Avast + The Bat Errors:

1) Better Windows 7 Cleanup
Windows 7 Ultimate  32bits (clean)
before : used 15.5 GB  (clean install + all updates to jan 2014)
afeter : used 12.3 GB
  (after all procedures described below)

1) Clean Browsers Cache

Add Firefox portable location:
 - Open CCleaner.exe -> Options -> Advanced -> Save all settings to INI file
 - Open "As Administrator" C:\Program Files\CCleaner\ccleaner.ini  and add line with path to Firefox portable location:
 - CustomLocation1="FIREFOX|z:\FirefoxPortable\Data\profile"
 - z: is RAMDISK in my case

2) Disable Hibernation, delete hyberfile.sys
#  Run CMD as Administrator
C:\Windows\system32>powercfg -h off

3) Windows Disk Cleanup
#  Run CMD as Administrator

%SystemRoot%\System32\Cmd.exe /c Cleanmgr /sageset:65535 & Cleanmgr /sagerun:65535

4) Cleanup some cache and update folders from Windows#  Run CMD as Administrator
C:\Windows\system32>net stop wuauserv
The Windows Update service is stopping.
The Windows Update service was stopped successfully.

C:\Windows\system32>net stop bits

3) GPSvcGroup
After several Windows 7 updates, my PC didnt boot-up correctly, so I did manual reboot.
When Windows 7 finally boot-up, the following error appears:

Resolution :
Or Create regulat text file and save as .reg file:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Svchost]

4)Hardware acceleration
Is some situation (not fast videocard) it is better to disable hardware acceleration from Flash and firefox.

5) Windows network settings backup and restore

netsh interface ip dump > c:\ipconfig.txt
# ----------------------------------

# ----------------------------------
pushd interface ipv4

set global icmpredirects=enabled taskoffload=enabled
add route prefix= interface="iftype0_0" nexthop= metric=1 publish=Yes

add address name="vlan97" address= mask=
add address name="FIZIC" address= mask=
add address name="MS Loopback" address= mask=

# End of IPv4 configuration

To re-import it:
netsh -c interface –f c:\ipconfig.txt”

Show Interface configuration

netsh interface ipv4 show config

Only IP Addresses of all LAN adapters

netsh interface ipv4 show address

Show global TCP/IP Parameters

netsh interface ipv4 show global

Disable and enable a Interface

netsh int set int name="ethernet" admin=disabled
netsh int set int name="ethernet" admin=enabled

Show all network  interfaces and its link state

netsh interface ipv4 show interfaces

Print the routing table

netsh interface ipv4 show route

Show all tcp connections

netsh interface ipv4 show tcpconnections

Which Multicast groups are joined
netsh interface ipv4 show joins

Show dynamic portrange for outgoing connections
netsh interface ipv4 show dynamicportrange protocol=tcp

Set a static IP Address (, Subnet Mask ( and Gateway ( on a specific interface (Local Area Connection 2) persistent

netsh interface ipv4 set address name="Local Area Connection 2" static store=persistent

and temporary up to the next reboot and the parameters at full length. After the reboot the IP Address is empty.
netsh interface ipv4 set address name="Local Area Connection 2" static address= mask= gateway= store=active

Set DNS Servers without a DNS check, the  set dnsservers command supports only one server as argument

netsh interface ipv4 set dnsservers name="Local Area Connection 2"  source=static address="" validate=no

you have to add a second DNS Server with the add dnsservers directive

netsh interface ipv4 add dnsservers name="Local Area Connection 2" address="" validate=no index=2

Set IP Address assignment on Interface to DHCP

netsh interface ipv4 set address name="Local Area Connection 2" source=dhcp

and also the DNS Servers

netsh interface ipv4 set dnsservers name="Local Area Connection 2" source=dhcp

Add a route  for subnet over interface “Local Area Connection 2” and router

netsh interface add route prefix= interface="Local Area Connection 2" nexthop=

Note: Since Windows Vista its not possible to set the dns search suffix with netsh, you have to use WMI for this.
To set the DNS search suffix use powershell and wmi.
Define your Domains

Get the WMI Class to invoke the static method SetDNSSuffixSearchOrder

$oNetworkadapterConfiguration=[wmiclass]"Win32_NetworkadapterConfiguration" $oNetworkadapterConfiguration.SetDNSSuffixSearchOrder($aDNSSearchSuffixes)
Or invoke the method directly by calling the Invoke-WmiMethod commandlet

Invoke-WmiMethod -Class Win32_NetworkadapterConfiguration -Name SetDNSSuffixSearchOrder -ArgumentList @(@("subdomain.domain1.local","subdomain.domain2.local"),$null)

Invoke-WmiMethod -Class Win32_NetworkadapterConfiguration -Name SetDNSSuffixSearchOrder -ArgumentList @($aDNSSearchSuffixes,$null)
Note: If the aDNSSearchSuffixes Array contains more then one element a second parameter of $null is requiered otherwise the Invoke-WmiMethod command failed with error: Invoke-WmiMethod : Unable to cast object of type ‘System.String’ to type ‘System.Array’.
