VSS fixing with PowerShell

With VSS writers till being a pain sometimes and mess up things like backups, I thought it would be useful to have the manual restarts of corresponding services scripted.

First we start with a function supplied on Technet here.
With the information pulled by this function I’ve created a little script which restart the services;

$ListVSS = Get-VssWriters | where {$_.StateDesc -ne "Stable"}

$VSSHash = @{

"DHCP Jet writer" = "DHCP Server"
"COM+ REGDB Writer" = "Volume Shadow Copy"
"Microsoft Hyper-V VSS Writer" = "Hyper-V Virtual Machine Management"
"WMI Writer" = "Windows Management Instrumentation"
"TermServLicensing" = "Remote Desktop Licensing"
"System Writer" = "Cryptographic Services"
"SqlServerWriter" = "SQL Server VSS Writer"

}

ForEach ($Writer in $ListVSS){
ForEach ($VSSService in $VSSHash.GetEnumerator()){

if($Writer.WriterName -eq $VSSService.Key){

Restart-Service -DisplayName $($VSSService.Value) -Force -verbose

}}}

If there are any other VSS writers stuck, here is an additional list of writers;

"ASR Writer" = "VSS Volume Shadow Copy"
"BITS Writer" = "BITS Background Intelligent Transfer Service"
"COM+ REGDB Writer" = "VSS Volume Shadow Copy"
"DFS Replication service writer" = "DFSR DFS Replication"
"DHCP Jet Writer" = "DHCP Server"
"FRS Writer" = "NtFrs File Replication"
"FSRM writer" = "File Server Resource Manager"
"IIS Config Writer" = "Application Host Helper Service"
"IIS Metabase Writer" = "IIS Admin Service"
"Microsoft Exchange Writer" = "Microsoft Exchange Information Store"
"Microsoft Hyper-V VSS Writer" = "Hyper-V Virtual Machine Management"
"NTDS NTDS" = "Active Directory Domain Services"
"OSearch VSS Writer" = "Office SharePoint Server Search"
"OSearch14 VSS Writer" = "SharePoint Server Search 14"
"Registry Writer" = "VSS Volume Shadow Copy"
"Shadow Copy Optimization Writer" = "VSS Volume Shadow Copy"
"SPSearch VSS Writer" = "Windows SharePoint Services Search"
"SPSearch4 VSS Writer" = "SharePoint Foundation Search V4"
"SqlServerWriter" = "SQL Server VSS Writer"
"System Writer" = "Cryptographic Services"
"TermServLicensing" = "Remote Desktop Licensing"
"WINS Jet Writer" = "Windows Internet Name Service (WINS)"
