How to disable Cortana and Web Search in windows 10 anniversary update (2016)
With the newest update, windows has hidden the option “search online and include web results” and therefore has made it difficult for users to disable Cortana and Web results completely.
Luckily for us there is a relatively easy fix.
- Type Win + R to open run and type in gpedit.msc
- Go to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Search
- Disable “Allow Cortana”
- Enable “Do not allow web search”
And Done.
How to stop a Windows 10 update in progress

How to increase scope (change netmask) in windows server 2012
As you may have noticed, there is no easy way to change the netmask of a scope. The only way is to delete and recreate it.
If you have a network anywhere near as complex as the one I’m dealing with right now, you KNOW manual insertion is not even remotely an option. Luckily there is an easy way…. command prompt 🙂
Step 1. open up cmd as administrator and export your scope
The command is:
C:>netsh dhcp server \dhcp_server_name scope my_scope dump>c:dhcp.txt
eg. C:>netsh dhcp server \dc1 scope 192.168.1.1 dump>c:dhcp.txt
Step 2. Open that document and find the line saying
Dhcp Server \xyz.domain.local add scope 10.0.10.0 255.255.255.0 “scope_name” “scope_description”
and change the netmask to whatever you wish it to be… In my case I changed to 255.255.254.0 for an extra 255 Ip addresses so instead of 192.168.1.1-254 I have 192.168.1.1 – 192.168.2.254
Step 3. Delete your scope…
Yes, delete your scope… Be sure that you have opened up the dhcp.txt and confirmed that all your reservations and other configurations are stored in there. (Note. delete using the default GUI MMC console)
Step 4. Import modified scope.
I called my modified scope dhcp_custom.txt and so I will import it with
C:>netsh exec c:dhcp_custom.txt
done and done!!
How to sync time with NTP server in windows
To sync your time with a known local timeserver/domain controller, open up CMD (preferably with administrative privileges) and type
net time timeserver /set /yes
If you instead want to sync with an external time server.
w32tm /config /syncfromflags:manual /manualpeerlist:pool.ntp.org /reliable:no /update
Another useful command to note is:
w32tm /stripchart /computer:si.pool.ntp.org /samples:5 /dataonly
this will check the difference between current time and external ntp server.
How to change default bootloader in Windows
This applies for windows 7 and 8. Normally you would want to do this after installing a secondary operating system and it took over your main bootloader. (you would notice a restart when choosing the main os)
- Open cmd with elevated privilages
- bcdedit /default {current}
- restart
An additional tip to speedup the restart of your pc is to hold down shift when restarting… This will prompt you to choose what os you want before all the preload stuff
