Hi Robear;
Thank you kindly for your thoughtful and comprehensive reply.
Below are my answers to your diagnostic questions, using your numbering list.
1.a I chose to install MSE few years ago. It had been working fine till last week’s Update (OP, Item
1)
The PC (Win XP Home, SP3,
32-bit) now works only in Safe Mode.
1.b MSE was created: October 25, 2010
1.c MSE version: 4.0.1526.0
1.d I don’t remember the Definitions version, since I can no longer Open
MSE.
Open MSE produces the Error:
Microsoft Security Client
An error has occurred in the program during initialization.
If this problem continues, please contact your system administrator.
Error Code: 0x80070715
OK
2. I used Norton Antivirus, then Windows Live OneCare Antivirus on this computer years ago before switching to
MSE.
3. Yes, I had Norton on this PC a while back.
4. I don’t remember whether a Norton trial version had been initially installed, but I remember paying the yearly subscription for its renewal for a number of years.

Q1: Are the above "missing" KBs critical ??
Q2: Could I search for each of the above missing KB at microsoft.com for Win XP and download them ??
Q3: C ould it be done with Windows running in safe mode ??
There is NO KB displayed as Security Update for Windows Internet Explorer 8 under
Security Update for Windows XP.
There’re however 21 KB updates under Security Update for Windows Internet Explorer 8
Q4: Is that what you meant ??
6.a “No working Java was detected on your system. Install Java by clicking the button below.”
I didn’t.
Q5: Should I ??
6.b “You have Adobe Flash Player version
8.0.22.0 installed.”
Q6: Should I upgrade to: Internet Explorer (Windows 8) .... Player version
11.3.375.10 ??
7. There might be Firefox, Chrome, MSN Explorer, etc., but I don’t recall using other than IE8 on this computer.
With the unfamiliar desktop layout in safe mode, it is not easy to remember or to navigate!
8. Not before Oct 2, 2012.
In the last couple of days, however, I used:
a. Microsoft Safety Scanner– 1.0.3001.0 (full system scan, twice)
b. PC-Doctor diagnostics (3 times)
c. IBM Enhanced diagnostics (3 times)
All tests passed with flying colours.
9. I don’t recall ever performing Windows XP Repair Install.
