days ago

Really good article here:

http://www.itquibbles.com/sql-sbsmonitoring-high-disk-usage/

Solves the problem of the database reaching max capacity, and also speeds things up in general.

Short version:

In SBS 2008, run the contents of this zip file in an administrative PowerShell window.

In SBS 2011, start this shell as administrator:

C:\Program Files\Windows Small Business Server\Bin\MoveDataPowerShellHost.exe

and then while in the shell, run the contents of this zip file.

If it says “1 row affected”, it’s done, and the messages will point out old MDF and LDF files to remove.

You may notice that the script linked here is just a tad different than the one on the itquibbles page; this one just adds the -force items mentioned as an option on that page.

Disable Microsoft compatibility telemetry by Group Policy
article #1248, updated 169 days ago

Local group policy has this here in Windows 10:

Computer Configuration, Administrative Templates, Windows Components, Data Collection and Preview Builds

We may disable “Allow Telemetry” and enable “Do not show feedback notifications” for excellent effect.

Domain group policy will only have the above, if it has been upgraded (or installed) with the appropriate very recent version of Group Policy templates.

Windows Performance through VSS Cleanup and Preassociation
article #1004, updated 315 days ago

These steps can improve Windows performance a whole lot. It works because a vast array of different applications and services in Windows utilize VSS on their backends. All of the below, except for one server-only step sometimes needed, is encapsulated in PowerShell script (3.0 and up) OVSS.ps1 , part of the windows-tools project.

To do the VSS optimization interactively, start an administrative CMD, and then…

Step 1:

vssadmin Delete Shadows /All

If there are orphan shadows, you will be asked whether you want to delete them. If there are and you delete them, you will see immediate performance benefit. Reportedly, Windows autodeletes them only after there are 64 per volume. We prefer to see zero! These build up as a result of bad shutdowns, drive and drive controller issues, and insufficient RAID resources to serve demands.

Step 2:

We now improve any existing preassociation of disk space for VSS. On some machines, this will increase performance very impressively, immediately. In general it keeps them smooth and stable and prevents hesitations. This does not reserve or take up the space, it just “associates” it, makes it ready for use, so that whenever Windows wants to do any of the bajillions of things it does with VSS, things ranging from tiny to enormous, it can skip that step.

It is worthwhile to know that C: on all workstation installs and many server installs, has a minimal preassociation already set up. And we should check to see if it has been done. So the first step is to check it. Do the below:

vssadmin list shadowstorage

If it gives you something like this:

vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2013 Microsoft Corp.

Shadow Copy Storage association
   For volume: (\\?\Volume{84214e3c-0000-0000-0000-100000000000}\)\\?\Volume{84214e3c-0000-0000-0000-100000000000}\
   Shadow Copy Storage volume: (\\?\Volume{84214e3c-0000-0000-0000-100000000000}\)\\?\Volume{84214e3c-0000-0000-0000-100000000000}\
   Used Shadow Copy Storage space: 0 bytes (0%)
   Allocated Shadow Copy Storage space: 0 bytes (0%)
   Maximum Shadow Copy Storage space: 100 MB (20%)

Shadow Copy Storage association
   For volume: (C:)\\?\Volume{84214e3c-0000-0000-0000-501f00000000}\
   Shadow Copy Storage volume: (C:)\\?\Volume{84214e3c-0000-0000-0000-501f00000000}\
   Used Shadow Copy Storage space: 0 bytes (0%)
   Allocated Shadow Copy Storage space: 0 bytes (0%)
   Maximum Shadow Copy Storage space: 373 GB (20%)

where “Maximum Shadow Copy Storage space: “ for each volume is set to 20%, the rest has been done, you are fully optimized. Otherwise, if this is a desktop OS, we resize the existing association for each volume. For volumes without letters, and to pull a list of all VSS-ready volumes, see the note towards the end of this document.

So for the C drive, do the below in administrative CMD:

vssadmin Resize ShadowStorage /For=C: /On=C: /MaxSize=20%

Do repeat for any other active hard drive partitions, D:, E:, et cetera. Don’t worry if you get an error, the next step covers it.

Step 3:

It may well throw an error, saying there is no such association. If this is a workstation OS, vssadmin lacks two commands which we need for any further steps, so in that case we are done. But on any Windows Server OS from 2008R2, if the error was thrown, we do an Add:

vssadmin Add ShadowStorage /For=E: /On=E: /MaxSize=20%

Step 4:

And finally (server only), one more thing which can help if, for instance, C: is almost full but E: has plenty of space:

vssadmin Delete ShadowStorage /For=C: /On=C:
vssadmin Add ShadowStorage /For=C: /On=E: /MaxSize=20%

This maximizes overall performance, and also prevents possible backup failures and other issues due to insufficient disk space on C:.

Note:

On some machines, the volumes do not have letters. For these you will need to use the volume GUID path. In vssadmin list shadowstorage, they look like this:

Shadow Copy Storage association
   For volume: (\\?\Volume{99ac05c7-c06b-11e0-b883-806e6f6e6963}\)\\?\Volume{99a
c05c7-c06b-11e0-b883-806e6f6e6963}\
   Shadow Copy Storage volume: (\\?\Volume{99ac05c7-c06b-11e0-b883-806e6f6e6963}
\)\\?\Volume{99ac05c7-c06b-11e0-b883-806e6f6e6963}\
   Used Shadow Copy Storage space: 0 B (0%)
   Allocated Shadow Copy Storage space: 0 B (0%)
   Maximum Shadow Copy Storage space: 32 MB (32%)

For such a situation, substitute \\?\Volume{99ac05c8-c06b-11e0-b883-806e6f6e6963} (the whole long string) for C: in the above command lines.

PowerShell will give GUI paths for all volumes thusly:

GWMI -namespace root\cimv2 -class win32_volume

RUNALL and RUNMOST: Speed up Windows several different ways
article #1182, updated 315 days ago

RUNALL.CMD is the best way to run our very own windows-tools, a Windows cleanup, optimization, and speedup toolset, on an Internet-connected Windows PC. It requires Powershell 3.0 or newer, which comes with Windows 8 or newer, and can be installed into Windows 7 using the WMF. There is just one gotcha: Offline Files compatibility of all folders shared from the PC, “share caching”, is turned off, for one of several significant hikes in performance and overall reliability. If you need Offline Files, you’ll want RUNMOST.CMD, which does it all except this one item.
