Why do Windows 10 Cumulative Updates keep failing with error code 0x80070003?[01-Nov-2023] I was experiencing persistent failures to install the monthly Cumulative Update to Windows 10 with error code 0x80070003 (ERROR_PATH_NOT_FOUND). In my case, this was caused by broken driver install for a Qualcomm Atheros WiFi card, which meant a directory required for restoring system files using the System File Checker of Windows was missing. However, it seems that other drivers can be culprits as well. What helped me fix this issue were these two sources:
Notes to self
has a good step-by-step guide to troubleshooting this type of installer problems, with a list of log files to check that seem useful for troubleshooting
installation issues in general:

Why does my Windows 8 PC turn itself on at the same time every day?[15-Dec-2012] After upgrading from Windows 7 to Windows 8 a few weeks ago, I found that my PC would power up from Hibernation at 12:53pm (precisely) every day. Eventually it turned out that a Scheduled Task called mcupdate_scheduled ("Check for Media Center updates") had the flag "Wake the computer to run this task". This is the issue described in this KB article from Microsoft - unfortunately this type of article is only easy to find if you know the magic keyword "mcupdate_scheduled" already...
Interestingly, Media Center and the mcupdate.exe executable had been removed in the upgrade to Windows 8, so the task had become useless anyway and failed with error 0x80070002. Disabling the task fixed the power-up problem. It should be noted that the "Wake the computer to run this task" setting overrides the global option "Sleep" > "Allow wake timers" under "Advanced power plan settings" for the current plan.
Update: There seem to be other "system maintenance" jobs that can also make a Windows 8 PC power itself up for things like installing updates. I am still trying to collect a more complete list here...
How to avoid drive-by downloads of the ask.com toolbar with each update of the Java runtime (JRE)[15-Aug-2012] Oracle still continues the questionable practice of bundling the ask.com toolbar with each security update of the JRE, even going so far as requiring the user to opt-out of the installation of the potentially unwanted additional piece of software.
To avoid this, do not download the "standard" ("Online") version
of the JRE, but instead go here
and install the "Windows x86 Offline" installer - once you
installed this version for the first time, future downloads will
also exclude the ask.com toolbar. This is probably a particularly
good idea if you are installing JRE for someone else who may not
want to be nagged each time there is a new security patch.
Update [17-Oct-2014]: While the above "trick" no longer seems to work, Oracle have now added an option to the very bottom of their Java control panel's "Advanced" tab named "Suppress sponsor offerings when installing or updating Java". Check this, and you should be done - very useful if you are setting up a PC for someone else. See How-To Geek for more details.
In the German version, the option is called "Sponsorenangebote während der Installation oder Aktualisierung von Java unterdrücken".
Here are some utilities that helped me out of a bind at least once...
- ntldrismissing.com -
Miles Comer's "magic" boot disk that can recover from some
situations where a Windows XP machine produces the "NTLDR is
missing" message, for example after defragmenting the hard
disk and accidentally moving a system file to a region that
the default BIOS boot loader cannot access.
- Free EaseUS
partition recovery tool - helped me get back access to
my data partition after a resize with Partition Magic went
wrong, leaving the partition table with incorrect partition
- Vector Magic for tracing bitmap images to create vector drawings. The online serivce allows trying out as many images as you like, and lets you download two results for free before becoming paid.
