In certain conditions after Windows XP installation your may end up with two Windows XP entries in boot.ini file.
During Start-Up this will appear as a following screen, asking you to select which Operating System you want to run.



This OS selection screen is only useful if you genuinely have two or more Windows installations on the same PC. Otherwise you probably want to get rid of it.

First of all you need to find out which entry is correct. Simply select each entry during start-up and see which one actually loads your Windows installation. If both of them load the same OS, just remove the second one.

Now you have two ways to fix the problem:

1. Advanced - Edit your boot.ini file

Be careful editing boot.ini file. If you make a mistake Windows will refuse to boot. This can be fixed, but make sure you know what you are doing. If you unsure use second option.

• Boot into Windows and open System Properties:
  
  • Right click on My Computer and select Properties
    or
  • Start > Run > sysdm.cpl > OK
• In Advanced tab, Startup and Recovery section click on Settings
• In System Startup section click on Edit
  
• This will open boot.ini in notepad

It will look similar to this:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

In [operating systems] section you have entries listed in the above startup screen. Simply delete the whole line with the incorrect entry and save changes.
Restart the computer and OS selection screen should be gone. As I mentioned above if you made a mistake Windows will refuse to boot.

2. Safe - Change default OS and disable timer

• Boot into Windows and open System Properties:
  
  • Right click on My Computer and select Properties
    or
  • Start > Run > sysdm.cpl > OK
• In Advanced tab, Startup and Recovery section click on Settings
• In Default Operating System drop down select correct entry
• In Time to display list of operating systems box reduce time to only couple of seconds.
• Save changes and restart computer.

OS selection screen will still appear but only for couple of seconds so it won't get in a way so much. If made a mistake selecting default OS and computer refuses to boot, you can still quickly change OS using cursor keys.
Now, when you are sure that the default OS is selected correctly, you can remove to OS selection screen completely:

• Boot into Windows and open System Properties:
  
  • Right click on My Computer and select Properties
    or
  • Start > Run > sysdm.cpl > OK
• In Advanced tab, Startup and Recovery section click on Settings
• Remove checkbox from Time to display list of operating systems
• Save changes and restart computer.

A user reported after logging-in into Google Adsense account a blank page is displayed. This only happened in Firefox. Google Chrome and IE worked fine.

First step was to disable all Firefox add-ons which immediately fixed the problem. Actual offending add-on was AddBlock Plus.
AdBlock Plus (ADP) can be quite useful add-on, so instead of disabling it you can simply add Google Adsense to AdBlock exceptions. Simply login into Adsense account, click on ADP icon and select Disable on this page.

After upgrading to MS Outlook 2010 some users started reporting an intermittent issue:
Occasionally messages get stuck in outbox even if Outlook is connected to the Exchange Server and shows that all folders are up to date. When a user clicks on Send Receive, Outlook hangs or crashes. After Outlook is restarted all messages from outbox are gone.
Sometimes Outlook would hang simply typing a message. Outlook AutoSave feature was also working sporadically, sometimes not saving messages even after 10-20 minutes when it was set to autosave to drafts every 3 min.
All this resulted in users losing some carefully crafted emails causing lots of frustration.

A quick Google search revealed number of people complaining about the same issue on MS forums, but no real solution.

First of all, we tried the following:

• Disable all add-ins
• Recreate new profile
• Reinstall MS Office

Nothing helped.

Then we checked Outlook versions within a company and it appeared that all affected users were using version 14.0.5123.5000 when the rest of the company was on 14.0.6023.1000, which is actually Outlook 2010 SP1.
Installing MS Office 2010 Service Pack 1 definitely helped, but the issue wasn't completely resolved. 

Eventually we tracked that the problem was caused by users storing .pst files in network locations. Mostly it affected users who were moving with their laptops around a lot (connecting and disconnecting from the network).
